概要
Stockfish17のAffineTransformとAffineTransformSpraseInputを移植してきました。探索depth固定でのbenchコマンドのノード数も変化しておらず(AVX2やAVX-512では)、正しく動作しているようです。
SSE4.2以下や、NEONについてはこちらでは検証できておりません。
ベンチマーク
R9-7945HXでAVX-512有効の場合、標準NNUEでは移植してきた
AffineTransformを使うことで9.2%、さらにAffineTransformSparseInputを使うことで10.7%ほどNPSが向上することが確認できました。ただし、
halfkp_512x2-8-64やhalfkp_512x2-8-96ではNPSの低下が確認されています。
