So the login node is the only one that has a window to the outside
world. I can't access the outside world from within an allocation.

So my script does:
  - Login Node:
    1) Get MPI Tarballs
  - 1 Compute node:
    0) Allocate a compute node to compile.
    1) Build/Install MPI builds
    2) Deallocate compute node
  - Login Node:
    1) Get MPI Test sources
  - N Compute Nodes:
    0) Allocate N compute Nodes to run the tests on
    1) Build/Install Tests
    2) Run the tests...
  - Login Node:
    0) Check to make sure we are all done (scheduler didn't kill the
job, etc.).
    1) Report results to MTT *

* This is what I am missing currently.

I currently have the "Reporter: IU Database" section commented out so
that once the tests finish they don't try to post the database, since
they can't see the outside world.
