1) Message boards : Number crunching : Too much Virtual memory is being used (Message 42445) Posted 22 Jun 2007 by GreenBandit Post: Unfortunately for me, the PC in question (368896) is picking up on the correct location, but it was a good check to make. I think this is now closed as far as Rosetta is concerned as I will be posting the "not removed from memory while suspended" and "exceeding VM limits" issues on BOINC boards. Mod.Sense & Anders n, thanks for the help :-)
2) Message boards : Number crunching : Let's stand up to the -1 moron (Message 42442) Posted 22 Jun 2007 by GreenBandit Post: its gotta be automated - i can't believe anyone could be sad enough to do that manually! I think it actually could be a person doing it manually - one of my recent threads had my question (which I admit was worded badly) left with a rating of zero, but the answer posted by a moderator had been rated -1 (now corrected).
3) Message boards : Number crunching : Too much Virtual memory is being used (Message 42437) Posted 22 Jun 2007 by GreenBandit Post: Is is possible that the trigger for multiple Rosetta application all waiting for memory and all using >150MB of VM was triggered by me setting the allowed amout of real memory too low? Yes I would say that it is very possibel. Have you thought about increasing your VM? Anders n I did think about this, but I am after both a solution to the specific problem on this machine AND a general solution to ensuring that BOINC does not resource-hog on my other machines. So while increasing the size of the VM would probably remove the Windows "....low on virtual memory..." error, it would not get round the problem of why 450MB out of a 1150MB swap file was being used by Rosetta when the limit that I put on VM usage was 10%. If it really was "setting the allowed amout of real memory too low" that caused the hogging of VM by 3 instances of Rosetta then I will probably not get any more critical errors, but it still does not explain why almost 204MB of VM is being used by Rosetta when a 5% limit of a 1150MB swap file is only 57.5MB.
4) Message boards : Number crunching : Too much Virtual memory is being used (Message 42432) Posted 22 Jun 2007 by GreenBandit Post: To answer the questions put to me:- Rosetta & Seti are running, Windows 2000 SP4 is used, CPU is a socket A Athlon 2400+ running at the std 2000MHz, HT not supported. I've unhidden the computers, so at least they can be seen now. Regarding the memory being used, Real memory present=768MB, VM present = 1150MB(fixed), Rosetta 5.68 memory usage (as reported by Task Manager) = 121,572k of real memory (honest - it really is "over 10% of real memory on a 768MB machine") & 203,988MB of VM. The limits that I have are 50% of memory while in use (PC is normally in use during the day), and 5% of swap file. So it seems that the current swap file usage limit of 57.5MB is being very much exceeded. I can put up with a small amount of slow task switching (I consider a small amount as up to 5 seconds), but some times a task switch has taken 20 seconds when there are 3 or so Rosetta tasks all in memory all using over 150MB of VM. On several occasions, even though I am only using M/S outlook and Word, the PC has given a "low resource error". I know I could get rid of this by allowing a variable size swap file, but I am trying to keep HDD fragmentation to a minimum. This is what I don't understand, even though they have been set to be removed from memory when suspended, how is it that I had 3 tasks in memory all using more than the VM limit that I have set. Today things are running OK (in terms of task switch times), but I still seem to have more VM resources being used than the limits I set and if I can't control the resources being used I am concerned that I may get other problems when I try to remotely access the PC from home. Is is possible that the trigger for multiple Rosetta application all waiting for memory and all using >150MB of VM was triggered by me setting the allowed amout of real memory too low?
5) Message boards : Number crunching : Too much Virtual memory is being used (Message 42401) Posted 21 Jun 2007 by GreenBandit Post: One of my lo-spec machines that I run Rosetta on (while working) has recently (sometime in the last few weeks) started being extremely slow when task switching due to large amounts of VM being used by Rosetta applications. Athlon 2400+ with 768mB RAM, fixed swap file of 1150MB. BOINC manager = 5.10.7 (same symptoms did happen with 5.8.16) When the slow task switching occurs there are always a number of Rosetta applications that BOINC manager says are "Waiting for memory". Task manager is currently reporting that there are a total of 3 Rosetta application left in memory even though I have set:- applications to be removed from memory when suspended, max page file to be used = 5%. Each of the 3 Rosetta applications is using over 15% (i.e. over 150MB) of the swap file!!?? I have just increased the amount of memory to be used (idle & in use) from 10% to 50% but I still have one Rosetta application using 170MB of VM. Can anyone help ?
