You have several options for accessing the CSDMS cluster. You can use:
SSH - Secure SHell
SSH encrypts transmissions between remote computers and secure computers. Use SSH for local and remote access to beach.colorado.edu.
To use SSH for remote computing on beach, you must have SSH software installed on your local computer. Your SSH client must be compatible with that installed on beach. If you do not have SSH installed on your local computer, see our SSH product page for names and sources of some available SSH software.
When you are familiar with SSH and have a client installed on your local computer, you will be able to SSH and/or scp to beach.
There are both free and commercial versions of ssh available for many platforms. For Unix/Linux-based systems (including Mac OS X) the most common ssh software is OpenSSH. OpenSSH is free and can be downloaded as either source or binaries. Microsoft Windows users also have several choices for ssh client support, including:
Using secure file transfer protocol (sftp)
sftp is an interactive file transfer program similar to FTP. sftp performs all operations over an encrypted SSH transport. It may also use many features of SSH, such as public key authentication and compression. sftp connects and logs into the specified host, then enters an interactive command mode.
From within sftp, all of the normal ftp commands are present. sftp does not support anonymous logins. A user account is required on the remote end.
For usage information, see the man page for sftp on the computer from which you are issuing the command.
Copying files using secure copy (scp)
The secure copy command (scp) works with secure shell (SSH).
For usage information, see the man page for scp on the computer from which you are issuing the command.
Copying files using rsync
rsync is an open source utility that provides fast incremental file transfer that also works with ssh.
The environment modules utility is available on beach for modifying your environment to find alternate compilers and software installed on beach.
To use modules you will need to add the following line to your startup rc file. If you are a C-like shell (csh, tcsh) user, add the following to your .cshrc file after all other path-setting commands,
If you are a Korn-like shell (sh, ksh, bash, etc.) user, add the following line to your .profile file,
After this setup is executed upon login, you can use the module command.
Please see our Environment Modules page for a more complete description.
Running jobs on beach
Note that jobs must be submitted to the cluster through Torque's qsub command. Jobs not submitted in this way, or jobs that are run on the head node will be unceremoniously killed.
Although we do not yet actively enforce disk quotas, we ask that users limit their disk usage in the following manner:
The backup schedule for /home is the following:
Depending on disk usage, and data compressibility our backup retention is between 3 and 4 months.
