Dear list users: I happened to test duration times of calculating the system I'm investigating against number of pools used. There are totally 36 k points. But the results surprised me quite a lot.
no pool: 6m21.02s CPU time, 6m45.88s wall time 2 pools: 7m19.39s CPU time, 7m38.99s wall time 4 pools: 11m59.09s CPU time, 12m14.66s wall time 8 pools: 21m28.77s CPU time, 21m38.71s wall time The machine I'm using is an AMD box with 2 quad core shanghai. Is my understanding of usage of pool wrong? Huiqun Zhou @Nanjing University, China
