Hello all,
I am trying to find some documentation on how Jenkins handles multiple
builds on a specific node. Does it spawn separate processes? threads?
How does it manage parallel builds? And can I see these running on
the OS? I have checked on our Linux OS but cannot find specific
processes that seem to match the build. We have a Linux machine with
16 CPUs, and I would like to make sure that Jenkins is using these
CPUs when running 10 build jobs at the same time. How can I monitor
this better and understand it better?
AFAIK build operations are handled by JVM so you would see threads for
builds there. Not sure if every build is a single thread and if they are
reused in any way.
Of course build might run another operation (especially if running shell
commands), which might be visible in the OS itself.
Regards,
Nux.
