I just spent some time going over this, along with Prof Hao, the author of Rmpi. You may simply have been missing the openmpi-bin package which provides tools like orterun -- Open MPI now needs this at startup. This may get added to configure tests in the future to alert users. With this openmpi-bin package installed, I could easily install Rmpi on Debian and Ubuntu using the distro's Open MPI packages. No need for local Open MPI builds. Also note this post on the Open MPI list: http://www.open-mpi.org/community/lists/devel/2012/04/10840.php Static builds may lead to loss of resources at runtime as you may have multiple copies running. | Thank you to Prof Ripley for pointing that out! I think it was shared | and dlopen options that kept preventing me from succeeding. I believe this advise to be incorrect. We have been using dynamically linked builds of Open MPI for several years on Debian with good success. I was involved in an overhaul of Debian's Open MPI packages around 2006/2007; the package has since been very well maintained by others.
