Just to clarify: you're aware that we already support this on CPU (in
the bleeding-jumbo branch), and you want us to also support it on GPU
(in OpenCL), right?
On a 16-core machine:
$ OMP_NUM_THREADS=16 ./john -te -form=bitcoin
Will run 16 OpenMP threads
Benchmarking: Bitcoin [SHA256 AES 32/64]... (16xOMP) DONE
Raw: 125 c/s real, 7.8 c/s virtual
Indeed, there's lots of room for optimization, and we do need to have
the OpenCL-enabled format too.
