Getting Access

Access to the cluster is subject to formal approval by selected members of the participating research groups. See the HPC Service Webpage for more information on access options.

Introductory Linux Training and Resources

If you're not familiar with basic Linux commands and usage, or if you need a refresher on these topics, please refer to the following resources from our workshop series:

For a list of upcoming research computing workshops and events, please see:

Logging In

You will need to use SSH (Secure Shell) in order to access the cluster.  Windows users can use PuTTY or Cygwin. MacOS users can use the built-in Terminal application.

Users log in to the cluster's submit node, located at or use the shorter form  If logging in from a command line, type:

$ ssh <UNI>


$ ssh <UNI>

where <UNI> is your Columbia UNI. Please make sure not to include the angle brackets ('<' and' >') in your command; they only represent UNI as a variable entity.

Once prompted,  you need to provide your usual Columbia password.

Submit Account

You must specify your account whenever you submit a job to the cluster. You can use the following table to identify the account name to use.

Your First Cluster Job

Submit Script

This script will print "Hello World", sleep for 10 seconds, and then print the time and date. The output will be written to a file in your current directory.

In order for this example to work you need to replace ACCOUNT with your group account name. If you don't know your account name the table in the previous section might help.

# Simple "Hello World" submit script for Slurm.
# Replace ACCOUNT with your account name before submitting.
#SBATCH --account=ACCOUNT        # Replace ACCOUNT with your group account name 
#SBATCH --job-name=HelloWorld    # The job name
#SBATCH -N 1                     # The number of nodes to request
#SBATCH -c 1                     # The number of cpu cores to use (up to 32 cores per server)
#SBATCH --time=0-0:30            # The time the job will take to run in D-HH:MM
#SBATCH --mem-per-cpu=5G         # The memory the job will use per cpu core

echo "Hello World"
sleep 10

# End of script

Job Submission

If this script is saved as you can submit it to the cluster with:

$ sbatch

This job will create one output file name slurm-####.out, where the #'s will be replaced by the job ID assigned by Slurm. If all goes well the file will contain the words "Hello World" and the current date and time.

See the Slurm Quick Start Guide for a more in-depth introduction on using the Slurm scheduler.
