TRACE contains two broad categories of nodes: compute nodes, which handle the production research computing, and login nodes, which are used for managing files, submitting batch jobs and launching interactive sessions. Login nodes are not suited for production computing.
When you connect to TRACE, you are connecting to a TRACE login node. You can connect to TRACE via a web browser or through a command line interface.
See the Running Jobs section of this User Guide for information on production computing on TRACE.
Connect in a web browser(*Not Available yet*)
You can access TRACE through a web browser by using the OnDemand software. You will still need to understand TRACE's partition structure and the options which specify job limits, like time and memory use, but OnDemand provides a more modern, graphical interface to TRACE.
See the OnDemand section for more information.
Connect to a command line interface
You can connect to a traditional command line interface by logging in via:
- ssh, using your Andrew userID and password
SSH
You can use an ssh client from your local machine to connect to TRACE using Andrew userID and password.
SSH is a program that enables secure logins over an unsecure network. It encrypts the data passing both ways so that if it is intercepted it cannot be read.
SSH is client-server software, which means that both the user's local computer and the remote computer must have it installed. SSH server software is installed on all the TRACE machines. You must install SSH client software on your local machine.
Free ssh clients for Macs, Windows machines and many versions of Unix are available. Popular ssh clients (GUI) include PuTTY for Windows and Cyberduck for Macs. A command line version of ssh is installed on Macs by default; if you prefer that, you can use it in the Terminal application. You can also check with your university to see if there is an ssh client that they recommend..
Use ssh to connect to TRACE using Andrew userID and password:
- Using your ssh client, connect to hostname trace.cmu.edu
- Enter your Andrew userID and password when prompted.
