CTC: Introduction to Linux at the CTC

The CTC has a Linux Cluster, consisting of login and batch machines. If you would like to use Linux to run applications at the CTC and already have a CTC account, contact Pat Colasurdo and ask for access to Linux. If you do not have a CTC account, fill out an application for an Exploratory Account.

Machines

Development Machines: v2linuxdev.tc.cornell.edu, 4 machines, vii00001 through vii00004
Login Machines: linuxlogin1.tc.cornell.edu and linuxlogin2.tc.cornell.edu
Compute Machines: Affiliation is v2Linux, 108 v2 machines, vii0005 through vii0128
The batch scheduler for these machines is the Velocity Scheduler (vsched). This is the same as for the Windows machines, with minor usage differences.
Software on linux login machines

Login Procedure

Currently only set up for ssh access; any ssh client should work.
Example: From a Windows login node (e.g. ctclogina.tc.cornell.edu), issue H:\CTCToo~1\putty.exe , which brings up the following GUI:

Working Environment

After you login to linuxlogin1 or linuxlogin2, you will be running GNU bash.
Issue help to see a list of commands.
If you need to set change your password, type passwd.
Linux version: Red Hat Enterprise Linux AS release 4 (Nahant Update 4). You can find out about the version with the commands
