12 Tasks running: Yes. Only 7 CMS running. Other projects are running because they use less RAM. I've seen this happen on many occasions. And if it was overloading my system then that other projects would have frozen or slow down too. Which they have not and finished on time.
Plus, all I have at the time is only 7 CMS download at that time anyway.

BOINC is automatic when it comes to RAM. BOINC will not go over projects that use lots of RAM. Note: when I said I'm only using 7 out of the 12 cores I have because of the lack of RAM I have. So, no it's not because it's running out of RAM. It's just not running any more CMS because of the RAM I have.
I've been running BOINC for years and seen other projects that are set to use all cores and lots of RAM but never used all cores because of the RAM limit and use other projects that used less RAM to use the rest of my cores. Note: That's including VBOX

I had no issues for years on this until now. CMS ran fine before.

Updating Windows, BOINC, Drivers, VBOX may have something to do with this new problem.

I just got a bunch of CMS Simulation and all of them get stuck on random % and all of them showing they got aborted long after from VirtualBox manager and still stuck in BOINC manger and VirtualBox. 7 of them from 18.407% to 0%.

Windows 10
BOINC v7.16.20
VirtualBox v6.1.30

Tru I can run 7 but BOINC starts to run 10 meaning BOINC is not seeing my max ram and what is running in the background before BOINC starts running any work units or checking the work units to see how much ram it needs before BOINC starts running it.

Note it should be set it and forget it. It did for years and now all of a sudden I come to find my computer froze and the memory is maxed out.

It also did it on TLP GARLI and ATLAS.

This is why your computer freezes. Unfortunately BOINC does not recognize the actual amount of ram used by one LHCb tasks and therefore starts more tasks than your ram settings would allow.

Sorry but changing anything to get it to run right is a work around and NOT a permanent solution. It ran fine for years until now. It should run without changing a thing when BOINC is not doing its job. BOINC should know how much RAM I have and how much is running in the background before it runs any work units but that doesn't seem to be the case.

BOINC should be set it and forget it. That's what BOINC does. But it seems to have a bug.

BOINC is not utilizing the ram I have and what is using right now before it runs the work units.

TLP and ATLAS both have this problem. BOINC ran 12 TLP GARLI each required 6.5Gigs totaling 120Gigs. Suspending all but one ran fine and nearly filled all my ram with the rest running work units on the rest of the cores.

Running LHCb Simulation v1.00. When running 12 of them on all 12 cores tend to fill my memory all the way up and freeze my computer if left alone. The last thing I see is a full memory when my computer froze.


Another think it doesn't seem to know what my internet speed is or do speed tests. It's running 12 LHC trying to stream which apparently 3Mps is not fast enough for all 12.

Solution have it do a speed test of my internet or ask me what my internet speed is to have it do so many at a time.

12 Gigs of memory.
