You shouldn't need to do anything like that, as with each change of project applications are swapped out of memory and new ones start. At least at the default setting of "Leave applications in memory" set to No.

Even applications within the same project, when tasks end and new ones start, they do so with their own science application, leaving memory and starting anew.


I did that and added 16GB of memory, everything works fine now and with more comfort when working on the machine.

Thanks again !

Apparently this seems to solve the memory usage problem, after several task and project changes.

Thanks a lot !

Ok, I modified this parameter in the preferences of each project I restart Boinc to see. I am at 80% memory usage for the Boinc projects, I ordered 16GB of additional memory.

Thanks again for your help.

Because that exits the tasks out of memory and restarts them, possibly from the beginning.


Apparently they start again where they were stopped...

The problem is that it must be done automatically at each change of project, and that I do not know how to do...

What is your setup for Atlas tasks? How many CPU cores are you using per task? This can be setup on LHC web site or by an app_config.xml. Are you using VirtualBox or are you running Atlas tasks as native linux tasks? On LHC website project preferences you can also limit how many tasks you have on your computer at one time. On Boinc preferences (locally with Boinc manager or on project website) you can limit how many CPU cores you allow Boinc to use at any time.


The problem occurs whatever the project, I have the same thing with Einstein@home the only way to correct the problem is to run "boinc-client restart" when it happens ...

In fact I have the problem with each change of project...

For the moment I will have to stop using Boinc on my machine

I have the same problem with LHC@home ATLAS Simulation and VBoxHeadLess on startup the memory usage goes up to 95% I have to run "boinc-client restart" to get the memory usage back to normal.

I don't understand where the problem comes from and how to solve it.

The last column shows the actual process taking up the memory, which in this case is an Einstein application (times 4). If these are the ones taking up all the memory, then you'll have to report this to the Einstein project https://einsteinathome.org/community/forum


They use on average 13% of memory each for the moment it is stable after restarting boinc-client, I will report it to the Einstein project.

Thanks again !

Thank you for your answer, but what is curious is that I had not noticed this problem before for a year, on the other hand if I run "boinc-client restart" the memory use decreases but goes up gradually ...

For some time Boinc after a day or two has been using all the memory (16GB) and a good part of the swap and my machine therefore becomes very slow, I participate in Einstein@home and LHC@home, how to solve the problem?

I run version 6.10.58 for x86_64-pc-linux-gnu


That is a very old version of BOINC. Current is 7.16.11

I wonder if it is running such an out of date version that is the problem. What version are you running on your other machine?


On the other machine I run the 7.16.6 x86_64-pc-linux-gnu on Ubuntu 20.04 desktop.

The machine is an old server and I can't upgrade it's a vserver kernel:

Linux soleil-host 2.6.32-5-vserver-amd64 #1 SMP Fri May 10 10:52:10 UTC 2013 x86_64 GNU/Linux


I don't know if I can run the last version or a more recent version on it ?
