Is it Open MPI's executables that require the intel shared libraries at run time, or your application? Keep in mind the difference: 1. Compile/link flags that you specify to OMPI's configure script are used to compile/link Open MPI itself (including executables such as mpirun). 2. mpicc (and friends) use a similar-but-different set of flags to compile and link MPI applications. Specifically, we try to use the minimal set of flags necessary to compile/link, and let the user choose to add more flags if they want to. See this FAQ entry for more details: http://www.open-mpi.org/faq/?category=mpi-apps#override-wrappers-after-v1.0 > (2) After compiling and linking our in-house codes with open mpi > 1.4.3, we want to make a minimal list of executables for our codes > with some from open mpi 1.4.3 installation, without any dependent > on external setting such as environment variables, etc. > > I orgnize my directory as follows: > > parent--- > | > package > | > bin > | > lib > | > tools > > In package/ directory are executables from our codes. bin/ has > mpirun and orted, copied from openmpi installation. lib/ includes > open mpi libraries, and intel libraries. tools/ includes some c-shell > scripts to launch mpi jobs, which uses mpirun in bin/. FWIW, you can use the following OMPI options to configure to eliminate all the OMPI plugins (i.e., locate all that code up in libmpi and friends, vs. being standalone-DSOs): --disable-shared --enable-static This will make libmpi.a (vs. libmpi.so and a bunch of plugins) which your application can statically link against. But it does make a larger executable. Alternatively, you can: --disable-dlopen (instead of disable-shared/enable-static) which will make a giant libmpi.so (vs. libmpi.so and all the plugin DSOs). So your MPI app will still dynamically link against libmpi, but all the plugins will be physically located in libmpi.so vs. being dlopen'ed at run time. > The parent/ directory is on a NFS shared by all nodes of the > cluster.

This option, as is probably pretty obvious :-), makes mpirun behave as if the --prefix option was specified on the command line, with an argument equal to the $prefix from configure. -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
