Running slurm job in HPC

[avgils]

@nikosT

I cannot submit a job with sbatch. I followed these steps:

• Create simple task test.sh:

  !/bin/bash

  SBATCH --job-name=hisea # Job name

echo "hisea"

• submit with sbatch --nodes 1 --ntasks-per-node 1 test.sh

I tried some different options for the slurm command but I get an error: sbatch: error: Batch job submission failed: Invalid account or account/partition combination specified

How can I solve this?

Another question: Do we have a project drive available to share jobs and data between team members?

Extremely minimal job script. Have a look in https://doc.aris.grnet.gr/scripttemplate/ how a job script should be. In your case you should use --account=hisea and --partition=el7taskp. The syntax of sbatch should be --KEY=VALUE for example --ntasks=1.

No there is no project drive. What's the reason for separate accounts when you share jobs and data ? Probably the best solution is to allow multiple public keys in one username ?.

Thanks, I looked at this documentation: https://doc.aris.grnet.gr/run/job_submission/, is it maybe an idea to refer to the script template here?

I submited a job succesfully :)

In other environments I'm used to own accounts that can work on multiple projects. You can login with one account but work on multiple projects with that account. A shared drive is mostly available to store projectdata and is available for every projectmemeber.

I could share my key with Lornic since I made a key specific for this environment. Can we login both at the same time? Should we store our data in the homefolder?

Regarding the key, you could simply add Lornic public key to the authorized_keys and both can connect to the same ARIS user. Obviously you can login both and multiple connections. Data location : It depends on the number and size of data. It the files are small, yes in home folder. If they are large, use the three in $WORKDIR : echo $WORKDIR to see the location.
