salloc doesn't do that.
We use a 2 line script called "sinteractive" to do this, it's really simple.

Hi Chris,
Thank you for your comments. I will look at Easybuild. There are quite a few
options to automate the creation of software modules.
I will be doing lots of reading this week-end.
By the way, i signed up to the Beowulf mailing list.
Thank you,

Hi John,
Regarding NFS shares and Python, and plenty of other packages too,
pay attention to where the NFS server is located on your network.
The NFS server should be part of your cluster, or at least have a network
interface on your cluster fabric.

Hi All,
I'm trying out using GrpTRESRunMins to prevent users from
opportunistically flooding an empty partition with long jobs. We have a
partition set up for each CPU type, and give each association
(account/user/partition) a separate limit based on that account's share of
the partition.

Thank you all for your answers, I will research some more along these lines!
Any other opinion is welcome

A feature that many slurm users might like is sbatch --time-min. Using
both --time-min and --time a user can specify the range of acceptable wall
times limits. This can make it much easier to keep jobs running right up
to the maintenance reservation. e.g.:
sbatch --time-min=30:00 --time=48:00:
In the “other ramifications” category, if you aren’t already planning to, you
might consider making this change during a maintenance period when all jobs are
drained. We tried to change from SelectType=select/linear to
SelectType=select/cons_res on the fly once (via “scontrol reconfig”) and

In the past we used the LUA job submit plugin to block jobs that would
intersect maintenance reservations. I would look at that.

I’ll second that – we have a cluster with 4 generations of nodes. We assign a
processor type feature to each node and require the users to ask for at least
one of those features in their jobs via job_submit.lua – see the code below.
For a job that can run on any processor type, you can use thi

The problem is that reservations can be in there yet have no effect on
the submitted job if they would run before the reservation takes place.
One can pull the starting time simply using something like this
scontrol show res -o | awk '{print $2}'
with output

Hi
I have added a user to multiple partitions. That account name actually
corresponds to a set of limitations which I define for a user.

You can use node feature in defining the node types in slurm.conf.
Then when requesting for the job, use -C toy just use those
node type.
