Test Conditions

NCM uses dual CPU Xeon E5-2670 16 core dedicated servers to perform its dev build tests. Each physical server plays 8 games concurrently. Hash is set to 128. Threads is set to 2 so that each position during the test is evaluated using two processor cores.

Time controls are set to 30+0.3 and scaled periodically by comparing the server's Stockfish bench score to 1600k nps.
