Ticket 13102

Created attachment 22834 [details]
The slurm.conf file that is used for both versions

Hi,

Hope you had a wonderful Holiday!

I am resubmitting this as a new ticket on recommendation from Jason.

I am just doing a cut-and-past from the original bug 10889, I changed the title of the ticket to avoid confusing the discrepancy between salloc vs sbatch behavior in the previous ticket.

With the new version right now it is not possible to use Forge, so this is a little more disruptive for users.

--------- cut and paste from previous ticket ---------

Not sure if I should submit a new ticket but I am replying to this ticket because it was never quite resolved, and since Tony has retired we are short staffed and could not get you the logs/files you needed.

Now the issue is this.  If you remember, Forge worked fine with salloc but not with sbatch, this was the basic problem.

Now we have two versions of Slurm on our test system and Forge does not work at all the when run with the new version of Slurm!  Whether I try salloc and sbatch it does not work.

For the time being let us ignore the difference between salloc and sbatch.

Let us focus no salloc not working with the new version.

On our test system we are using the 21.08.2 version of Slurm:

jfe01.% ll /apps/slurm
lrwxrwxrwx 1 root root 9 Oct 18 10:40 /apps/slurm -> slurmtest/
jfe01.%

jfe01.% ll /apps/slurm*/default
lrwxrwxrwx 1 slurm slurm  7 Oct 18 12:22 /apps/slurm/default -> 21.08.2/
lrwxrwxrwx 1 slurm slurm 10 Sep 14 14:17 /apps/slurmprod/default -> 20.11.7.p2/
lrwxrwxrwx 1 slurm slurm  7 Oct 18 12:22 /apps/slurmtest/default -> 21.08.2/
jfe01.%

Our production system is still using 20.11.7.p2.

Using salloc, Forge works fine on our production system but does not work on our test system.

I am including the output below:

jfe01.% cd S2/forge-test
jfe01.% module load intel impi forge
jfe01.% salloc -A nesccmgmt -q admin -n 128
salloc: Granted job allocation 4966599

After setting the ALLINEA_USE_SSH_STARTUP to 1:

On our production system it works (I have edited program output for brevity):

I will upload the slurm.conf file and that file is same in both versions.

Wish you a Very Happy New Year!

Thank you!
