System Access:

• Accessing the cluster:

  • The cluster can be accessed through Assam University, Silchar LAN IP address provided, which allows users to login.
  • The master node (Entry node) may be accessed through ssh.
  • The master node has a job scheduler (called SLURM) for managing jobs.
  • For submitting jobs, always use a job script and sbatch command. For example: sbatch job_name.sh. Refer to “job_scipts” directory available for job script.
  • Do not submit the jobs directly on the master node, as the system will automatically terminate such jobs. Sometimes, it may take more than a few minutes for the job to be run on the cluster, hence submit the job into the queue.

• Remote Access:

  • Using ssh command:

    • Open the terminal, connect using the ssh command. For example: ssh username@ip (i.e; Assam University, Silchar LAN IP address provided). Then, it will prompt for a password, enter the user’s password and hence the ssh connection will be established.

  • Using PuTTY application:

    • Firstly, download it from (https://www.putty.org/) and install it.
    • Once installed, launch the PuTTY application.
    • The PuTTY Configuration dialog will appear.
    • Locate the “Host Name (or IP Address)” input field.
    • Enter the username along with IP address. For example: username@ip (i.e; IP address provided).
    • Enter the password when prompted and hence the connection will be established.
