mxm is part of MOFED or you can download HPCX package (tarball of ompi + mxm) from http://mellanox.com/products/hpcx M On Thu, Jul 24, 2014 at 1:06 PM, madhurima madhunapanthula < erankima...@gmail.com> wrote: > > Hi, > > > I am trying to setup openmpi 1.8.1 on a system with infiniband. > > The configure option I am using is > > ./configure --enable-mpi-thread-multiple > > > After installation, it is not showing any openib BTL component when I use > the command: > 'ompi_info --param btl openib' > > > On the same machine, I have also installed openmpi 1.6.5.
