SOMEONE PLEASE HELP ME!!!

[geots]

I apologize for using uppercase in the header, but I have to get some sleep soon. Can anyone help me with MinkoChess 1.3. I had it set on 2 cpus, and it was all over the place while thinking, all the way from 1 thread to 4. I set it on 1 thread, and it jumps from 1 to 2 to 3 and back again to 1 core. Does anyone know the problem with it?


Thanks,

george

Haven't experienced any problems with it using 1CPU, but the behaviour you describe does happen when you use it with more than 1CPU.
Apparently, the way that some more recent engines operate using more than 1CPU, it is quite normal. Gaviota is another that you'll find does the same thing.

It maybe has to do when programs are using a separate thread for the input/output, but I have not noticed it with Stockfish have not tried that with two threads though. And it should not go back to one thread I think when set to two, at least that does not seem optimal.

Gaviota should never use more than 2 cores if it was set to use 2. It will oscillate from 1 to 2, getting closer to 2 as the thinking progresses, but it will never exceed that number. When a thread is idle, Gaviota makes it wait rather than spinning on the air doing nothing.
