Message 68695 - Posted: 24 Nov 2010, 4:00:21 UTC

I am a hands-off RH user, so I don't spend a lot of time configuring my preferences. BOINC is telling me now that it can't run any work because my preferences have memory usage limited to 204.8 MB when active, 1024 MB when idle and limiting disk usage to 0.00 GB.

I have re-configured in a number of ways, and here is where it is now. I can't see where the problem is. Please help.


Disk and memory usage
Use at most- 10 GB disk space
Leave at least-
(Values smaller than 0.001 are ignored) 0.01 GB disk space free
Use at most- 100% of total disk space
Write to disk at most every- 60 seconds
Use at most- 25% of page file (swap space)
Use at most-
Enforced by version 5.8+ 50% of memory when computer is in use
Use at most-
Enforced by version 5.8+ 100% of memory when computer is not in use

Those preference settings seem fine, but are you setting them at the website or at the preferences tabs on your own computer's BOINC Manager? You might have some funny settings there overriding the website preferences. If you haven't done it, open up the BOINC manager preferences and go to the "Disk and memory usage" tab. Check your settings there.

The requirements for Rosetta show you need at least 250 MB per task. Lately I've seen some tasks that require 400+ MB. Am I correct in thinking your computer has 1 GB? It's a dual core right? That could add up to more than 800 MB for Rosetta alone. You could beef up the memory use when not idle to say 80%. But even then you could run into memory problems, because the OS and other programs also need memory. If you want to continue to crunch for Rosetta, a better option could be to crunch at most on 50% of your processors. Leaving more headroom for your normal activities on that computer.

When resources are limited, you will get less crunching done. In the case of your original settings, you probably don't get much R@h done when your machine is active. Looks like you've now increased the memory used while active from 20% to 50%. That should make a significant improvement in the ability to crunch R@h when the machine is also active doing other things. If your use of the machine is not noticeably impaired by that, then you have struck the required compromise.

Message 68727 - Posted: 30 Nov 2010, 11:11:46 UTC - in response to Message 68699.  

Thanks for the info. It was the settings in the BOINC Manager. I was telling it to leave 50 GB free disk space, which is where I originally set it up when I joined (and my machine was fairly new) Now I have about 40 GB of memory left so it was doing what I asked it to do. We are crunching again! Thank You!
