[openfabrics-ewg] rc3 installation issues.

Tue Apr 25 16:36:34 PDT 2006

Right now I don't have the resources to test OFED, especially all the
configurations that
you intent to support.  I am hoping to get some time 
to try it on at least one configuration, but I don't think I can test it
on all of the configurations
and kernels that you are trying to support. The way I understand it,
OFED supports every kernel.org
kernel since 2.6.12, plus Suse and RedHat and perhaps other distro
kernels ? Is that correct ?
What tests do you currently run on each configuration ? Do you have a
published test plan ?

It might be beneficial for you to stress test the rest of the OFED stack
using
Intel MPI, I use it to test my backport patches for the trunk and it
seems to be a pretty
good stress test. We could also let you have access to the Intel MPI
test suite,
which is a couple hundred MPI test programs. 

Would you like to use Intel MPI as part of your test suite for OFED ?

Woody,

The whole issue is to have as many people as possible participating in
the effort. We are running almost all the stack and I thought that if
you already running Intel MPI on gen2 it should be not a big effort to
run it on  OFED.

Intel MPI needs a stable uDAPL and supporting usermode verbs/uCMA and
such.
If you have that, then Intel MPI should work. If you want to get a copy
of Intel MPI
to use in your testing of OFED, I can put you in contact with our Intel
MPI lead and he can
provide you with the code and a license.

Please work with Vlad to make sure you have what you need in rc4.

Not yet. Last I heard, there was no uDAPL in OFED that is neeed by Intel
MPI. Maybe RC4.

Woody,

Are you testing Intel MPI on top of OFED?

The latest patches I have is for SVN 6509 on the trunk.
https://openib.org/svn/gen2/branches/backport-to-2.6.9/
infiniband-backport-svn6509-to-2.6.9-34.EL-kernel-fixups-00.diff
infiniband-backport-svn6509-to-2.6.9-34.EL-kernel-fixups-01.diff
infiniband-backport-svn6509-to-2.6.9-openib-drivers-02.diff
infiniband-backport-svn6509-to-2.6.9-openib-fixups-03.diff

I don't split the patches by component, but rather have one to strip out
the old IB
code in RedHat EL4.0, one to apply needed kernel changes to the RedHat
kernel,
one for the openib drivers, and one for openib fixups that are needed.

We plan to do a backport of uCMA for RC4.

Can you point me to your backport of uCMA for 2.6.9-34EL

Thanks,

Tziporet

Note that there are two uDAPL providers for OpenIB. One uses standard
sockets for connections (socket CM)

and the other uses CMA. I would suggest that you should include the
socket CM uDAPL provider even

if you do not have a backport for uCMA.

BTW. - My backport patches contain backport for uCMA for 2.6.9-34-EL if
you need an example.
