Patrick, it would do calculations if it moved 0s and 1s in CPU
Machine is dedicated cruncher 24/7. On screenshot you can see that instead of doing calculations, it did not do anything (
from CPU point of view) for 9 hours. And at the same time on another core, it crunched less-memory-expensive WUs with much less difference in runtime/cputime.
PS: at this moment WU is still crunching,
cputime = 10:21
runtime = 19:17
