*: Packages labelled as "available" on an HPC cluster means that it can be used on the compute nodes of that cluster. Even software not listed as available on an HPC cluster is generally available on the login nodes of the cluster (assuming it is available for the appropriate OS version; e.g. RedHat Linux 6 for the two Deepthought clusters). This is due to the fact that the compute nodes do not use AFS and so have copies of the AFS software tree, and so we only install packages as requested. Contact us if you need a version listed as not available on one of the clusters.

In general, you need to prepare your Unix environment to be able to use this software. To do this, either:

  • tap TAPFOO
  • module load MODFOO

where TAPFOO and MODFOO are one of the tags in the tap and module columns above, respectively. The tap command will print a short usage text (use -q to supress this, this is needed in startup dot files); you can get a similar text with module help MODFOO. For more information on the tap and module commands.

For packages which are libraries which other codes get built against, see the section on compiling codes for more help.

Tap/module commands listed with a version of current will set up for what we considered the most current stable and tested version of the package installed on the system. The exact version is subject to change with little if any notice, and might be platform dependent. Versions labelled new would represent a newer version of the package which is still being tested by users; if stability is not a primary concern you are encouraged to use it. Those with versions listed as old set up for an older version of the package; you should only use this if the newer versions are causing issues. Old versions may be dropped after a while. Again, the exact versions are subject to change with little if any notice.

In general, you can abbreviate the module tags. If no version is given, the default current version is used. For packages with compiler/MPI/etc dependencies, if a compiler module or MPI library was previously loaded, it will try to load the correct build of the package for those packages. If you specify the compiler/MPI dependency, it will attempt to load the compiler/MPI library for you if needed.

Licensing, etc.

Although the authors of GULP have made it free for academic use, they have put some restrictions on it.

  1. It may NOT be distributed without the express permission of the author.
  2. Any commerical use (research or otherwise, including contract research) requires a license from Accelrys, Inc.
  3. Program is supplied on an "as is" basis.

To ensure the above conditions are met, the system wide builds of Gulp on the Deepthought clusters are restricted. To get access to these builds, please

  1. Register with the authors of GULP
  2. Contact UMD Division of IT staff to inform them that you have registered with authors and would like access to the software. Please include some "proof" of registration (i.e. a copy of the email from the GULP registration form with instructions on how to download, etc.).
  3. After receipt of such, IT staff will grant you access to the system builds of GULP and notify you.
