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.

Create a file app_config.xml in the project directory with the contents for fi max 3 jobs:

<app_config>
  <project_max_concurrent>3</project_max_concurrent>
</app_config>
