Dear Mahmood,
Docker is somewhat tricky, because it needs a daemon running and there
is no fine grained control over who is allowed to start and stop
containers. Also getting the container on the node can be unpleasant
(docker hub? private registry? build docker containers on the node
before running them?). I would recommend against it!
However, there are projects like Singularity or Charliecloud designed to
bring the "bring your own environment" idea to HPC.
We have Singularity installed, and some of our users use it. It seems to
work reasonably well, as I have heard no complaint except that the
available version is somewhat outdated...
Best,
Christoph

Hi
The question is not directly related to Slurm, but is actually related
to the people in this community.
For heterogeneous environments, where different operating systems,
application and library versions are needed for HPC users, I would like
to know it using docker/containers is better than yielding virtual machines?
Actually, it is lighter than VM, however, I haven't seen a docker image
for Matlab for example. If that is possible, can Slurm be used to
schedule containers?
If someone has any experience using docker in HPC clusters, please let
me know.
Regards,
Mahmood
