Its not clear to me what you are asking.
For example, if there are 4 executors on one slave and 4 on the other one,
the parallel branches might run on different slaves or they might run on
the same slave but different executors. I set the number of executors equal
to the number of cpus (or number of reliably runnable threads) on a slave
so the way this works at assigning executors allow the branches to truly
run in parallel though they might be waiting on each other for I/O or other
shared resources on the slave.
If you really need the jobs to run on different slaves there are several
things you can do.
1) Set one executor per slave OR
2) Give the slaves different labels and use those labels in your
"node('label")" in the closures you build in your loop.
