We use it, and it’s great … except … It’s so darn ancient it can be tough to compile on modern platforms. I’m currently using it on RHEL4, and beginning to experiment with RHEL5, but so far the RHEL5 has not been successful. I don’t know if it’s going to be a simple fix yet, hopefully it is.
Depending on your environment, “module” can be really powerful, but we just use it to add/remove paths from PATH, MANPATH, etc. Since we’re using so little of its capabilities, I would seriously consider just scripting up some intelligent scripts to add/remove these environment settings. It would be simpler and more comfortable to maintain, but of course I’m entrenched (and so are the users) … for us, modules is here to stay. From: [email protected] [mailto:[email protected]] On Behalf Of John Reddy Sent: Thursday, February 11, 2010 5:13 PM To: LOPSA Technical Discussions Subject: [lopsa-tech] Loadable shell "modules" One of my users, bless his heart, has requested I install a tool called "modules". That's all he's been able to describe it to me as in terms of name. Apparently, it's a program that allows users to load or unload grouped sets of environment variables. See, we've got a clustered processing environment with 120 dual-quad nodes running Scientific Linux 4.x and 5.x (SL is a RHEL derivative like Centos) with job control via Torque & Moab. We've got three different compilers with multiple versions each, a variety of implementations of MPI, etc. So a tool such as this would be useful for my users. Now the MPI selection is easily handled with mpi-selector. And I could probably (easily) enlist that tool for environment selection. However, I'd like to see if I can find someone using the tool my user requested. TIA for any thoughts on the matter. -John
