It is on the github now. I implement 4 bitmaps but on global memory, it is still 16MB for each bitmaps. I will enlarge it later. Currently I use 4*8KB = 32KB local memory for bitmaps. I find performance decrease in 4 bitmaps case. It may due to more work(compute for bitmaps) in kernel. But for hashes in local memory case, it really need optimization. Here is the result: 1: guesses: 0 time: 0:00:01:36 0.00% c/s: 1752M 1000: guesses: 0 time: 0:00:01:40 0.00% c/s: 1682G 1M: guesses: 0 time: 0:00:02:01 0.00% c/s: 648120G Thanks myrice
