compile on Linux : which cpu arch ? #345

Closed tissatussa closed 2 years ago

tissatussa commented 3 years ago

i just compiled your newest Halogen v10.18.1 but the make process is not clear to me .. your readme does not state anything about the make process, so i guess just 'make' should do .. indeed it gives me a working binary of 1.7 Mb .. however, it shows 'POPCNT' while my notebook can do BMI2 and AVX2, which i prefer .. the Makefile shows bmi and avx are supported when doing 'make release' : it gives 5 binaries for 5 different ARCHs, which all work, but they have an extension '.exe' which points to a Windows executable, but these binaries DO run on Linux !? I tried 'make help' to see your compilation options / arguments but none are shown .. why is your Makefile not documented ?

KierenP commented 2 years ago

Sorry it's taken me so long to get to this.

As you've seen, your CPU is modern enough that it will run any arch that I support with make release. All versions of Halogen are the same, but may use different CPU instructions and hence some may run faster on certain hardware. You can run each and give Halogen the command bench to compare the speed (nps). Then you can use the one that is the fastest. Simply running make will likely produce the fastest compile.

That being said, the speed difference is likely to only be +/- 10% and is not significant enough to affect playing strength much so I wouldn't worry too much.

I hope you continue to enjoy using Halogen.

thanks for this explanation; it's clear, but not fully ..

That being said, the speed difference is likely to only be +/- 10% and is not significant enough to affect playing strength much so I wouldn't worry too much.

when different binary versions exist, the fastest is the best, so i wanted to know how to distinguish between them.

Simply running make will likely produce the fastest compile.

Likely ? Could your make script compare speeds with bench and so determine which binary type is optimal for the user CPU ?

KierenP commented 2 years ago

The way to distinguish between which exe is the fastest is to run each one and compare 'nodes per second' (nps) values. One way to do this is give the engine the command bench and observe the final nps value. Please let me know if you have any issues in doing this. It's a quick process and I don't think a script is necessary.

tissatussa commented 2 years ago

i compiled your latest v10.20.5 (source is git clone) and ran bench on all of them :

Halogen-x64-pext-avx2
27738055 nodes 1351000 nps

Halogen-x64-popcnt-avx2
27738055 nodes 1339000 nps

Halogen-x64-pext
27738055 nodes 1290000 nps

Halogen-x64-popcnt
27738055 nodes 1273000 nps

Halogen-x64-nopopcnt
27738055 nodes 1271000 nps

in the makefile i adjusted the output file names to distiguish : '-default.exe' and '-pgo.exe' are added :

default:
    $(CC) $(CFLAGS) $(SRC) $(LIBS) $(POPCNTFLAGS) -o $(EXE)-default.exe

pgo:
    rm -f *.gcda
    $(CC) -fprofile-generate $(PGOFLAGS) $(SRC) $(LIBS) $(POPCNTFLAGS) -o $(EXE)-pgo.exe
    ./$(EXE)-pgo.exe bench 12
    $(CC) -fprofile-use $(PGOFLAGS) $(SRC) $(LIBS) $(POPCNTFLAGS) -o $(EXE)-pgo.exe
    rm -f *.gcda

then bench gives this result :

Halogen-default.exe
27738055 nodes 2200000 nps

Halogen-pgo.exe
27738055 nodes 2336000 nps

so, the 5 release versions are considerably slower then the other 2 !? the pgo binary is the fastest on my CPU.

KierenP commented 2 years ago

I'm surprised the release versions are much slower than the other two, usually the difference is not that great. Will investigate further. In the meantime enjoy using Halogen.

tissatussa commented 2 years ago

tnx .. glad to help .. i'm also surprised of the nps results .. since my new laptop, which can do avx2 and bmi2 (i don't know what this really means) i read those archs should be fastest ..

tissatussa commented 2 years ago

maybe the real speed of avx2 / bmi2 also depends on the type of C functions you use to get optimal performance ? I'm not into that.

KierenP commented 2 years ago

Results on my computer:

Halogen-default.exe
27738055 nodes 3468000 nps

Halogen-pgo.exe
27738055 nodes 3679000 nps

Halogen-x64-pext-avx2
27738055 nodes 2760000 nps

Halogen-x64-popcnt-avx2
27738055 nodes 3307000 nps

Halogen-x64-pext
27738055 nodes 2544000 nps

Halogen-x64-popcnt
27738055 nodes 2883000 nps

Halogen-x64-nopopcnt
27738055 nodes 2940000 nps

I'm not surprised the default and pgo compiles are the fastest. Those use a compiler flag that uses the best instructions for your cpu so they are likely using avx2, bmi as well as others. What version of gcc are you using?

tissatussa commented 2 years ago

$ gcc --version gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

KierenP commented 2 years ago

Ok that's relatively modern. I don't know why the static (make release) compiles for you are so much slower than the native compiles.
