[openfabrics-ewg] Re: How to generate IBED releasesusing 1.0branch

[Shawn Hansen (shahanse)]

The rest of the team has been relatively silent on this thread the last
few days.

Before we announce anything to the public, I want to make sure the rest
of the team is on board with this description.

I'd like to hear from:

Reini/Silverstorm
Asaf/Voltaire
Matt/Sandia
Bryan/Pathscale

1.0branch

The way I see it is this:

Commonality between IBED and OpenFabrics Release 1.0:

   1. Both share the same user level code. (libraries, management
      utilities, opensm, uDAPL). The code is taken from 1.0 branch in
      both releases.
   2. Using bugzilla for bugs reporting.


Differences between IBED and OpenFabrics Release 1.0:

   1. OpenFabrics 1.0 release contains only the user level code while
      IBED release includes both user level and kernel modules.
   2. IBED release includes kernel modules that are not part of the
      Linux kernel (like iSER and RDS)
   3. IBED includes two MPI packages: OSU MPI and Open MPI.
   4. IBED release is packed in a convenient way for the end user.
   5. IBED supports existing distribution with older kernels (e.g.
      Redhat EL4 up2)


Thus really IBED contains the OpenFabrics release.

Not clear to me if Bryan is planning to prepare a separate OpenFabrics
release, or he to use the common part of IBED. I would recommend to do
it in the way and then the collaboration between both will be clear.

I hope this info is enough for the announcement mail. Note it is very
important to send this message today since we start to see questions
form different developers and I don't want that the answer will come
from engineering.
