How often do you have boinc switch between projects?

[Bradtech519]

I've left mine at the default 60 minutes. Wasn't sure if that was efficient or not. I can almost get 16 workunits done for asteroids before it switches back to other projects.

Mine was default at 120m

 

[Fardringle]

Mine is set at the same default as T Yamamoto (120 minutes).

mine is set to 1450 minutes (24 hrs and 10 min), for a specific reason of course. on my office machine, i run 2 CPU projects - LHC@Home & Test4Theory@Home. b/c the new T4T@H tasks are limited to running on a single core (for now), that means 5 LHC@Home tasks are running concurrently at any given time. if i leave task switching set to 60 minutes, this host will crunch 1 T4T and 5 LHC tasks for 60 minutes, and then switch to 6 LHC tasks. sometimes the T4T task resumes after 60 minutes, but more often than not, it remains in the queue "waiting to run" while 6 LHC tasks continue to crunch away. having changed my task switching to 1450 minutes, my T4T task now has the full 24 hours it needs to complete, plus an extra 10 minutes for any calculations that might (and occasionally do) run over the 24-hour mark...usually it only runs a few seconds over, and more rarely a few minutes over, so i thought an extra 10 minutes might be a nice safety margin. having the task switching set this way also allows a new T4T task to be downloaded and started almost immediately after completing, uploading, and reporting the previous task. with task switching set to 60 minutes, although a new T4T task might get downloaded just afrer the previous task is reported, there's a good chance it won't start running right away, and that it'll sit in the queue behind a decent chunk of LHC tasks.

I also have 60 minutes. I don't think that I have ever changed that one. I would classify that as, "since it ain't broke, i haven't fixed it."

I'm still running boinc 6.12.xx

Does anyone know what happens if you change it to blank or zero?

 

[Sunny129]

i can't find an answer for that, not even in BOINC's own documentation.

Does anyone know what happens if you change it to blank or zero?

This depends on how you're setting it, but you will either be denied setting it to zero/blank, or it will automatically switch to being 60 minutes. If you manually set it to zero in global_prefs_override.xml it will be interpreted as 60 minutes.

It's rare that I crunch more than one CPU project on the same computer.

I like to hit a project hard with 3 or all 4 of my computers until I reach a milestone goal.
