myrice -

Here's an easy task for you: please add support for raw SHA-512 in CUDA
and OpenCL as well.  This should be easy given your existing code for
XSHA512.  Indeed, the expected performance is similar to that of XSHA512
in the single-salt case.

Meanwhile, oclHashcat-plus 0.08 got support for these two.  The posted
speeds are 70M to 76M c/s on both GTX 570 1600 MHz and 7970 (yes, these
should be directly comparable to those we're getting on bull).  So your
70M c/s on GTX 580 was a pretty good speed, in fact.  Now you just need
to achieve it on the cards in bull as well. :-)

Thanks,

Alexander
