Igel author himself is renting out machines to do it.

Yes, I am renting hardware to train Igel net, and the sad part is that I need to sacrifice my CCRL testing capacity as the training is so time (and money) consuming.

I wish Andrew we can re-purpose OpenBench nodes for this

Hello OliverBr, I am having problems running igel on an AMD EPYC 7502P 32-Core Processor with Linux: ch@AR161:~/engines/igel/src$ make g++ -Wall -std=c++17 -mpopcnt -pthread -msse -msse2 -msse3 -msse4.1 -mavx2 -O3 -march=native -flto *.cpp nnue/*.cpp nnue/features/*.cpp -DNDEBUG -DEVAL_NNUE=1 -D_BTY...

Thanks for testing Igel!

Can you provide a pure popcount version without AVX?

Preferably a SSE4.1-popcnt one, well for Xeon X5670?
regards

Hello peter,

Will provide you a gcc compile for your CPU by the EOD.

Nice improvement! A first quick test shows that Igel is now among top 10 programs.

Thanks Torsten.
