FASTER is using the CentOS 7 Linux distribution on all nodes. The global file systems (accessible to all nodes) are organized by
Lustre Parallel File System. These are /home and /scratch. Both are hosted on the 5PB usable disk space
provided by DDN.
The batch system, although a very important part of the computing environment, is covered in a separate section of its own. More information on the batch system can be found on the Batch Processing page.
The default shell for FASTER (all nodes) is bash. Its environment is defined in the startup file, .bash_profile. It is read and executed when you login, and it resides in your home directory.
Each of the four login nodes can be accessed with ssh to faster.tamu.hprc.edu. To access a specific login node, you would need to use the specific name to ssh. To access FASTER, use the following command from your local machine:
[user1@localhost ~]$ ssh [NetID]@faster.hprc.tamu.edu
The use of the login nodes is for small-to-medium code development and processing. The most important
processing limits here are:
- CPU time - ONE HOUR per login session.
- Cores for Concurrent Use - EIGHT CORES per login session, on the same node or (cumulatively) across all login nodes.
ANYONE found violating these limits WILL have their processes killed WITHOUT WARNING. Repeated violation of these limits WILL result in account suspension.
More information about the hardware of each of the login nodes can be found on the Hardware Summary page.
Immediately upon logging in to FASTER, the following message about the status of your disk space use greets you (format may vary):
Your current disk quotas are: Disk Disk Usage Limit File Usage Limit /home 2.49G 10G 113 10000 /scratch 1.25G 1T 40 250000 Type 'showquota' to view these quotas again.
Note: It is important to pay attention to this information, as it shows how much space has been used in each directory. Hitting a quota limit can cause problems for the user and should be avoided.
More information on the specific file systems including limitations and information about expansions can be found on the File Systems page.
The Modules system organizes the multitude of packages we have installed on our clusters so that they can be easily maintained and used. Any software you would like to use on FASTER should use the Modules system.
NO modules are loaded by default.
The main command necessary for using software on FASTER is the load command. To load a module, use the following command:
[NetID@cluster ~]$ module load [packageName]
The specification of packageName in the load command is case sensitive and it should include a specific version. To find the full name of the module you want to load, use the following command:
[NetID@cluster ~]$ module spider [packageName]
To see a list of available modules, please use the mla wrapper script:
[NetID@cluster ~]$ mla
More information on the Modules system can be found on the Modules System page.
