Hello Harald, please see: http://www.open-mpi.org/faq/?category=mpi-apps#why-no-rpath
One possibility with Your existing installation is to circumvent a libmpi* being used from the standard system library directories: just adapt Your mpi*-wrapper-data.txt files in /home/Computacional/harald/aplic/openmpi/1.2/share/openmpi Instead of: libs=-lmpi set it to: libs=/home/Computacional/harald/aplic/openmpi/1.2/lib/libmpi.a Of course, You may play with -rpath in conjunction with --with-wrapper-ldflags. More info on this in: http://www.open-mpi.org/faq/?category=mpi-apps#override-wrappers-after-v1.0 Hope this helps, Rainer On Thursday 08 November 2007 17:52, Harald Servat wrote: > Hello to all, > > I'm working on SGI Altix machine (IA64) which provides its own MPI > library.
