Depending on a Linux system's setup, it may have the central Linux NFS software share mounted from the Engineering file server, which is configured to use Lmod. Lmod is a very useful tool to allow you to load/unload application configuration settings into your environment on the fly so you can use the software with ease. Lmod is also used by the Ohio Supercomputer Center (OSC).
How do I know if my system has the central Linux NFS software share mounted?
A quick way to check if the system you are using has the central Linux software share mounted is by typing:
- df | grep 'naotvs1socc.coeit.osu.edu:/nfs_opt_local'
If you see a result, and its mount point on the local system is /opt/local (it'll be the last thing on the line), the system likely has the software share mounted and the info applies to the system. If you're still unsure, please open an ETS ticket (https://ets.osu.edu) and in the ticket's description, mention that it is a Linux and what the hostname of the system is, and one of the ETS Linux team members will assist as soon as they are available.
What are some common commands and where can I find more info?
Software that is available from the Engineering Linux software share can be listed by typing module avail. To add/remove software to your current environment, you use module load/unload <application name from “module avail” list>. Once you use module load <application> to load the application into your environment, you can run the software by typing commands normally associated with it (e.g. “matlab”).
Additional info on using the “module” command can be found at https://lmod.readthedocs.io/en/latest/010_user.html.
