Log In to a Cluster and Submit a Job

After creating a cluster, you need to log in before you can submit jobs. This guide explains how to quickly log in and submit a job.

Prerequisites

You have created an Fsched cluster and its status is Running. See Add Hosts and Create a Cluster.

Log In via Console WebSSH

1. Log in to the platform.
2. In the left sidebar, open Cluster Management.
3. On the clusters page, open the cluster you want to log in to.
4. In the node list, locate the node you want to access and click Remote Control -> SSH.
5. Wait until the SSH button becomes available, then click Connect. A new browser page/tab will open and you will be logged in.

Submit a Job from the Command Line

1. Create a job script named jobscript.sh.

   vim jobscript.sh
   
   Example content:
   #!/bin/sh
   #SBATCH --job-name=test_jobscript       # Job name
   #SBATCH --output=test_jobscript.log     # Stdout output file
   #SBATCH --nodes=1                       # Number of nodes
   #SBATCH --ntasks=1                      # Number of tasks
   #SBATCH --cpus-per-task=1               # vCPUs per task
   #SBATCH --time=00:10:00                 # Time limit (HH:MM:SS)
   #SBATCH --mem-per-cpu=1024              # Memory per vCPU (MB)
   hostname

2. Submit the job.

   sbatch jobscript.sh

3. View the output.

   cat test_jobscript.log
