Donnie, |

I think the real solution here is to use modules ( |
3 |
http://modules.sourceforge.net ) to handle the different versions of mpi. I |
4 |
filed a bug about using this for switching alternate virtuals a couple years |
5 |
ago, but nobody seemed to be particularly interested. I've got a grad student |
6 |
working on something to let users switch between mpi for gcc and mpi for the |
7 |
portland group compilers. I am most certainly not the right person to do the |
8 |
heavy lifting on this, but I do have an ebuild for modules I could contribute to |
9 |
the cause. |
