OMPI has been waiting for some git submodule work in Jenkins on AWS.
- Need someone to have someone to figure out why Jenkins doesn't like Jeff's PR.
- Anyone with github account for ompi team should have access.

Howard and Jeff have access to Jenkins on AWS. Part of the problem is that we don't have much expertise on Jenkins/AWS.

Merged
--recurse-submodulesupdate intoompi-scriptsJenkins script as first step. Let's see if that works. -
Modular thread re-write (noah)
