Getting connected


Users connect to MCSR supercomputers via the Secure Shell (SSH) protocol. For Windows, we recommend using PuTTY (external link).

SSH Secure Shell does not support modern algorithms and will not work.

Mac OS X and Linux users should use the command line SSH client, named ssh, that is included with their operating system.


For security purposes, users cannot connect directly to the supercomputers. They must first connect to the hpcwoods gateway server, whose full hostname is You will need your MCSR username and password that you received when your accounts were created.

To connect the hpcwoods using a command-line SSH client, type:
ssh -l username

Note that new users will be required to reset their initial password when connecting for the first time.

Connecting to supercomputers

Once on hpcwoods, use the command line SSH client to connect to the supercomputer of your choice. For instance, to connect to catalpa, a user would run the command:
ssh catalpa

Transferring files

All MCSR systems share the same “home” filesystems, so any files uploaded to hpcwoods will be available on other systems. We recommend WinSCP (Windows only) or FileZilla (all operating systems) for transferring files. The command line scp utility can also be used.

When installing FileZilla, be careful not to install the “optional offers.” In FileZilla, use s as the host and leave the port empty.
