Remote System Access

Accessing the cluster

• To access MANIT HPC you need to “ssh” the login server
• The Master node is primary gateway to the rest of the cluster, which has a job scheduler (called OpenPBS). You may submit jobs to the queue and they will run when the required resources are available.
• Please do not run programs directly on master node. Master node is use to submit jobs, transfer data and to compile source code. (If your compilation takes more than a few minutes, you should submit the compilation job into the queue to be run on the cluster.)

Remote access from Windows Desktop

1. PuTTY is the most popular open source “ssh” client application for Windows, you can download it from (http://www.putty.org/). Once installed, find the PuTTY application shortcut in your Start Menu, desktop. On clicking the PuTTY icon The PuTTY Configuration dialog should appear. Locate the “Host Name or IP Address” input Field in the PuTTY Configuration screen. Enter the user name along with IP address or Hostname with which you wish to connect.

      (e.g. [username/scholarID]@hpc.manit.ac.in)

   Enter your password when prompted, and press Enter.

2. Users can also access the HPC cluster via MobaXterm. This is an application that provides X-Server capability for the Windows operating system. This allows applications running in the Unix/Linux environment to display graphical user interfaces on the Windows desktop.

      (e.g. ssh  -X  [username/scholarID]@hpc.manit.ac.in)

   Enter your password when prompted, and press Enter.

Remote access from Mac / Linux Desktop

Both Mac and Linux systems provide a built-in SSH client, so there is no need to install any additional package. Open the terminal, connect to an SSH server by typing the following command:

    ssh [username]@[hostname]

For example, to connect to the HPC Master Node, with the username:

    user1: ssh user1@hpc.manit.ac.in

You will be prompted for a password, and then will be connected to the server.
