I don't know why I didn't think of this before...

With the recent discussion of the new Zen 3990x chip, the idea of using multiple threads per engine instance has come up.  I had considered this previously but had decided against it (I don't know why for sure).  But then I got to thinking about Custom Tasks last night.   Normally, unless you use scripts, Custom Task uses 1 engine and are pretty slow comparatively.  But if you cutback the number of engines and increase the thread count per engine... well, Custom Tasks will execute faster.

And I do A LOT of Custom Tasks.  It is my favorite method to expand the alternative base to make sure I don't overlook any shot (especially one that might come from my opponent).  Also, with fewer engines, I am able to increase the the cache size allocated to each engine, by at least an order of magnitude.  And I have always thought my IDeA engines used too little cache.

Now if I can just find $4000.00 to buy that 3990x (I am drooling over) <grin>.
