Under account-info, general preferences you can switch between yes or no for leaving the application in memory while it is preemted.

This means, when another BOINC-application is active, rosetta should save its work and leave the memory. This does not work on my system, where I set the option to 'no'. All my other BOINC-applications work right.

In state preempted, the process rosetta_4.79_windows-intelx86.exe uses nearly 70 MByte real memory and another 145 MByte virtual memory without using CPU-Power.

Is it a bug?

Maybe but probably not.

The BOINC client will automatically leave apps in memory if they have not checkpointed yet. The rosetta app currently checkpoints infrequently, about 4 times per workunit. Because of this it is recommended that you increase your switch time to about 120 minutes and leave applications in memory. I personally have only increased my switch time, I run too many projects and restart my computers too often for leaving in memory to help much.

Hi,

I have a similar problem, but I am adding more detail:

I run only Rosetta@home.
I have set:
Leave applications in memory while suspended = NO on my web account with Rosetta. I have updated my clients. I use only the default preferences. I have not setup home, school or work preferences.

All of my preference changes worked except for my leaving application in memory to no. Rosetta eats up over 100MB of memory, and I cannot afford to leave it in memory when I am doing work.

C:Program FilesBOINCglobal_prefs.xml does NOT have an entry for leaving application in memory. Even though it updated all my other changes correctly.

Is this a bug with Boinc? Can I correct the global_prefs.xml by hand until this bug is fixed?

Thanks,

Ed J.

I have a similar bug. rosetta_5.51_windows_intelx86.exe steals 115 356 kB memory when computer is in use.

What an interesting statement. It would seem that Rosetta does not obey the Leave applications in memory while preempted? yes/no. Other BOINC projects do, I respect the different requirements for the projects but should'nt the project state up front that it does not obey this setting and you will loose memory to it.

pandem, please start a new thread to discuss the topic. A lot has changed since 2005 when this thread started. Rosetta should be freeing up memory when each task completes. I'm just seeing reports in the past week that there are cases where it does not.

Are you seeing issues similar to those described here?
