Getting 3 different host with this fullnode which should be using (mt). It only use 1 core and reserved the other cores.
They are all windows 64bit 8/10/36 core system with BOINC 7.6.22

Could we get more info about this setup?

Longest run before abort
wu: https://mindmodeling.org/workunit.php?wuid=22455038
task: https://mindmodeling.org/result.php?resultid=13465594
runtime 1,940.15 cputime 1,922.94

I like this will be tested but there is something wrong with those task so i would abort those.

Completed and validated https://mindmodeling.org//workunit.php?wuid=22457801
Run time(sec) 9,145.72 CPU time(sec) 9,041.53

So this was done with 1 core not 4 core as this host should be running with if this is is multi thread task.

Also noted on one of my hosts that the app reserved 2 CPUs but used only one.

I've noticed this task runs and takes up 24 CPUs but generally doesn't utilize more than 50% usage at best.

Thanks for letting us know,

This project as of Monday was no longer in the system. However, there may have been some lingering work units left.

These work units required a large amount of memory for some of the simulations that were running which required an additional cpu to sustain the requirements.

We will work with the modeler to make this run more efficiently.

Thank you for your support and happy crunching,

Brandon

Just got a whole batch this morning. I can confirm they seem to be only using 1 core for however many they reserve. In my case they were reserving 12 threads but was only using ~5% of total cpu(24 threads)

Native Java 1.7 Application - Full Node (Windows Only) v1.08 (mt)
I use this tread, both (mt) and got similar problem to it as v2.7 application.

I assume these task require high memory as like the other version. Got a few task today and notice that it used 22 mm_wrapper processes and cpu usage 0.1 avg 0.2 each.
How much does these task need? host is set to max memory usage when idle: 48422.71MB to 32 cores and should then be divided to 22 processes so it would be 2201MB each.

What i then not understand that it only use avg cpu usage at 0.2%. If this is correct how does the task get same cpu time as run time?

https://mindmodeling.org/result.php?resultid=17322222

It end up valid all of them and but could we get feedback if the task is set correctly to handle it in this low usage? Or does boinc manager flag those task as NCI.

Would like to test with full memory and cpu usage and see if we could handle it.
