That's excellent; I've been using the 'auto_tmpdir' plugin for this;
having that functionality within SLURM will be good.
Have a question though - we have a need to also create a per-job
/scratch/ (on a shared fast file system) in much the same way.
I don't see a way that the currentl tmpfs plugin can be used to do that,
as it would seem that it's hard-coded to mount things into /tmp/ (i.e.
where to mount a file system can not be changed). Or am I misreading this?

One errant backspace snuck into that announcement: the
job_container.conf man page (with an 'r') serves as the initial
documentation for this new job_container/tmpfs plugin. The link to the

We are pleased to announce the availability of Slurm version 20.11.5.
This includes a number of moderate severity bug fixes, alongside a new
job_container/tmpfs plugin developed by NERSC that can be used to
create per-job filesystem namespaces.
Initial documentation for this plugin is available at:
https://slurm.schedmd.com/job_container.conf.html
Slurm can be downloaded from https://www.schedmd.com/downloads.php .
