What happened with cfish nodes/second

[Denzwell]

Cfish : Src of 2018/02/15

Total time (ms) : 4365 Nodes searched : 5006365 Nodes/second : 1 146 933

Stockfish 9

Total time (ms) : 2445 Nodes searched : 5006365 Nodes/second : 2 047 593

[syzygy1]

Something is wrong with your compile.

[Denzwell]

Ok i see the problem the makefile has changed since. You have added other flags. Example - D__USE_MINGW_ANSI_STDIO = 1

[Denzwell]

Ok when i make compile without this flag -D__USE_MINGW_ANSI_STDIO = 1 there are a lot of Warning but nodes/second is very high (It is ok) .

This flag produces a decrease of nodes/second. The speed is divided by two

I use x86_64-w64-mingw32 and gcc version 7.2.0

[ChessMan3]

I have the same in command prompt but i ignore it - speed is OK in GUI or Build Tester.

[syzygy1]

Aha, that is bad. I'll remove the flag later today and I'll just switch off the warnings. Thanks for investigating!

[ChessMan3]

I revert "Fix warning when compiling with MinGW." and there are no warnings with comp=mingw. I have warnings only with comp=gcc, MinGW 7.3.0/7.2.0. Also lto = yes is not working with comp=mingw (i don't see -flto in output and exe size is smaller). BTW: Cfish is a bit faster without "Fix warning when compiling with MinGW.", but it can be a noise.

The speed loss should be undone now.

I don't think I can do much about LTO not working with MinGW on Windows (it works with MinGW on Linux).

[CoffeeOne]

I tested latest Cfish sources (as of now, last commit 2018-02-15). With single thread benches I found out, that lto = yes, extra = yes and activation of black magic in config.h works best for me. PCs: Xeon 40 Core, Opteron 64 Core (both are non bmi2) under Windows msys2 gcc7.3: Opteron: bench 1024 64 24 (10 runs) avg: 57.7 MN/s Xeon: bench 1024 80 24 (10 runs) avg: 68.0 MN/s

But what was surprising, I made also a multi-core on Opteron run with a compilation with extra = no, and it was only 52.0 MN/s on 10 runs 1024 64 24

When writing that, I saw that @syzygy1 again updated Cfish, I have to redo the benches, arrrggghhhhh Please note also that those multi-thread runs with so many threads are very noisy.

[ChessMan3]

LTO is working with comp=mingw if add -flto manually, let say here: "CFLAGS += -flto -Wall -std=c11 $(EXTRACFLAGS)" or in another place.

[CoffeeOne]

@ChessMan3 I tried only to compile with COMP=gcc with msys2.

[mausalimi]

i fail to build a x86 binary.

make profile-build ARCH=x86-32-modern COMP=mingw COMPCXX=i686-w64-mingw32-g++

Config: debug: 'no' optimize: 'yes' arch: 'x86_64' bits: '64' prefetch: 'yes' popcnt: 'yes' sse: 'yes' pext: 'no' Flags: CC: gcc CFLAGS: -Wall -std=c11 -Wextra -Wshadow -DNDEBUG -O3 -DIS_64BIT -msse -msse3 -mpopcnt -DUSE_POPCNT -march=native -DNUMA LDFLAGS: -lm

this then builds 64 bit here. what am i doing wrong?

[syzygy1]

The Makefile was broken for 32-bit builds. It should work now.

[syzygy1]

@ChessMan3 To compile with LTO, add lto=yes to the make command. So "make profile-build lto=yes".

[ChessMan3]

@syzygy1 thanks it is working well, same as before for comp=gcc and lto=yes. But lto=yes still not working for comp=mingw on Windows. Can you change "ifeq ($(comp),$(filter $(comp),gcc clang))" to "ifeq ($(comp),$(filter $(comp),gcc mingw clang))"? With this changes lto=yes is working with "make profile-build ARCH=x86-32 COMP=mingw"

ok, i'm a complete idiot. the correct make line for a x64 build is something like

make profile-build ARCH=x86-64-modern COMP=mingw COMPCC=x86_64-w64-mingw32-gcc

and for x86 it would be

make profile-build ARCH=x86-32 COMP=mingw COMPCC=i686-w64-mingw32-gcc
