Initialize shared continuation history once per NUMA node Worker::clear partitioned correctionHistory and pawnHistory by NUMA thread index, but then filled the shared continuationHistory from every worker. Since continuationHistory is constant-size and shared only within a NUMA node, have only thread 0 of each node initialize it closes https://github.com/official-stockfish/Stockfish/pull/7069 No functional change Co-authored-by: ppigazzini <pasquale.pigazzini@gmail.com>
