Hi,

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 Files\\BOINC\\global_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.

When the "leave applications in memory when suspended" is set to No, it doesn't show up in global_prefs.xml

That's the way to see it isn't used.
If it's set to Yes, there'd be a single entry like in the file.

I have this in my BBC-boinc advanced options

Leave applications in memory while suspended?
(suspended applications will consume swap space if 'yes') yes

As the BBC version of boinc is modified and restricted, members with the full cpdn boinc version must have this same option. The default answer is NO.

At the moment the server in Oxford is refusing to update preferences for the climate project (I'm not sure whether this applies to both versions of boinc) and this is likely to remain so until the server gets its next boinc upgrade. But preferences can still be changed manually by modifying the contents of the file.

I think the default setting is No, Maureen. Yet I could be mistaken. Maybe it is set that way only on later updates of the Boinc server software.

I just checked on CPDN (old server software) and Primegrid (new server software) in the Home venue... the "leave applications in memory when suspended" option is standard at No.

You're probably right; I can't remember what it said when I installed it. Maybe the default answer for BBC members was different because they knew that very few of us would have understood the choice!

The default answer to Leave in memory while preempted? certainly seems to be NO.

That's also showing that a project is using the old software. It's been "suspended" instead of "preempted" for a while now, as no one seemed to know what the heck preempted means. ;)

Yes, I've just discovered this for myself - I was wondering what the difference between the 2 questions was!

My version says 'suspended'. But I thought I also had the preempted question on another page, and of course I haven't.

The default answer is definitely NO. We have to tell everybody to change it to YES because the time between checkpoints is quite long.

Jorden, I've edited my first post in this thread to say NO instead of YES, so you should delete all our posts after that. Otherwise poor Ed Johnson will be totally confused.

Nah... I think I leave it standing for now. It's always a good thing to see the history of Boinc. And besides, if his global_prefs.xml doesn't show the line about leaving apps in memory, it isn't used anyway. So his settings are correct.

Ed, you did report this same thing on the Rosetta forums? If it doesn't want to yield, it may be their problem, not BOINC's.

Ed, there's been a very detailed discussion here about changing cpdn preferences manually. I think you need to look at Dagorath's post on 9 Nov and the posts after that.
