Yup, that would do it. Cray does static linking of their binaries for a reason. As Ralph suggests take a look at the LANL platform files. You will probably want to compile your app with -static or modify Open MPI's wrapper compilers to always link statically against the libraries needed for MPI. For example in prefix/share/openmpi/mpicc-wrapper-data.txt (mpicxx, mpif90) modify this line: libs=-lmpi to read: libs=-Wl,-Bstatic libs from libs_static-Wl,-Bdynamic Ex: libs=-lmpi libs_static=-lmpi -lopen-rte -lopen-pal -lm -lnuma -lpmi -lalpslli -lalpsutil -lugni -lxpmem -lrt -lnsl -lutil Becomes: libs=-Wl,-Bstatic -lmpi -lopen-rte -lopen-pal -lm -lnuma -lpmi -lalpslli -lalpsutil -lugni -lxpmem -lrt -lnsl -lutil -Wl,-Bdynamic libs_static=-lmpi -lopen-rte -lopen-pal -lm -lnuma -lpmi -lalpslli -lalpsutil -lugni -lxpmem -lrt -lnsl -lutil This will cause your application to link statically against mpi, ugni, xpmem, etc. -Nathan
