Scalability of thread parallelization using OpenMP on (a) K computer (8 cores/node) and (b) TSUBAME (12 cores/node, hyper threading enabled). 1ACB chain E and 1ACB chain I was used for docking. Elapsed time was measured from the mean of 30 docking processes. The right area of the dashed line shows speedup by activating hyper threading.
