Hi Micheal, This doesn't seem to work as advertised. The options never get
sent to the job. Testing with SLURM_JOB_NAME exhibits the same issues. Do you
or anyone else have any other ideas? Kelly On 04/24/14, Michael

interesting: The task prolog is executed with the same environment as the
user tasks to be initiated. The standard output of that program is read
and processed as follows: /export name=value/ sets an environment variable
for the user task /unset name/ clears an environment variable from the
user task /print .../ writes to the task's standard output.
http://slurm.schedmd.com/prolog_epilog.htmlSo what you want is:#!/bin/bashecho
"export SLURM_DISTRIBUTION=block:block"Though I've never modified a Slurm
environment variable, so there may be other things at work.MOn Thu, Apr 24,

looking at SLURM_DISTRIBUTION, SLURM_CPU_BIND and the like. Looking those for
both sbatch and srun. A simple script was created for the Prolog and
taskProlog options: #!/bin/bash export SLURM_DISTRIBUTION=block:block When we
set it prior to sbatch or srun like so export SLURM_DISTRIBUTION=block:block
srun -N 2 sleep 5 it works just fine. ThanksKelly On 04/24/14, Michael

environment variables for processes running in a Slurm job? Not setting or

prologs should work for this purpose- they're working for us OK[1]. There is
also the use_env SPANK plugin[2] which we've used with some success as well...
I think it does much of what you'd like to accomplish.IIRC, these things work
differently between sbatch and srun, which are you using? srun has the
--task-prolog=<path> option. What happens when you use that? sbatch has an
option "--export-file" which might have some utility for your purpose, but I've
never used itMaybe post your task prolog?BestM[1]

to set default SLURM environment variables for all users. I'm newish to SLURM
and tried using Prolog and Task Prolog with no avail. The goal is to not write
a plugin. Is the best way to set them outside of SLURM in the user's
environment and have them overwrite via the command line if desired? Thank you
in advance for any and all suggestions! Kelly -- Hey! Somebody punched the
