Re: Dynamically change number of jobslots

[Joe Sapp]

You could use an sshloginfile with just the localhost and the number of processes. Something like this in the file:

4/:

Then change the number in the file and you'll change the number of jobs next time a job is finished.

Is it possible to signal a running parallel process to change the value of -P N ?

Currently if I need to change that I use pkill -STOP parallel to stop any new jobs from starting and then kill/restart parallel with a new value, but it would nice to be able to do that without having to drain the queue (or losing stdout/stderr during draining).

P.S. This is fantastic tool, and I wish I had upgraded from xargs years ago!

Thanks.
