[openib-general] Trying to compile mvapich RHEL4U3 for ib.

Hello Roger,

Thanks for trying out MVAPICH-0.9.7. Currently, we don't have any
machine with RHEL4U3. We are installing two machines with RHEL4U3 and we
will try out MVAPICH on that as soon as possible.

The verbs `ibv_get_device_list' was introduced before the 1.0 branch.
So, if you have either OpenIB installed from the trunk or from the 1.0
branch, you _should_ be able to see this verb in the library.

I am wondering if you are trying out the default versions of the OpenIB
rpms on RHEL4U3?

This is also due to a verb change made a while back to the
ibv_create_cq. I believe this version of mvapich-gen2 source rpm was
created against the version of userspace support which is present in the
very same .src.rpm (you may install those if you want, though they are a
little old now). The userspace verbs changed after this src rpm was
created.

Yes, it seems that the RPM you have installed is from somewhere in
between the ibv_create_cq verb change and the later introduction of the
ibv_get_device list verb.

I'm wondering if you could try it out with the latest 1.0 branch of
OpenIB? In addition, we will get back to you asap with our testing on
RHEL4U3.

Thanks,
Sayantan.
