Subject: [OMPI users] OpenMPI 1.3.X Configuration for OFED
From: pat.o'bryant_at_[hidden]
Date: 2009-05-07 09:51:13

     I am in the process of building a production system with OpenMPI 1.3.2
with support for OFED. Is it necessary in the "configure" statement to
specify "--with-openib(=DIR)" to get OFED support? I have built a test
system with OpenMPI 1.3.2 and an "ompi_info" yields the output below. It
appears that InfiniBand support is installed even though I didn't use
    The installation of OFED used its "default" areas, of which there
appears to be a great number. If I have to specify the "openib" path I am
not sure what value should be used.

./ompi_info --all | grep openib
                 MCA btl: openib (MCA v2.0, API v2.0, Component v1.3.2)
