I have two Linux x86_64 systems, both running the same release of Linux Mint17.

One of them has run a few WUProp jobs, and each of these has consumed ~19 CPU seconds in the 6-hour elapsed run.

However, the other system (which does have an AMD GPU card running tasks) is running the WUProp task at ~60% CPU continuously - which is hardly "non-CPU-intensive.

Any ideas as to why this is occurring - and what I can to about it?
