How to test a 1-core engines in paralell on a multicore PC?

Thanks for the advice. My main purpose is to test different versions of my own engine against old versions. So I would think the issue you are raising shouldn't be a big concern, as long at the different versions use about the same amount of memory.

This sounds really interesting I'm looking forard to try it out. I hope it will support the winboard protocoll, cause my engine doesn't support UCI.

I intend for it to support both protocols when it's complete.

Not quite. If you use a total of 8 programs, and play 4 games at a time on 4 cores, then you should be OK. If you change the mix of opponents however, then performance issues come into play and can add some randomness to the results.

So, again, if you play 8 programs against each other for N rounds, all will be fine if the 8 programs remain the same. But if you replace just one, then that could impact other programs in the test and slow them down, and skew the results somewhat without your knowing...

Same thing would apply to 16 programs running on an 8-core box...

Hello Nathan,

I get a 404 error when following the link above.

Going through your web site in your signature is alright though.

Thanks for the improvements.

Later.
