I didn't expect this in SETI!

Now granted it has a deadline of Sept. 9th, but still... SETI is taking a 4+ days ride through my RTX 2060 processor? Until now, every SETI task that has a "1 CPU + 1 NVIDIA GPU" label has been extremely short, 3-6 minutes. Anybody have an explanation? *George* ID: 2008688 ·

I just restarted BOINC and also ran Task Manager in Windows to find out and verify that while BOINC is running (all threads with 100% utilization) and it is still at 4.00 Ghz CPU speed, boosted from a 3.47 Ghz normal. As usual, the app tasks running have changed while doing this, so I can't say whether or not it is fixed. Only time will tell. *George* ID: 2008692 ·

Reducing the number of CPU tasks being done by 1 and those CPU task run/CPUtimes should close up to within a few minutes and not the 20-30mins that you're getting now (100% CPU loading should be avoided).

Once again, pardon my ignorance, but just how do I "reduce the number of CPU tasks by 1"? And how, or more correctly why should I avoid 100% CPU loading? *George* ID: 2008697 ·

BOINC will by default use 100% of CPU resources, but that will leave you nothing in reserve for your O.S., antivirus and other programs that you may use and this is what causes an overcommitted CPU.
