[slurm-users] prolog not passing env var to job

[Brian Andrus]

It seems to me, if you are using srun directly to get an interactive 
shell, you can just run the script once you get your shell.


You can set the variables and then run srun. It automatically exports 
the environment.

If you want to change a particular one (or more), use something like 
--export=ALL,MYVAR=othervalue

do 'man srun' and look at the --export option
