Message 736034 - Posted: 8 Apr 2008, 2:37:01 UTC

Why is it that one of my two machines receives tasks that are huge taking 15-30 hrs to complete and the other one receives small tasks 2-6 hrs to finish. The first computer is slow 930mhz where as the second is a 3.0 ghz. Can this be controlled? Why does the slower 930mhz never receive a high priority wu.

If I am understanding correctly, the 933MHz system gets 15-30 hr tasks while the 3GHz gets 2-6 hr tasks? That would simply be the difference in hardware. The faster the CPU, the quicker it takes to complete a workunit.


Why does the slower 930mhz never receive a high priority wu.


There are no explicit "high priority" workunits. "High priority" is simply a friendlier name for Earliest Deadline First, meaning that BOINC feels there may be a risk in completing the workunit before the deadline, so it switches its method of crunching workunits from FIFO (first in, first out in order of download) to whichever has the earliest deadline.

Note that "high priority" mode does not crunch any faster than standard mode.

Ah, there are no stupid questions*. Now you know.

Actually, I've heard it said that there really are stupid questions.

Those are the ones you choose not to ask...
