Implement proper stop signalling from root node

mirror of https://github.com/opelly27/Stockfish.git synced 2026-05-20 06:17:49 +00:00

Previous behavior was to wait on all nodes to finish their search on their own TM and aggregate to root node via a blocking MPI_Allreduce call. This seems to be problematic.

In this commit a proper non-blocking signalling barrier was implemented to use TM from root node to control the cluster search, and disable TM on all non-root nodes.

Also includes some cosmetic fix to the nodes/NPS display.
