Subject: CUDA vs Test Suite [was: OpenCL vs Test Suite]

I had a look at CUDA. The combined -gpu target I made seems to work just
fine, I get both CUDA and OpenCL formats at once.

Enclosed is yet another version of jtrts.dat for Test Suite, combining
support for OpenCL as well as a couple of the CUDA formats (the SHA-2
ones will be added later, for non-GPU too). Usage:

./jtrts.pl opencl  (all opencl formats)
./jtrts.pl cuda    (all cuda formats)
./jtrts.pl gpu     (all opencl and cuda formats)
./jtrts.pl md5 cryptmd5-opencl cuda-cryptmd5  (any number of specific
formats)

I have some problem with CUDA:

GTX280 and 9600GT:
Benchmarking: cuda-mscash2 [GPU]... FAILED (valid)
Benchmarking: cuda-mscash len(pass)=8, len(salt)=13 []... FAILED
(get_hash[0](0))

9600GT only:
cuda-cryptmd5 failed (get_hash[2](0))

The 9600GT might just be too weak a card, or should it work? I might
have some time to debug these problems later, I presume it works for you.
