[Beowulf] software for activating one of many programs but not the others?

Hi

I think modules can help here - http://modules.sourceforge.net/

This is usually packaged as "environment-modules" under most distros.

Typically you would set up small config files for each package/version. In the file you normally "prepend" the package directory to PATH, LD_LIBRARY_PATH, etc


Cheers,
Fred
