[OMPI devel] IBM is now an Open MPI member

2017-01-13 Thread Jeff Squyres (jsquyres) 
We just had our quarterly vote for formal Open MPI membership.

Cisco nominated IBM for membership.

After voting, IBM was accepted to Open MPI for formal membership.  
https://www.open-mpi.org/about/members/ has been updated.

Congratulations, IBM!
