I have 2 computers. My home pc only has one processor, and that seems fine. My work pc has 2 processors. Originally both were running. Now only one gets run and the other has a status of \'Preempted\'. On my preferences I state to use at most 2 processors. What else could it be?

It looks to me like your system used to have hyper-threading enabled in the BIOS but has been rebooted with the option disabled, Stuart.

Result id 148186 stopped trickling on 12th October, and since then the seconds per timestep for <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/trickle.php?resultid=148184">result id 148184</a> has been going steadily down. CPDN will calculate 2 models about 15% faster with HT enabled.

You can quickly tell if HT is enabled or disabled by running task manager and clicking on the performance tab. If you've got 2 graphs displayed in the CPU usage history section HT is enabled, otherwise it's disabled.

Wouldn't the host status page say "Number of CPUs : 1" then?


Could be a "Venue" problem too, if @Home is set to use only 1 CPU and the Xeon used to be @Work but switched to @Home for some reason (the Venue setting sometimes gets lost)

In this case it would be safer to set it to 2 CPUs @Home too
