Access Using SSH

To connect to HPRC clusters, you must use SSH (Secure Shell). SSH is a client-server software that provides for secure (by encryption) logins and other communication between two hosts. SSH is freely available in the Internet for Linux/Unix and PC Windows (in the guise of MobaXterm).

To initiate SSH connection to target cluster's login node from campus, find the hostname and credential (userID/password) info from Table 1 below. For example, connecting to Ada cluster from a MacOS/Linux/Unix operating system, enter:

localhost$ ssh NetID@ada.tamu.edu

where the ada.tamu.edu address is a DNS round-robin alias for ada[1-8].tamu.edu. You will be prompted for your password in order to establish authentication. Once you login into one of the 8 login nodes, the shell's prompt will be NetID.ada[1-8].

Table 1 Hostname and credential info of HPRC clusters
Cluster Hostname Number of login nodes Credential (UserID / Password)
Ada ada.tamu.edu 8 (ada1 ~ ada8) NetID / NetID password
Eos eos.tamu.edu 5 (eos1 ~ eos5) Eos_ID / Eos password
Curie curie.tamu.edu 2 (curie1 ~ curie2) NetID / NetID password
Neumann neumann.tamu.edu 4 (neumann1 ~ neumann4) NetID / NetID password
Crick crick.tamu.edu 1 (crick1) NetID / NetID password

Access from Windows

Using MobaXterm (Recommended)

Using PuTTY

Access from MacOS

Remote Logins

Use the Terminal program, which is under Applications->Utilities.

On your Mac click the Finder Finder.png icon to start finder:

  1. Select Applications App-icon.jpg
  2. Double click the Utilities folder
  3. Double click the Terminal utility Term-icon.jpg
  4. A Terminal window will now appear similar to the one below.

Access from Linux/Unix

Off-campus Access

For connecting to cluster login nodes from outside the campus, you need to activate Virtual Private Network (VPN) first, then initiate SSH connection to the cluster login nodes. You can find VPN installation instruction from TAMU ServiceNow Knowledge Base page on VPN.
