Harini, you can install OpenMPI which is packaged for your distribution of Linux, for examply on SuSE use zypper install openmpi or the equivalent on Redhat/Ubuntu
You probably will not get the most up to date Openmpi version, but you will get the library paths set up in /etc/ld.so.conf.d/ and the mpi chooser installed Once you have this version of OpenMPI working properly you should compile and install your own latest version. I just checked - the latest version for SuSE 12.1 in the repository science/openSUSE is 1.4.5 On 16/03/2012, Gustavo Correa <g...@ldeo.columbia.edu> wrote: > > On Mar 16, 2012, at 8:51 AM, Addepalli, Srirangam V wrote: > >> This usually means you library path is not updated to find mpilibrarues. >> You can fix this many ways, basic two steps are >> >> 1.
