I want to build OpenMPI-1.2.5 on my Infiniband cluster which has

I configured OpenMPI as:

And 'ompi_info | grep openib' only shows:
MCA btl: openib (MCA v1.0, API v1.0.1, Component v1.2.5)
I cannot see:
MCA mpool: openib (MCA v1.0, API v1.0, Component v1.0)
This is ok; we changed the name of the mpool component somewhere along
the way to be "rdma" (vs. "openib").
I see that you're compiling against the InfiniPath OFED -- is there a
reason you're not building the ipath Open MPI plugins? They should
give better performance than the openib stuff. Try
--with-psm=/usr/local/Cluster-Apps/infinipath/2.1/
(I don't know if you need to supply more to that path or not)
No idea why and if this will cause failure.
When I tried to run a MPI code with the option "--mca btl
openib,self", It
failed to run with the following messages:
