+  * OpenHPC provides package aliases for these 3rd party libraries and utilities that can
+be used to install available libraries for use with the GNU compiler family toolchain.
+<code>
+# Install libs for all available GNU compiler family toolchain
+yum -y groupinstall ohpc-serial-libs-gnu
+yum -y groupinstall ohpc-io-libs-gnu
+yum -y groupinstall ohpc-python-libs-gnu
+yum -y groupinstall ohpc-runtimes-gnu
+# Install parallel libs for all available MPI toolchains
+yum -y groupinstall ohpc-parallel-libs-gnu-mpich
+yum -y groupinstall ohpc-parallel-libs-gnu-mvapich2
+yum -y groupinstall ohpc-parallel-libs-gnu-openmpi
+# things like
+# netcdf, hdf5, numpy and scipy for python, fftw, scalapack
+</code>
+Finish with installing Intel's Parallel Data Studio (icc/ifort).
+{{:cluster:install_guide-centos7.2-slurm-1.2-x86_64.pdf|install_guide-centos7.2-slurm-1.2-x86_64.pdf}}
+As user ''test''
+<code>
+module avail
+module spider
+which mpicc
+module load gnu/5.4.0
+module load openmpi/1.10.4
+which gcc
+which mpicc
+mpicc -O3 /opt/ohpc/pub/examples/mpi/hello.c
+cp /opt/ohpc/pub/examples/slurm/job.mpi .
+which prun
+find /opt/ohpc/pub -name prun
+module spider prun
+module load prun/1.1
+which prun
+sbatch job.mpi
+squeue
+</code>
+You do need to install the Infiniband section so you can run over ethernet with OpenMPI
+<code>
+  yum  -y groupinstall "Infiniband Support"
+  yum -y install infinipath-psm
+  systemctl enable rdma
+  systemctl start rdma
+# recipe is missing this: flavor openmpi
+  yum -y --installroot=/data/ohpc/images/centos7.2 install libibverbs opensm-libs infinipath-psm
+# remake vnfs
+</code>
+The following shows up when running MPI over ethernet
+<code>
+[prun] Master compute host = n29
+[prun] Resource manager = slurm
+[prun] Launch cmd = mpirun ./a.out
+--------------------------------------------------------------------------
+[[49978,1],4]: A high-performance Open MPI point-to-point messaging module
+was unable to find any relevant network interfaces:
+Module: OpenFabrics (openib)
+  Host: n31
+Another transport will be used instead, although this may result in
+lower performance.
