Summary: Review Request: openmpi - a new MPI implementation https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=173719 ------- Additional Comments From ed@xxxxxxx 2006-02-15 20:45 EST ------- Hi Jason, is there any chance that you (and the other Red Hat packagers) would consider using environment-modules for side-by-side installs of different MPI implementations? Compared to the alternatives system, environment-modules is far superior. Alternatives does not (and probably never will) gracefully handle situations such as multiple implementations of the same API. For instance, what do you do with the LAM, MPICH, etc. man pages? If you use environment-modules, its very easy to install as many different MPI implimentations (and their corresponding MAN pages, etc.) as you want and then define multiple MPI "modules" (that is, scripts within the environment-modules system) that each set the correct MANPATH and any other values. And I mention man pages only as an example -- the idea readily entends to binaries, libs, headers, what-have-you... Further, the use of environment-modules is a __de facto__ standard. The vast majority of (super-)computing centers, clusters, etc. where MPI is chiefly used also use environment-modules. Its popular at these locations exactly because it works so smoothly. Its a simple, easily understood, extensible, and elegant approach. And it provides end users with maximal flexibility and choice. To the best of my knowledge, not a *single* system on this planet uses alternatives for MPI. Its borderline moronic. Why would you folks want to ignore the hard-won wisdom of an entire field and go with some clunky, inferior alternatives-based approach when you can have something so much better? PS: Orion has very helpfully packaged environment-modules for Extras so its *very* easy for you folks to adopt... [Hint-hint...!] PPS: I'll be glad to discuss this further with anyone who has questions.
