This poor machine gets suspended about 14 times per minute. No wonder it progresses so slowly. It is a wonder it gets anywhere at all.

The %age CPU time in boincmgr is set to ~50%. The difference between the wall-clock time is ~1min and the last CPU time given is 27secs, about a half:

  22:59:51 STEP  819 H= 819:00 +CPU= 42.573
  23:00:47 STEP  820 H= 820:00 +CPU= 27.309

I'd guess it was a laptop or mini-PC. I set mine at 60% otherwise it gets too warm if I'm running multiple tasks on it.

I prefer to run fewer concurrent tasks if things start heating up rather than reduce the percentage of time cpu is running them.

That is what I do too. Right now I would be running12 concurrent boinc tasks on my 8/16 core machine because it is cool here in my non-air-conditioned room. In summer, when it is hot, I reduce it to 8 or even 7 if it gets really hot.

Actually, I am running only 11 tasks because I have not gotten any Rosetta tasks in a very long time, and only one CPDN task every few days lately. So I am grinding out a lot of MilkyWay and Universe tasks that do not really interest me.

There's always Asteroids or even MooWrapper or even Cosmology if you want to stick with 'space' projects. If you want to branch out a bit there are LOTS of other project that would love to see you help them too, even some that aren't in the Boinc Manager list of projects unless you've manually downloaded and updated it and even then some are still missing. ie Albert is the test project for Einstein, LHC has LHCdev, Rosetta has Ralph and PrimeGrid has Composite Grid as it's test project, There also basic projects like Gaia, Private GFN Server, SiDock, Yafu, TN-Grid and Wanless. Also Ithena has a 2nd project using comp instead of root at the beginning of it. Not ALL projects have both Windows and Linux tasks and the test projects are often out of work but you should be able to find something else that tickles your fancy in one or more of those.
