I have a single SoB workunit in my queue, which otherwise consists of hundreds of SIMAP workunits. Before downloading the SIMAP workunits about 5 weeks ago, the SoB WU received occasional CPU time along with some CPDN tasks. Ever since I received the SIMAP tasks, the SoB task has never seen a single CPU cycle. It finally started running yesterday, presumably because it became the task with the shortest deadline. The deadline is 20 SEP, with 22.8% complete and 902 hours remaining!

I have not been tinkering with projects or WUs during this time. All projects are set to "no new work", except for SIMAP.
The relative priority for SIMAP is 100 and Primegrid is 10000.
The computer runs 24/7 and very rarely is BOINC paused.
2x quad-core Xeon E5520 with HT (16 WUs working at a time)

So, should I kill this WU, or keep crunching?

It has already been reissued to someone else, but if I continue it will certainly finish before they do. Will I get any credit for it?

I'm getting really sick of Primegrid tsks timing out because BOINC doesn't seem to place any priority on giving them CPU time.

Keep crunching.

Yes. Even if you return it after the other computer, you'll still get credit as long as the result is correct and the workunit hasn't been purged from the database. Furthermore, with SoB, there's a good chance that the other computer won't return the result at all, for various reasons, so your calculation is still needed.

It's pretty bad at that. I generally tend to run only one project (or subproject) at a time on each computer.
