X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=3b7c1a17e4c1214ca84ebb27fde28ae2ac132396;ds=sidebyside

Increase maximum number of threads

a single Xeon Phi can present itself as a single numa node with up to 288 threads (4 threads per hardware core).
Tested to work as expected with a Xeon Phi CPU 7230 up to 256 threads.

No functional change

Closes #1045
