Here's that WU run with AKv8b SSE4.1 , and stock cuda 6.05.

Same results as your AKv8 SSE3 Vs 6.06:

Thanks!
Will search another reproducible failures to collect them here.

Now VHAR WU:

Online and standalone results for CUDA app strongly similar again and both invalid versus CPU AK8 SSSE3x app result.

This is VHAR with AR~14, but it finishes OK and validates versus CPU in standalone. Online result the same as standalone one.

Again VHAR task, restarted under BOINC and non-overflowed.
Standalone testing w/o restarting gave strongly similar with online result and with CPU result too.

VLAR AR~0.15
Errors at CUDA mem copy, invalid results.
Wall clock execution time greater than for CPU app.

I don't think the timing comparison is meaningful, though the CUDA mem copy errors obviously show a problem with that.

Oops, will retest...
(thanx for spotting this early exit)

ADDON:report edited, now correct CPU run there.
(and reference on online result added)
