Same tests done today with HT ON!
With same engines + Stockfish prepare builds for TCEC9 Final ..i get two compiles from Kiran ,one normal ,one with numa
Marco had put the sources on Fishcooking so i have also compile these two..also to compare speed
Same thing..all data in spreadsheet updated ,scroll down to the date 31-10-2016

Stockfish have still work to do! Numa doesn't work..
asmFish ,Cfish & BrainFish are numa-aware and can use 88threads @100%

Here benches from 9 engines!
6 off them where Stockfish versions without CounterMovesHistory(CMH) ,3 from Marco who are/where in testing in Testframe.
and 3 versions from mstembera who also want i check them out..
2 last versions from asmFish & pedantfish + i made a compile from Cfish with last source.
Each engine get 10 runs ..so that's 90 times copy & paste these 3 command lines :)
All data under i have put again in spreadsheet to have a nice compare..just scroll down to the date 01-09-2016 for this new data:
https://docs.google.com/spreadsheets/d/156Iztrz4erBxTntb6A9-4hCNAtLyazdBBh8zGy0RApE/edit#gid=0
some info is in the spreadsheet..
With the first version from Marco, i compiled Stockfish 300816 64 BMI2_CMH and let him play for my list,and he's doing very well..

Last evening again a new run with some benches from last asmFish 2016-08-25 ,last Dev.Stockfish 270816 ,Hannibal 1.7 & Andscacs 0.872b
Just scroll down to the date 28-08-2016 for this last data that i put in this spreadsheet:
https://docs.google.com/spreadsheets/d/156Iztrz4erBxTntb6A9-4hCNAtLyazdBBh8zGy0RApE/edit#gid=0
Scaling from asmFish is just great ,getting from 22 to 44cores 103,79%!! and Stockfish is hanging around only 60%..
Some info: later i will have the chance to run on this system ;)

Did run some benches last evening with last version from asmFish 2016-07-26 ,Stockfish 020816 ,Texel 1.06 & Hannibal 1.6.58
I have put data in spreadsheet + some explenations: (scroll down to date 07-08-2016)
https://docs.google.com/spreadsheets/d/156Iztrz4erBxTntb6A9-4hCNAtLyazdBBh8zGy0RApE/edit#gid=0
Conclusion : The engine with working Numa-aware code will win TCEC9 final when using a 44cores system!
when you see Stockfish & Komodo so close in strenght in these LTC games..look out for Houdini 5 dev. ,it has Numa-aware..Robert has only
to update his Numa code so that it works well with more cores..will be dangerous when get in Final! Is it possible?! ;)
Or will Stockfish & Komodo wake up and include Numa-aware ..

And yes..with a bmi2 compile and 72cores i pass the 200Million nodes/s. with this position!
At the moment it's playing on my 3systems..and start as first engine on my 3computers..for sure with 1core,it was already first,now even bigger jump!!

Yesterday evening i run some tests with asmFish NumaTest_base
It was after testing that i find out it was only a 64cores version ,so it was normal that 72cores gives nothing more!
Also this was a base version..not a pocnt or even a bmi2 compile who would be even faster..but the gain is very clear higher thanks to Numa-aware!
So,have already two engines where Numa-aware works how it should be..Texel & asmFish ..who is next ;)
To see all these cores awake and running @100% it takes 1sec.!! very fast..
First bench was just selecting cores and use go depth 25

And this was done with only base version 64cores..so i think with bmi2 version and using 72cores it will be easy above 200Million nodes/sec.
with this position!
Now this morning i see that Mohammed Li has updated asmFish 2016-07-02 with 256cores now!

Sometimes programmers listen to testers and it's nice to see that i get response on that and bite in this Numa aware thing!
Thanks to Peter ,Mikael & Moh who trying things out with tools or changing code in there engine that we have now a working engine with Numa aware!

So Crafty 25.0.1 Numa also doesn't work like it should work on a 4cpu system?
William show me Cinebench..when you start it..it shows directly it has 72cores and bench use them all 4 x 18cores..4cpu's 100%!!

Again same happen ,till 2cpu's everything goes well ..more cores using cpu3 & cpu4 doesn't give more nodes/sec.anymore and system slowdown!?
Needs to be NUMA aware if we want chessengines using these 4sockets systems optimal!
A little check from 18cores till 36cores (1cpu till 2cpu's) gives me 89,30% speed gain in nodes/sec. ,so same as other system who gives me 90%!!

Next test done on 14-06-2016
sytem:Xeon E7-8890 v4 4x24cores=96cores/192threads
I have contacted a few people after first test with the question if they have more idea's that i can test out
on this extreme system..i don't think we have many times the possibility to run some benches
on a 96cores/192threads system.
I get a e-mail from Mikael with later on a source from Stockfish without CounterMoveHistory!!
And i made a compile from it and ready to run some benches..
A other person asked me can you also run with 44cores as the final from TCEC9 will run a system
with 44cores..so i did..with the thinking it will be 2x22cores ,so tested also with 22cores
with the knowing that this system each cpu has 24cores..so 2cores different can show some
difference in nodes/s ,because the results before that where not going well after 24cores..but!
WoW what a difference..that is what i want to see,with a great scaling till 48cores now and
with much higher nodes/sec.
Just check this:

Compare the results from first test..here all numbers are much higher and scaling nice till 48cores!
Just enough for TCEC9 final system ,see from 22cores to 44cores..almost dubble nodes/sec.!!
Test before give highest nodes/sec. with 64cores -> 72Million nodes/s ..now with 48cores -> 96Million nodes/s!!
And this thanks to Mikael with one single change in source ..who will do better ;)
Then we can go for next problem..how to handle cpu3 & cpu4 a extra 48cores who do nothing now?!
Imagine he continue scalling like these first 48cores!
Do i have only to count on Mikael ? ;)
For sure bring this compile to TCEC9 ..maybe i will try to contact Anton ,that he just try and see
the difference in speed on there final system..
-----------------------------------------------------------------------
Again i had some free time left on the system..so did some more tests:
Used here different time use..but they are same as above..it shows every time the same big
difference in nodes/sec. (proves for me it works very well)

Today i get a chance to test some chess benches on a Xeon E7-8890 v4 with 4 sockets!!
means 4cpu's x 24cores = 96cores or 192threads!
Operating system : Windows Server 2012 R2
1cpu = $7174 http://ark.intel.com/nl/products/family/93797/Intel-Xeon-Processor-E7-v4-Family
It was my first experience..and after a little searching how to transfer files ,copy & paste data i was ready to run some benches..
Engines that i used :
I compiled Stockfish with last source and set it to 256cores
I compiled DON 100616 also last source with 256cores
I get Komodo 1656 with 200cores ,Thanks to Mark & Larry!
Houdini 4 Pro 4 B only 32cores ,but has Numa (later more)
I had put a request on Fishcooking..and i getting some good info about how to bench best..so thanks for this information!
Also DON programmer Ehsan was kind enough to help me out..
Will come back during these tests..
I had prepare myself with all these Bench commands and i wanted do as many possible benches in the time i get on this
great system..so i choose to use a fix time for every bench ..or with some engines i use go depth 24 ,go depth 26 ..depending
how long it takes..
With my first contact had William run some tests..and i see it didn't work how i liked to see with these 192threads
Also programmers would like to see results with HyperThreading OFF ..so i decided to run benches with HT Off!
Lucky i told this William the day before ,so that he this morning can boot with HT Off (takes long time..)
For explenation..it will be clear ,i put some between these results.. so you need to scroll a lot with these few tests i did ;)
Let me start first with Stockfish:
Some people propose me to use 8Gb hash and i did this in every test..at the end i had some time left and wanted to see
what engines do with different Hash.
So..first you see bench 8192 8 2000 default time = 8192 Hash using 8cores and 2sec. for each position x 37
Stockfish has 37 positions into his bench test.
You can see Time is almost and always same.. cores i used where : 8,16,24,32,48,64,80 en 96cores
The result with different Hash i have put inbetween afterwards with the same total cores.

It was clearly using 2000 default time was better with Hash=1024
Now something Important!!
While these Nodes/sec. looking great i see a big problem during these tests..
But there is also good news!
First problem..till 24cores everything goes fast..above 24cores and the more cores i add ,how slower the test begins to go
even at the end you see almost same time used..but that's not true..the max.cores i see running where 48cores?
and you can see the nodes/sec. don't change so much anymore when using 64,80 and 96cores then when you compare from 8cores till 24cores..so when selected 64,80 or 96cores ,i see 48cores running?
With 32cores you will say,they go nice higher..but it's already lower then it should be!
So the good news is..it's not SMP problem ,but NUMA is needed when running a system with multi Intel cpu's!!
Why i say Intel ..because from AMD i don't know it and not test it yet..
1cpu = 24cores..everything till there goes great
2cpu's or more need NUMA!!
Next DON engine from Ehsan:
With DON i had to use 2000 movetime in place off 2000 default time to get a fix time bench!
Same thing here..till 48cores ,nodes/sec. goes nice up and then almost no change anymore
Total time same..but goes slower and slower with more cores to finish the test..

Komodo has already a slowdown in nodes/sec. gain after 16cores.. some work to do!
And as last Houdini:
When i see the problems with slowdown and not using all cores ,i said yes Houdini has Numa
but when i check ,it handle only 32cores ..but i say okay maybe i can see a little difference when i go from
24cores to 32cores
Used same bench commands as Komodo
Houdini go depth 24 H=8192 C=8

Hash=1024 would give again higher nodes/sec. but i had a problem when i want to set 32cores
Till i check and see this:
Houdini 4 Pro x64
(c) 2013 Robert Houdart
info string 48 processor(s) found, POPCNT available
info string NUMA configuration with 4 node(s), offset 0
info string 128 MB Hash
info string No valid license found
setoption name threads value 32
setoption name threads value 24
info string 24 threads used
setoption name threads value 32
I have a Licensed from all Houdini's i have..but have not thought when i copy the engine to a other computer
that it will be No valid..anymore
Also this "info string 32 threads used" came not when i press Enter..so i re-start Houdini every time ,and time by time it
get this "info string 32 threads used" i did the run then..
But it was after that ,that i say something is not right..and see later on that my version from Houdini was Not licensed anymore
..so i can say that these results are maybe not valid as i know Houdini will not play at full strenght.
Now i'm hoping that Robert with his new coming Houdini 5 will put enough cores as he has Numa!
It will be interesting to test this further out..and i think there will be more people to have a system with more then 1cpu..
So the chess programmers have to think to include NUMA in there chess engines if we want to profit and gain more nodes/sec.
in our systems!!
Again a big thanks to William H. to let me run these tests! It's a pleasure to meet you ;)
Thanks to the programmers for the info and compiles that gives me a chance to run these tests,even i coudn't really use all these cores
but now we know what is needed..Numa!
Ipman.
PS: Did make this little report after testing..so it's possible i have to adjust some off my explenations later on..
A little video link to the system i was using: Is removed..
