Hi Paolo,

just a little heads up. I've implemented AES using the coarse-grained
approach (one thread for each AES block of 128 bits) and have obtained
the following kernel-performance (this is the theoretical megabit
performance of the kernel, just to compare it to the old version.
Detailed benchmarks using the whole engine will follow as soon as all
the modes and OpenCL have been implemented as well):

8600 GT: after: 7651 Mb/s before: 2668 Mb/s
GTX 295: after: 44.701 Mb/s before: 18.408 Mb/s

Greetings,
Jojo

Hi Johannes,
I find this test interesting, I'm waiting to see a completed one for
make a comment.
