Sorry for late replay. 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:

guesses: 0  time: 0:00:01:36 0.00%  c/s: 1752M

guesses: 0  time: 0:00:01:40 0.00%  c/s: 1682G

guesses: 0  time: 0:00:02:01 0.00%  c/s: 648120G
