Open MPI (Installation and Setup)

Open MPI iWARP support is only available in Open MPI version 1.3 or greater.

Open MPI will work without any specific configuration via the openib btl. Users wishing to

performance tune the configurable options may wish to inspect the receive queue values. Those

can be found in the "Chelsio T4" section of mca-btl-openib-device-params.ini. Follow the

steps mentioned below to install and configure Open MPI.

i. If not alreay done, install mpi-selector tool.

ii. Download the latest stable/feature version of openMPI from OpenMPI website

,http://www.open-mpi.org

iii. Untar and change your current working directory to openMPI package directory.

iv. Configure and install as:

[root@host]# ./configure --with-openib=/usr CC=gcc CXX=g++ F77=gfortran

FC=gfortran --enable-mpirun-prefix-by-default --prefix=/usr/mpi/gcc/openmpi-

x.y.z/ --with-openib-libdir=/usr/lib64/ --libdir=/usr/mpi/gcc/openmpi-

x.y.z/lib64/ --with-contrib-vt-flags=--disable-iotrace

[root@host]# make

[root@host]# make install

The above step will install openMPI in /usr/mpi/gcc/openmpi-x.y.z/
