These results are with DWCAS backoff of 16 - it may be (may well be) this is a non-optimal choice and is depressing performance.
I’m about to add code to iterate over a range of backoff values.

So with 1 thread per physical package (i.e. not hyperthreading), liblfds is WAAAAY out in front. However, when we max out - one thread per logical core - the pthread spinlock wins. What’s amazing and unexpected is that the shared pthread spinlock is substantially faster than the private spinlock!
I’m about to examine the source code for pthread spinlocks. I guess they’re doing some extra work, which makes them more efficient - and also they only have to CAS, whereas the freelist is using DWCAS. However, I think the main issue here is the DWCAS backoff in the freelist - when we go to one thread per logical core, there’s a lot more contention, and that backoff is being invoked much more often (I think!)
This is with DWCAS backoff set to 2 (rather than 16).

There are variations on the order of 10% for the non-locking benchmarks, compared to the previous post. I think what’s happening is thermal throttling, in my laptop. It’s not a stable benchmarking platform. I need to rate limit the CPU to something sustainable and then benchmark.
(This is on a Core i5).
Fixed two bugs. First, the test were running for about three times as long as they should - the performance numbers were correct in relation to each other, but were themselves incorrect. Second, I forgot to init the liblfds library, and so the PRNG was always returning 0, which totally fubared backoff! I thought about adding an assert for this in 7.1.0 but decided not to - I’m going to add it now; it’s a nasty silent failure, because for example when the PRNG is correctly initialized there’s a massive (3x) performance improvement in the freelist (when running one thread per physical core - other factors come into play in other thread combinations - mainly memory contention).
Current results (DWCAS backoff set to 16) on Linux on a Core i5 are…

The freelist result is great - when running one just one logical core, or when running on all threads on a single logical core, the pthread spinlocks win; but when moving out over multiple cores, liblfds is four to five times faster. I suspect the magnitude of the win will grow as the number of cores increases - experiments on Amazon with high core counts to follow.
The queue result is similar but the order of improvement is much smaller and indeed with one thread on every core, there is no improvement - but here I suspect the memory bus is getting saturated; but it could be related to the backoff value. More experiments to follow.
Benchmark results from a Raspberry Pi2 Model B - a single package, four physical core, non-hyperthread ARM processor.
The results are not clearly understandable to me. All of this also has the unknown factor of how much the DWCAS backoff value of 16 is a good or bad choice - and this could be affecting results hugely.
With the freelist, pthread spinlocks seem to perform very poorly on ARM, compared to Intel. The lock-free freelist wins across the board, and by 2x or 3x - the exception being the GCC 4.7.3 or better intrinsics, which are about 10% faster. I’m guessing the pthread spinlocks are issuing load and store memory barriers - because I suspect the sync intrinsics do this, and they’re running at the same speed, and liblfds doesn’t, and it’s running at basically the same speed as the GCC atomic intrinsics.
When we come to every core running, liblfds is way out in the lead - about 2x over GCC atomics and so 3x over pthreads/sync.
The queue is a different matter. There’s quite a bit more atomic working being done and so its behaviour is really very different to the freelist. Lock-free is performing about as well, sometimes a bit better, sometimes a bit worse, as the GCC atomics and the pthread spinlocks.
Experiments with the backoff value are now required.

I’ve added to the benchmark the capability to benchmark a range of DWCAS backoff values.
Performance is sensitive to the backoff value - the difference in performance can be as large as about 8x - it really matters. Also, as I suspected, the optimal backoff value varies by data structure (so I can’t have as I do now one global value).
When running a single thread the backoff value doesn’t matter - you never collide with yourself.
When all the threads running are on the same physical core (i.e. say a four hyperthread physical core, so four logical processors, but all on the same core), backoff makes no or almost no difference, regardless of data structure - the physical processor knows what’s going on across all its logical cores and arranges scheduling so there are no collisions.
When we move threads out across multiple physical cores, though, the backoff period makes a lot of difference to performance. My current (untested) thought in this case is that setting the backoff correctly for the maximum workloads is the right choice; to the extent you’re less busy than that, you’re less likely to be having collisions anyway, and so you care less and less about the backoff value being right.
I need to test this though. I need a partial load benchmark - right now I have a full load benchmark, where the threads run a tight loop simply performing pop/push or dequeue/enqueue calls. So I need a loop basically with a controllable delay between atomic ops, and I need to vary that delay.
Turning now to the results (which are getting longer and longer!), we can firstly set aside the single-thread and all-threads-on-one-physical-core thread sets, as backoff doesn’t matter.
The DWCAS range tested is 0 to 10, inclusive.
If we look then as the other two thread sets, one thread per physical core and one thread on every logical core, we see for the freelist as the DWCAS backoff increases, performance increases. We do not in fact see performance decrease, so even a backoff of 10 is too small (although the increases have become small by then).
If we look however at the queue, we see with one thread per physical core the optimal DWCAS backoff is 6. This gives a peak of 40,205,165 operations per second. If we increase or decrease backoff by one - just one! - we lose about 10,000,000 operations per second. Whooosh!
The problem is, this backoff value is only going to be right for my particualr processor with its particular clock speed.
If we then look at one-thread-on-every-logical-core, we see - awkwardly - performance still rising as we get to a backoff of 10. However, in this case, the difference is much, much smaller - going from DWCAS 0 to 10 adds about 4,000,000 operations; going from DWCAS 9 to 10 adds about 100,000 - probably a chance within the usual per-test variance.

So what do we make of it all?
If you are targetting a particular device, then you can find the optimal backoff values and use them - no problem.
If you are not, however, and so the processor model and clock speed can vary, then you could run the optimal backoff finder on an idle system of that type and use those values.
However, this may not be possible; in which case, other backoff values have to be used - and it just has to be hoped that they are reasonably correct, i.e. that backoff values don’t vary much across processor model and clock. Probably they do though - I mean, if a change of one in the queue backoff removes 25% performance, changing the clock speed by say 1 GHz is probably going to matter!
I wonder if it’s possible to build in something like automatic gain control.
Also - is the PRNG/ethernet-like random exponential backoff necessary? would a fixed backoff period work just as well, and so allow the removal of the PRNG complexity and passing around the PRNG state?
Somewhat puzzling results.
So, backoff matters - for freelist and as before when crossing physical cores.
That’s fine.
Now check the single-thread queue result for lock-free. It’s deterministic! that’s totally bizzare and unexpected - this is on a live (albeit idle) Linux system. It must be a bug!
Then, similarly, for the rest of queue, back-off seems to make no difference.
Now I have to figure out what’s going on here =-)

I modified the backoff to be non-exponential; to just be a fixed number of loop iterations.
First, here’s the one-thread-per-core result, with exponential backoff, for the freelist on ARM;
1 1 1 1 17640623,882031,19892,Lock-Free (DWCAS 0) 1 1 1 1 23285262,1164263,73337,Lock-Free (DWCAS 1) 1 1 1 1 26168142,1308407,84105,Lock-Free (DWCAS 2) 1 1 1 1 28152124,1407606,96889,Lock-Free (DWCAS 3) 1 1 1 1 29036007,1451800,116736,Lock-Free (DWCAS 4) 1 1 1 1 29464435,1473222,86809,Lock-Free (DWCAS 5) 1 1 1 1 29650621,1482531,95732,Lock-Free (DWCAS 6) 1 1 1 1 29559530,1477976,98744,Lock-Free (DWCAS 7) 1 1 1 1 29763734,1488187,94874,Lock-Free (DWCAS 8) 1 1 1 1 29939910,1496996,108147,Lock-Free (DWCAS 9) 1 1 1 1 30086056,1504303,62667,Lock-Free (DWCAS 10)
Now here’s the same, with a non-exponential backoff;
1 1 1 1 17013997,850700,14393,Lock-Free (DWCAS 0) 1 1 1 1 19076057,953803,490883,Lock-Free (DWCAS 1) 1 1 1 1 17042025,852101,14743,Lock-Free (DWCAS 2) 1 1 1 1 18177159,908858,42810,Lock-Free (DWCAS 3) 1 1 1 1 17071054,853553,45057,Lock-Free (DWCAS 4) 1 1 1 1 16705689,835284,33913,Lock-Free (DWCAS 5) 1 1 1 1 20509489,1025474,66327,Lock-Free (DWCAS 6) 1 1 1 1 17431414,871571,24032,Lock-Free (DWCAS 7) 1 1 1 1 17526509,876325,23812,Lock-Free (DWCAS 8) 1 1 1 1 18478460,923923,32485,Lock-Free (DWCAS 9) 1 1 1 1 18889871,944494,28001,Lock-Free (DWCAS 10)
Obviously, comparing these two sets of results, exponential has much better performance.
However, what exponential really means is - longer backoffs, when things get busy. This could in fact simply be approximately the same as - longer backoffs.
The exponential backoff, when set to a value of 10, has a maximum iteration count of 2^10 * 10 (10240), as the exponential part has a maximum power of 10, before it resets back to 1.
The results for a fixed period backoff of 10240-10250 are;
1 1 1 1 31359328,1567966,277086,Lock-Free (DWCAS 10240) 1 1 1 1 31350319,1567516,187042,Lock-Free (DWCAS 10241) 1 1 1 1 31350319,1567516,337291,Lock-Free (DWCAS 10242) 1 1 1 1 31367336,1568367,260849,Lock-Free (DWCAS 10243) 1 1 1 1 31372341,1568617,247379,Lock-Free (DWCAS 10244) 1 1 1 1 31375344,1568767,250752,Lock-Free (DWCAS 10245) 1 1 1 1 31363332,1568167,220210,Lock-Free (DWCAS 10246) 1 1 1 1 31349318,1567466,201058,Lock-Free (DWCAS 10247) 1 1 1 1 31353322,1567666,130502,Lock-Free (DWCAS 10248) 1 1 1 1 31353322,1567666,361582,Lock-Free (DWCAS 10249) 1 1 1 1 31351320,1567566,348364,Lock-Free (DWCAS 10250)
Well! ain’t dat interestin’. We have the same performance as with exponential - not quite as good, because the standard deviation is about 10x larger, which means the cores are not being treated as fairly; some cores are getting more, others less - but still, overall, three times faster than the original above.
At this point it is illuminating to display the results for a single thread.
1 31495464,6299093,0,Lock-Free (DWCAS 1024) 1 31495464,6299093,0,Lock-Free (DWCAS 1025) 1 31494463,6298893,0,Lock-Free (DWCAS 1026) 1 31495464,6299093,0,Lock-Free (DWCAS 1027) 1 31494463,6298893,0,Lock-Free (DWCAS 1028) 1 31495464,6299093,0,Lock-Free (DWCAS 1029) 1 31495464,6299093,0,Lock-Free (DWCAS 1030) 1 31495464,6299093,0,Lock-Free (DWCAS 1031) 1 31495464,6299093,0,Lock-Free (DWCAS 1032) 1 31495464,6299093,0,Lock-Free (DWCAS 1033) 1 31495464,6299093,0,Lock-Free (DWCAS 1034)
What we do understand from this? well, we see the total result is approximately equal to the total result for all four cores. In other words, there is a bottleneck, upstream of the cores, which determines maximum performance. (Memory bandwidth, basically).
Next I tried an outlier, with a non-exponential backoff of 4000-4010, and then another, 8000-8010.

Total throughput is the same, but the standard deviation doubles - so the 8000 backoff is worse, because the performance is the same but it’s less fair.
So we see, so far, that once the backoff is long enough, we reach the maximum performance allowed by the upstream bottleneck, but after that, we become more and more unfair.
So it would be instructive now to find the lowest non-exponential backoff which achieves maximum or nearly maximum performance (i.e. with the least unfairness).
This turns out to be about the 550 mark, if I pick about 30,000,000 as the target total ops.

And here, with non-exponential backoff 0-10;
1 1 1 1 17013997,850700,14393,Lock-Free (DWCAS 0) 1 1 1 1 19076057,953803,490883,Lock-Free (DWCAS 1) 1 1 1 1 17042025,852101,14743,Lock-Free (DWCAS 2) 1 1 1 1 18177159,908858,42810,Lock-Free (DWCAS 3) 1 1 1 1 17071054,853553,45057,Lock-Free (DWCAS 4) 1 1 1 1 16705689,835284,33913,Lock-Free (DWCAS 5) 1 1 1 1 20509489,1025474,66327,Lock-Free (DWCAS 6) 1 1 1 1 17431414,871571,24032,Lock-Free (DWCAS 7) 1 1 1 1 17526509,876325,23812,Lock-Free (DWCAS 8) 1 1 1 1 18478460,923923,32485,Lock-Free (DWCAS 9) 1 1 1 1 18889871,944494,28001,Lock-Free (DWCAS 10)
What do we draw from all this?
First, that large variations in the non-exponential backoff are required to make a difference to performance. Exponential side-steps this problem by increasing in a non-linear fashion, where the backoff value, although fixed, is on each iteration of backoff being mutiplied by 1 - 2 - 4 - 8 - 16 - 32 - 64 - 128 - 256 - 512 and finally 1024 (before going back to 1).
So the exponential backoff of 10 gives us a non-exponential backoff of 10, 20, 40, 80, 160, 320, 640, 1280, 2560, 5120, 10240.
What also see is that the lower the non-exponential backoff, the more fair the results - the lower the standard deviation (with the strange and not obviously explicable huge value for DWCAS 1, and that result repeats - it’s not a one-off). However, we also see that the lower the non-exponential value, the lower the overall performance.
We also see exponential backoff values from 4 to 10, inclusive, all give good performance and pretty good fairness.
My general view then - for the ARM platform, for what we see here may be totally different on MIPS or Intel, etc, or with many more cores - exponential backoff is better because it makes the choice of the correct backoff value MUCH less sensitive.
Next experiments are going to be on high-core count Intel systems. I want to see if the PRNG part of the backoff matters there, and I want to see how all the above pans out on a CAS system, rather than an LL/SC system.
I have not been looking closely enough at the results. Lots of digits in each number - easy to miss exactly how many digits difference there is between two numbers - and in particular I have not looked closely enough at the standard deviation column.
The back-off testing I’ve done so far has been on ARM.
I’ve been repeating the tests now on x64.
The standard deviation values are huge - i.e. one thread is dominating, the others are doing very little work.
I’ve modified the benchmark output to actually show the number of iterations performed by each thread.
Here’s an example, the freelist;
1 1 28060032,2806003,1295583,Lock-Free (DWCAS 0),18610592,9449440 1 1 44278234,4427823,2881935,Lock-Free (DWCAS 1),32328296,11949938 1 1 66740674,6674067,7405432,Lock-Free (DWCAS 2),59552493,7188181 1 1 76710634,7671063,5774912,Lock-Free (DWCAS 3),58772714,17937920 1 1 84710626,8471063,4498865,Lock-Free (DWCAS 4),58261203,26449423 1 1 99004906,9900491,11592576,Lock-Free (DWCAS 5),90488398,8516508 1 1 97875778,9787578,6058038,Lock-Free (DWCAS 6),70356286,27519492 1 1 99880781,9988078,5948326,Lock-Free (DWCAS 7),70970900,28909881 1 1 104587483,10458748,7230319,Lock-Free (DWCAS 8),77856779,26730704 1 1 109813704,10981370,11987819,Lock-Free (DWCAS 9),97290193,12523511 1 1 108797689,10879769,7387170,Lock-Free (DWCAS 10),80516436,28281253
One thread is generally doing about 70% to 80& of the work.
Now, it’s kinda interesting - very interesting in fact - to look at the values for the GCC spinlocks;
1 1 16391375,1639138,13448,GCC Spinlock (atomic),8148140,8243235 1 1 17053036,1705304,20385,GCC Spinlock (sync),8454446,8598590
These guys are very fair. I’m not quite sure how they’re doing it, in fact! although DWCAS 0 still is doing some work (I’ve not removed the back-off code, just set it so it’s always 0) and that might be in effect a back-off which the GCC spinlocks simply do not have.
But - fair as they are, if we compare them to all of the DWCAS values, we still see all DWCAS threads are doing more work than all of the GCC spinlock threads.
On ARM, this behaviour happens MUCH less. Here’s an example for ARM;
1 1 1 1 17640623,882031,19892,Lock-Free (DWCAS 0) 1 1 1 1 23285262,1164263,73337,Lock-Free (DWCAS 1) 1 1 1 1 26168142,1308407,84105,Lock-Free (DWCAS 2) 1 1 1 1 28152124,1407606,96889,Lock-Free (DWCAS 3) 1 1 1 1 29036007,1451800,116736,Lock-Free (DWCAS 4) 1 1 1 1 29464435,1473222,86809,Lock-Free (DWCAS 5) 1 1 1 1 29650621,1482531,95732,Lock-Free (DWCAS 6) 1 1 1 1 29559530,1477976,98744,Lock-Free (DWCAS 7) 1 1 1 1 29763734,1488187,94874,Lock-Free (DWCAS 8) 1 1 1 1 29939910,1496996,108147,Lock-Free (DWCAS 9) 1 1 1 1 30086056,1504303,62667,Lock-Free (DWCAS 10)
Now, I may be - ha, may WELL be - utterly wrong, but I suspect what’s going on here may be a combination of the difference between LL/SC and CAS, and the work the benchmark is doing.
The benchmark is simply a loop, where a thread pops and then pushes. The freelist starts with one element per thread.
Now, with CAS on Intel, as I understand it, a logical core will lock the cache line which is the target for the CAS, and then perform the operation.
So the benchmark begins, one of the threads gets to lock first, the other stalls, and then when the first is done, the second runs - and fails, because a push or a pop has occurred - and the other thread by then is probably stalling on its next pop or push, and it will again succeed, causing the second thread to fail again…
With LL/SC, there’s no stalling - every code just runs it code - and if some-one else performs the operation in question then our attempt fails.
So with CAS, it’s almost like we need to run the back-off on EVERY operation, not just a FAILED operation.
I’ve been testing PRNG exponential backoff (i.e. exponential with random selection of the backoff period within the maximum value) vs non-PRNG exponential, with one thread per logical core (as well as with one thread per physical core, as before).
Here’s one per physical core with PRNG;

The numbers in brackets after the per-thread operation counts are the logical core number - of the four logical cores on this processor, they are numbered “0 2 1 3”, so with these results we see cores 2 and 3 are in use, which is correct.
So what do we see?
We see that adding PRNG causes a great deal of unfairness. One core dominates the other. Removing PRNG ameilorates this problem.
Now for the same test, but with one thread per logical core.
Here’s with PRNG:

Oh boy. Wierd city, dude.
Without PRNG, one physical core dominates the other. Looking at DWCAS10, logical cores 0 and 2 (both in physical processor 0) get about 30m ops each, which logical cores 1 and 3 (physical 1) get about 13m each. It’s very unfair.
But now here when we add PRNG, wow! we do about 10% less work, but we’re MUCH more fair. All cores are doing about 20m ops.
I admit it. I’m lost. Anyone care to hit me with a clue bat?
I’m going to test this all now on a big amazon machine, with tons of cores, and see what I find there.

Dat’s EIGHTEEN physical cores, bro.
Who’da thunk it?
As long as we’re on one NUMA node, lock-free wins.
When we go over two NUMA nodes, pthread mutex wins, and the more cores we have, the more it wins by, AND it’s extremely fair.
Hmm. There seems to be a bug with the logical process ets, too - not all of them were generated or not all of them were run. Vexing!

Around halfway you’ll notice there’s a massive imbalance in per-core performance - that’s when we cross over into the second NUMA node. I think somehow the core which is in the next NUMA node gets a huge boost because it has a bunch of hardware all to itself (even though the freelist elements its using are in the other NUMA node - or maybe they’re not? the NUMA question is going to cloud these results a bit).
Without PRNG.
I need to fix the logical processor set generator and stripe the freelist elements over the NUMA nodes.
I suspect it won’t change the results though; pthread mutex wins when the number of cores is high.
Question is, how and why? I have two thoughts - firstly, maybe I need the backoff algorithm to be that the backoff value continues to increase for a run of the same result, i.e. as one thread keeps having successes, his backoff increases, and also as he keeps havings failures, too. It only resets to 1 on the swap from one state to the other.
The other thought is to add the scalable overlay, the hand-off which masks the freelist. I would have thought though this will help the mutex just as much as the lock-free approach - but it might well not be so.
Have to read the white paper and see how it works, too. I know the rough idea, but I’m not sure how the data structures are arranged.

The problem with the logical processor sets occurs when the sets move over into another NUMA node.
I’ve copied the appropriate /proc dirs so I can reproduce without paying 2 USD an hour :-)
One note - the VM I used for those test was on a dedidcated machine. Just me, no-one else.
It may be that all the results on the 36 core machine are invalid.
I’ve been looking into the malformed logical processor sets.
There’s a bug in how benchmark processes NUMA node cpumaps and it ended up with a mixed-up set of logical processors to NUMA nodes - God knows what effect this had on the thread distributions.
So, wow, stuff, and another 15 bucks of AWS time :-)
Current result is that on a single NUMA node, lock-free wins, but as soon as we go over multiple NUMA nodes, pthreads mutex wins.
I’ve been reading up on the mutex implementation and looking at the source code. My preliminary understanding is that the mutex works by having a queue of waiting threads, which are sleeping in the kernel, and when the thread currently holding the mutex goes to sleep, it goes and hands the mutex to the next thread (this is why it’s so fair).
The basic upshot is that the lock is inherently, by its design, acting to transform contention on a single memory location (the lock). This doesn’t win, if we’re on a single NUMA node - but as soon as we have a single thread on the second NUMA node, lock-free loses about 30% performance and mutex gains about 30% - and at that point, begins to win, and the more threads we have on the second NUMA node, the bigger the win.
The lock-free stuff shows some wierd-ass behaviour though over multiple NUMA nodes. For example, when we add the first logical core from the second NUMA node, all the threads on the first NUMA node go from like 3m ops each to about 400k ops each, but the single thread on the second NUMA node does 24m!
My current feeling is that something isn’t right with the way the chip or chipset is mediating cache line contention over NUMA nodes, and that’s basically destroying lock-free performance over multiple NUMA nodes. If it wasn’t for that, I think lock-free would still be beating mutex.
Regarding PRNG vs non-PRNG, well, for all considerations now we have to consider the one-NUMA-node scenarion vs the many-NUMA-nodes-scenario - right now, I think many-NUMA is highly questionable, so basing decisions on it is just not possible - so, regrding PRNG vs non-PRNG, for one NUMA node, well, it’s not quite clear yet. I think I need a little bit more testing - I say this because looking at the results, a lot of performance was still being gained in the step from DWCAS 9 to 10 - which means the backoff values were actually too low. Also, with PRNG basically means halving the DWCAS backoff value, so PRNG DWCAS 10 is the same as without DWCAS 5 - I think I need to run the test on the big machine again, but with a wider range of DWCAS values.
I can try such tests now though on an AWS instance which is half the size, since I’m sticking for now to one NUMA node, until I figure out more what’s going on with multiple nodes.
Here are the results with PRNG

The results are just another page in this tome of madness.
If you look at the equivelent with/without results for DWCAS 10, you have these two;
1 1 108466358,10846636,3882218,Lock-Free (DWCAS 10),67958891(0),40507467(1)
1 1 108837729,10883773,7286378,Lock-Free (DWCAS 10),80180100(2),28657629(3)
Fine. No worries there. In this particular test without seems a lot more fair but it’s a one-off; the next time I ran that same test on with-hyperthreading I saw this;
1 1 108644536,10864454,2586069,Lock-Free (DWCAS 10),45179134(2),63465402(3)
So basically the results are give-or-take identical. This is what we would expect.
However… go check the results for DWCAS 2, 5 and 9, on “with”.
Huge fucking dips in performance.
Which do not show up with hyperthreading turned off.
And these dips GO AWAY if you run with all four logical cores, rather than just two.
What the holy jesus christ good god I don’t even
1 1 1 1 93031939,4651597,16112911,Lock-Free (DWCAS 1000000),1001(0),93028936(1),1001(2),1001(3)
Cute, huh?
I’ve had a partial theory for this - basically, with backoff, one thread will successfully DWCAS, and then everyone else who also was trying then will fail. Those who failed backoff. The thread who succeeded immediately goes again, and again, and again… and so when the thread who have backed-off finally restart, the chances are the other thread who won earlier is already in the middle of an operation, and so they will fail again.
So here we see with a very large backoff value, one thread does all the work and the others almost nothing.
Question is though, how did they even get to do that little bit? because once they win an operation, they ought to become the dominating thread.
When a thread collides, it backs off. Each successive backoff doubles the wait period. In all the testing so far there’s a maximum of 10 backoffs.
I tried raising it to 30.

Interestin’.
Normal on 0 and 1, but above that and the loosing thread is consigned to backoff limbo.
So I’m getting the feeling there’s a balance here with backoff exponentiation. Too little, and you can’t climb rapidly enough to usefully long backoff periods (see the results for non-expoential backoff). Too much, and threads go into limbo.
And prolly optimal/near-optimal values vary by platform.
Scylla and Chablis anyone?
As subject.
A downside is that PRNG was being used to control the initial counter value for the next pointer in queue elements.
Now I have to use an atomic add, which will I think be the ONLY use of atomic add in the code base, and it’ll mean a bottleneck on that counter in the queue state.
Nothing else for it, except per-thread state, and I can’t justify per-thread state to avoid one atomic add.
Adding an ABA counter to each queue state doesn’t solve the problem because they all init to 0, so if we have elements bouncing between queues, all those queues to begin with are going to have similar ABA values, i.e. the problem isn’t fixed.
So I need to keep the PRNG code so I can init each per-queue ABA counter to a different value!
loling here :-)
At least all that PRNG code isn’t wasted!
ABsolutely fascenating. When placed in graphcal form, behaviours otherwise obscured in the mass of numbers become visible to the eye. This particular machine has dual sockets, with a total of 36 logical cores. That’s a strange number I suspect for a hypercube, and so I suspect some of the cores are disadvantaged with regard to the others when it comes to memory access - and so we see a slow core…
This of course was playing merry hell with the standard deviation numbers.
From my Core i5.
Just added per-data structure CAS/DWCAS backoff values. Removed the PRNG part of the backoff, but I think I said that earlier.
Been working on benchmark. Starting pretty much from scratch, but with the right ideas this time - btree for benchmarks, btree for results, abstraction layer for the locks.
The benchmark app has been a tar pit, because I’ve kept NOT starting from scratch, and so been mentally constrained in my thought my the code which already exists - which meant I never was able to break away from its design flaws.
I think the benchmark will be done, and done PROPERLY AT LAST FUCK ME in a week.
That thing has taken up an order of magnitude more time than it should have. Live and learn - tar pits.
Once benchmark is done, and I’ve sorted out power for the Pi and Ci20, I need to write a build and test system. I can’t keep manually making releases, it’s way too time consuming (and error prone).
Jesus, that reminds me, I’ll need to reinstall the Windows 8 trial to get the MSVC 2013 dev environment up… that whole process is so costly, in time and effort and mental agony. I literally dread doing it. It’s a plague upon the library and my personal happiness. I need to find a better way.
I have create a .onion endpoint for the site.
http://k263wv5uwidihxl4.onion:8080/
The blog doesn’t work as wordpress redirects itself to a URL it is configured to think of as its home, so it can’t exist on two URLs at the same time - it’s not using relative URLs all the time. Have to think about what to do about this.
I currently have the Ci20 board doing a brute-force on Tor .onion ‘domain names’ to give me a vanity name which starts with ‘liblfds’ and then is followed by a number.
Once I have this, I’ll move liblfds.org fully to the .onion site, and leave a placeholder on the liblfds.org domain, which explains where the site has gone.
I’ve been thinking quite a bit.
I’m currently (re-re-re-re-)writing the benchmark app.
That’s fine. I’ve gone back to a using a library for as much stuff as possible, because I find it easier to think and lay out code properly. When writing libraries these days, I look to avoid memory allocation - I have the user pass in allocations. Problem is when you come to something where the size of the allocation cannot reasonably be known - it’s the result of some complex work inside the library, so the user can’t know beforehand how much store to allocate.
One simple, inefficient solution is to ask the user to pass in worst-case allocations. For smaller allocations, where the worst-case can easily be calculated, this can be okay, and I’m pretty sure I can use this approach for the benchmark app, in its current form - although this is because the benchmark app makes no large per-NUMA node allocations; all the per-NUMA stuff can be allocated on the stack, in each benchmark thread, and so naturally (normally - OS decides but this is how Windows and Linux work) goes on the NUMA node for that thread.
If the benchmark did make large per-NUMA node allocations, the user would have to make them and hand them over…
…which is exactly how things are with the test app. This does make large per-NUMA node allocations.
In fact, what ends up emerging from all this is that the benchmark and test both become libaries, and the apps are just stdlib main()-type binaries which call the very high level benchmark/test call (singular), handing over the necessary memory, and getting results back.
This way embedded users who cannot malloc simply reserve heap space and pass it in.
(Abstraction layer for I/O, where the output is going into a line buffer, which is passed to a user provided callback - both the normal output and the gnuplots going to this interface, which on the Windows/Linux stuff means to stdout - the user pipes to disk).
This almost suggests test and benchmark become integral in the liblfds library - but this isn’t so, for two reasons; firstly, it makes the library bigger, where test and benchmark only need to run for particular reasons rather than being generally available and secondly, test requires a thread-starter/waiter abstraction and benchmark requires a thread-starter/waiter and topology abstraction.
The test app generally right now needs to be rewritten from scratch to be something really decent.
The benchmark app is now in its design really decent, but I’m at the point where I need to choose between a malloc or non-malloc approach.
I’ve been rewriting the topology code.
This code is partially an abstraction layer (and so that part must be friendly to users, easy to understand and implement). It has the job of representing the system processor topology in a btree, i.e. NUMA nodes, sockets, caches, physical cores, logical cores.
Under Linux, it’s easy.
Under Windows, OMG I don’t even
The problem is Windows has added into the mix a completely redundent, unnecessary and complicating concept called a “processor group”. Actual logical core IDs only go up to 64 - the largest number of logical cores in one processor group. So to identify a core, you must identify the processor group, too. Processor groups SPAN NUMA NODES, so the members are potentially HETEROGENEOUS.
Because the processor group must be specified, when you start using the Windows API for enumerating topology, you can have MULTIPLE entries for the SAME entity, where each entry lists a set of logical cores for the same processor group. So a given socket might have say four entries, all the logical procesors in processor group 0, then all those in group 1, etc.
Now, remember - I’m representing the topology in a btree. To link an element, I need in fact to know its full set of logical processors, so I can sort it to the correct location in the tree. In Windows, I can only KNOW that I know this BY FULLY ENUMERATING THE ENTIRE TOPOLOGY, i.e. I actually have to iterate over the entire topology for EVERYTHING I FIND, to ensure I have every logical processor which belongs to it.
The only reason for this madness is processor groups, which I’m going to utterly ignore, always (except I need to know them to be able to start threads on the logical cores I want).
I may be wrong, but I am really starting to think now that the extended MS API for getting system topology is actually broken - you can’t figure out the actual system topology from the information it gives you.
The problem is that processor groups can span NUMA nodes.
As such, processor groups can also span level three caches, because as a typical example on my Intel, the level 3 cache spans all logical processors in one socket, and that socket has one NUMA node. If a processor group can span NUMA nodes, it can span level three caches.
Information about NUMA nodes is returned with a single group affinity member - so a NUMA node which has more than one processor group will have more than one record coming back from the Windows topology API. However, NUMA nodes also have an ID in their info structure, so I can tie together these multiple records and know they’re the same NUMA node.
HOWEVER! cache records also only have a single group affinity member - BUT THEY HAVE NO UNIQUE ID.
So a level three cache with more than one processor group will return multiple records - but I will have no way of knowing they are records for the same cache.
That means I cannot actually know the topology of the system - I can’t properly know caches - and I care about that, because caches are fundamental to memory behaviour and so the selection of thread sets to benchmark performance.
I think the same issue may exist for level one and two caches. L1 and L2 are per physical processor, but a processor group is made up of logical cores. If a physical processor with two logical cores has one logical core in group 0 and the other in group 1, then the L1 and L2 caches for that physical processor also will be in two processor groups.
Oh, processor groups. What a fantastic bloody idea not.
I am not surprised this issue exists. The API to get topology info is appallingly complex and inadequately documented for its complexity. The processor group concept raised the complexity of the data by a power of two - and it’s complex enough to begin with.
I will need to think more, but if I can’t figure something more out, then the benchmark application cannot support processor groups on Windows due to flaws in the Windows topology information API.
Christ, it gets worse.

Windows (as I know) tries to minimize the number of processor groups, by making them as large as possible (up to their 64 core limit - 64 cores, 640kb RAM, you think they’d notice). However, naturally, if the number of logical cores in the system isn’t divisible by 64, you end up with uneven groups. (It also implies a processor group, which is the basic scheduling entity, can have multiple NUMA nodes, which implies scheduling is not actually NUMA aware, but only processor group aware - and that’s insane).
Intel bought out a 10 core CPU (bloody obvious, given the relatively slow rate of higher core numbers) with 20 logical cores, which induces this.
So there’s now a hotfix for Windows which modifies how processor groups are formed up, to ensure even groups. So some systems will have this, and some not…
