The CPU is running 2 WUs at 100% CPU and all is fine! The work buffer has suddenly increased, as if the computation time was miscalculated. The CPU is obviously idling, as no heat is produced, and the fan is at low speed. I'll check again, and the "progress time" appear as if the computation run at full speed.

The computation time is very long; can these WU:s have been stuck in some kind of loop?

EDIT:
No, sorry, the computer was in error. It seems to be running in a normal mode now.
