I've run ach wu's on this pc before, though it only has 1G. The current wu has a status of waiting for memory. So I suspended all other projects and restarted BOINC, so that nothing else from boinc was in memory. However it this wu immediately goes into a waiting-for-memory status. Since it won't load I can't see how much memory it needs. Do I have any choice other than aborting it? (no, I can't stuff more memory in the pc) Or is there a way to find out how much memory it wants?

Yes, you can check the memory needs manually by searching through the client_state.xml file.
I forget what the normal ACH memory footprint / minimum requirement is. Anyone? |

Dont abort please please and tell us of all your settings.
----------------------------------------Since you just restarted, go to the BOINC message window and copy first 20 messages or so until after it goes into the 'waiting for memory' state. Have had it with the Help Defeat Cancer jobs in past when having only 1gb.... changing settings resolved that (and adding 512mb ram), but first like to see yours before jumping in. ttyl

Thanks for the quick responses. (I just realized I've run ach successfully on my laptop which has only 512 GB) Anyway I have since rebooted, and increased my paging file size but that's not in effect yet. Also bumped the max usage settings in the profile; could be bumped more. I'm trying to get a HCC wu finished and out of the way before doing more surgery. Meanwhile relevant messages from startup are:

If so I should have had enough; it's a headless pc I don't use interactively so it should have been "idle" until I started trying to diagnose things. But since I have experts to ask I'll await your advice before tweaking more stuff. Thanks! |

Yes, you may want to increase your
----------------------------------------1/20/2008 12:21:26||Preferences limit memory usage when active to 511.50MB setting. Surely it will resume when your machine is not used given that 1/20/2008 12:21:26||Preferences limit memory usage when idle to 920.70MB allocates considerable more ram. Missing though a few more lines where it prints e.g. the swap file permitted use and allocation. Set that to 2gb and e.g. 75% and you should be doing great from thereon. The 691/553 is not enough if reading the client_state correctly.

I agree with Sekerob.
For a headless machine, set the "active" setting the same as "idle". BOINC determines activity based on mouse and keyboard activity, not CPU activity. This means logging in is suspending the task, as you've figured out. |
