[ewg] RFC: Do we wish to take MPI out of OFED?

[Anatoly Greenblatt]

Hi,

I vote to remove.

This is our Open MPI team leader answer:

I think it should be taken out from the following reasons:
ompi related build errors or bugs can affect OFED release dates
many customers prefer their own mpi packages
almost all linux distros contain pre-compiled mpi rpms which can be
installed with yum/apt-get/...
having MPI as part of OFED comlicates its release process and scripts.


Regards,
Anatoly.

Hello,
In the EWG meeting yesterday there was a suggestion to take out all MPI 
packages including MPI tests out from OFED.

Here are some of the reasons for keeping MPI in or out of OFED.

Main reasons to take MPI out of OFED:
- MPI is not developed under OFA
- Need to synchronize between different projects
- Some customers prefer to install a different MPI version then the one 
in OFED

Main reasons to keep MPI in OFED:
- All participants test with the same MPI versions, and when installing 
OFED it is ensured that MPI will work fine with this version.
- Customers convenience in install (no need to go to more sites to get
MPI)
- MPI is an important RDMA ULP and although it is not developed in OFA 
it is widely used by OFED customers

Before we decide to do such a change I would like to get the more 
opinions from the comunity.

Thanks,
Tziporet
