1) Message boards : Number crunching : How to limit the number of parallel WUs and sized HW to run all of them (Message 692)

Post:
My crunching server (4 cores, 8GB RAM) doesn’t have enough resource to run 4 parallel VMs/WUs nanohub.

Just to the nanohub project, how can I limit the number of cores or the number of parallel WUs?

The WUs/VMs deployed at the beginning of April 2021 need:
*) 3GB RAM
*) from 1GB to 3 GB in the boinc/slots directory
*) the process to build the VM from scratch requires a disk performance bang

When boinc client runs all the WUs/VMs the server CPU core can, the server stops responding!!
So, I’m looking for the best way to throttle nanohub WUs/VMs.

In BOINC settings, are you allowing enough memory to be used? I set it to 95%.

The memory usage was 90%, so I'm going to increase it.

I usually limit it to a maximum of 8 work units at a time

How can I do it?
