Stockfish 180813 x64 4CPU tournament (cancelled)
Re: Stockfish 180813 x64 4CPU tournament
I have to abort this tournament. ChessGUI is not sending the threads parameters correctly to the engines. I will start this again under Shredder GUI which is bullet-proof, and cancel this one.
Re: Stockfish 180813 x64 4CPU tournament (cancelled)
Same thing under Shredder GUI. The engine config file reads
[ENGINE]
Name=Houdini 3 x64 4CPU
Author=Robert Houdart
Filename=C:\Program Files\Houdini 3 Chess\Houdini_3_Standard_x64.exe
[OPTIONS]
Threads=4
GaviotaTbPath=C:\gtb
Yet Houdini is using only 3 cores Bizarre. So I was wrong in blaming ChessGUI for this, it seems it is Houdini. Maybe I'll try the Pro exe. Come to think if it, I've had this problem with Houdini before. It certainly explains Houdini's sub-par performance in the 48 games that I did play.

The Houdini Pro exe is the same. I give up on it. An incompatibility with AMD perhaps.

Maybe it is an incompatibility. It is using 4 cores for me (Xeon cpus).Ray wrote:The Houdini Pro exe is the same. I give up on it. An incompatibility with AMD perhaps.
