It actually takes like 3.5 hours vs CUDA's 26 seconds. Something is not
right.
form=xsha512-cuda guesses: 1468 time: 0:00:00:13 [PASSED]
.pot CHK:xsha512-cuda guesses: 1468 time: 0:00:00:13 [PASSED]
form=xsha512-opencl guesses: 1050 time: 0:01:47:10 [PASSED]
The .pot file check will likely take 1:47 also, so totalling 3:34.
However, I now removed the "unreliable" tag for that format too.
