Scenario 98

Creator John McLeod VII
When 28 Apr 2013
Description Insufficient work to keep all CPUs busy because of a high priority long running single CPU task and a multi CPU task. The single CPU task should be running, but it would be really nice if work fetch could find some work from a single CPU project somehow. NOTE: The last time I checked, if the multi CPU task was deleted, another of the same would be downloaded. This may have changed as SETI has a very high resource share.

OK, the simulation is not running the CPDN task in high priority. The real machine is running the CPDN task in high priority as it will finish after the deadline. Test4Theory is not running on the real machine as it is not yet high priority. There is a problem is the simulator does not match the behavior of the real machine.

It appears that there is a bug in the client simulator. It appears that the client simulator has both a single CPU task and a dual CPU task running on a 2 CPU system at the same time.
