:confused:

Is there an article or how-to somewhere which explains exactly how to achieve simultaneous analysis of >1 game ? The article referenced below at ChessOK does not seem to provide those details or a link to where the steps may be found.

Many thanks .. :grin:

ChessOK's wording is a little imprecise. The illustration is of simultaneous analysis of three positions from three different games and is easy to implement. If your interest is in analysing games, then I think only one game at a time is possible.

Many thanks for the prompt response. Would you be so kind as to give me a step-by-step on how to implement the 'simultaneous analysis of three positions from three different games' - this is purely out of interest. And yes only interested in analysing games - :lol: - my brain has difficulty with ONE game at a time !!

The manual provides a step-by-step instruction. Simply apply it in turn to three separate games. Remember you are limited by the total number of threads you have available and you will not be able to use the same instance of an engine more than once. If you want to use a common engine you can create additional instances, perhaps by placing copies in separate folders.

In the Project Properties you can set the CPU usage.  This is very handy when you are having more than 1 project active simultaneously.  It allows you to set how much CPU time percentage wise to each project.  For example, at this very moment, I am analyzing 2 projects, one with CPU usage set to 30 and one with it set to 70.  This gives priority to one project, but still keeps the other one going at a good clip.  I usually run 12 threads of engines, so there is plenty for each project to utilize.

I know some folks that set one project to 99 and another to 1, this allows 1 project to be very dominant in CPU usage, but allows the other project to get some time during minimax events in the primary project.  Kind of sets a background project....

Checked the manual - couldnt find the relevant section so for now I'll put this on the backburner. I am way behind on my games at ICCF so will return to the topic with a closer reading of the manual in a few weeks.

Thanks dickie, pawnslinger for your comments, advice, suggestions .. :smile:

Section 8 - Infinite Analysis, and following pages.

Believe me... the Project Properties dialog box is something that you should know backwards and forwards.  Even if you can't find it in the manual, pull it up and study it on your own.  It has 2 tabs and is stuffed with parameters you would hugely benefit from knowing how to use.  The CPU Usage is one of the primary project parameters.  I deal with it routinely, without even thinking about it.  One can't tune a automobile without knowing what spark plugs are!

Thank you pawnslinger, I have learned something new.
