If you have a look in opencl_pbkdf2_hmac_sha1.h you'll see the 3
structs. You'll probably need to do struct.pack() to create one of
each of those structures.
So for example, I'd construct it with something like this:
password_host_buffer = "".join([ struct.pack("=I65s", len(plaintext),
plaintext) for plaintext in plaintexts ])
password_dev_buffer = cl.Buffer(ctx, mf.READ_ONLY | mf.COPY_HOST_PTR,
hostbuf=password_host_buffer)

Michael
