Commit ID ebc563059c5fc103ca6d79edb04bb6d5f182eaf5
Author Joost VandeVondele
Date 2017-06-17 02:20:01 UTC
Call TT.new_search() earlier. TT.new_search() was being called by mainThread in Thread::search(). However, mainThread is the last to start searching, and helper threads could reach a measured rootDepth 10 (on 64 cores) before mainThread increments the TT generation. Fixed by moving the call to MaintThread::search() before helper threads start searching. No functional change. Closes #1134
