| = Proposal for Improving MPI support in Fedora =
| |
|
| |
| '''Observation:'''
| |
|
| |
| People are increasingly using MPI to solve scientific and engineering problems. While its still a niche market, its steadily growing. Networks of workstations and small clusters have become quite common. And cheaper computers is only making it more common.
| |
|
| |
| '''Goal:'''
| |
|
| |
| It would be nice to provide, through Fedora Extras, a few different MPI implementations which can be installed with a single command
| |
| <pre>
| |
| yum install mpich2 openmpi ...
| |
| </pre>
| |
| and then operate them side-by-side without worries about conflicts. In my opinion, there are no good reasons why Fedora users should be "stuck" with LAM and forced to fight with from-source builds for other MPI implementations. We easily ''can'' and therefor ''should'' do better!
| |
|
| |
| '''Proposal:'''
| |
|
| |
| On a large number sites (ranging from "supercomputing centers" right through through medium and small cluster installs), admins have adopted the "modules" or [http://modules.sourceforge.net/ environment-modules] software to easily and gracefully handle situations with multiple simultaneous installs of various compilers and/or libraries. The environment-modules system has proven itself to be a solid, general, workable, and extensible framework. While I don't suggest that Fedora (or even Fedora Extras) adopt environment-modules wholesale for all sorts of problems, the simultaneus installation of multiple MPI implementatons is a situation that just '' '''begs''' '' for an environment-modules solution.
| |
|
| |
| The alternatives approach suggested by others is, in my opionion, clearly inferior to environment-modules since:
| |
|
| |
| * where does one put the man pages for each implementaton?
| |
| * the alternatives setup is NOT easily extended to multiple different compilers
| |
| * alternatives has the concept of one implementation being preferred to all others and this is unnecessary/pointless in the context of multiple MPI implemations
| |
|
| |
| With the recent addition of environment-modules to Fedora Extras, I'd like to see it used to solve the current multiple-MPI-implementations deadlock.
| |

I'm a Fedora Extras volunteer mostly interested in scientific computing, data acquisition and analysis, parallel computing and clusters, and related topics. I think Fedora is a good platform for these activities and would like to see it improve with the addition of more easy-to-use packages. For further discussion, please see the Fedora ["Extras/SIGs/SciTech"] .
