Re: For HGM: Engine priority under Winboard/Polyglot

My engine is programmed in such a way that dead time, that will always occur in a MP search, is given back to the operating system. This is a design decision. I hate it when my system becomes sluggish, thats why I do it this way. I guess my engine is therefore more sensitive to scheduling priority than most others.

Of course it would be better to keep the number of running processes as low as possible, but with current operating systems most processes are really needed, and you just can't terminate them without crippling things.

Changing the priority to normal totally solved my problem, so I'm very happy now! It's a pity that I only found out what the problem is after a couple of years of using Winboard.
