Subject: Re: async key transfers to GPU

Here are the result with 2 streams. Stream #1 memcpyH2D first half of
keys in set_key(). Stream #2 memcpyH2D second half of keys in
beginning of crypt_all(). Then I split xsha512 kernel into 2 with 2

Here is the profiler data:

There is only 4.2% overlap. memcpyH2D is 2 time slow on bull. And two
xsha512 kernels execution time are slight slow than one.

So avoid data copy and generate password on GPU would be very helpful.
It is time for me working it out quickly.
