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

Same results as your AKv8 SSE3  Vs 6.06:

Result      : Weakly similar.

Bench file attached.  Ignore that I broke some Init_data.xml values while experimenting with something else ... no effect on (the lack of) validity of the 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.

============
AK_v8_win_SSSE3x.exe -verb -st / 23no08ad.15915.22976.9.8.127.wu :
Started at  : 19:48:10.591
Ended at    : 19:48:55.394
     44.772 secs Elapsed
     44.757 secs CPU time
...
No heartbeat from core client for 30 sec - exiting
...

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)

[edit] found 2 more of them, same AR, nearly same results ... stock cuda on both with triplet count: 31[/edit]
