[OMPI users] mpirun: symbol lookup error: mpirun: undefined symbol: orte_xml_fp
Hi all, It's a bit awkward for me to ask, because I'm not only newbie in parallel programming but also in Linux system, but i've but searching for long enough to loose any hopes. My problem is, when I try to run compiled code with "mpirun" I get output: mpirun: symbol lookup error: mpirun: undefined symbol: orte_xml_fp I can compile code with "mpicc" (i write in C) and it runs, but only on one CPU ( I have Athlon X2 64bit, dual core ). There is no difference when I write "mpirun", "mpiexec" or "orterun" (but that's normal, isn't it?). It doesn't matter what I'm trying to run; I get that output just by typing it into console. As I said, I know basics with linux and even adding some libs into sys path is something which I still don't know ( and don't how much time to read about). I've attached things which maybe helpful ( output from "./configure", "make all", "make install" ). I'm using Linux Mint 8 ( Kernel Linux 2.6.31-20-generic). Have two CPU cores AMD Athlon Dual-Core QL-60. Much appreciate any help :) Cheers, David Laszuk ompi-output.tar.bz2 Description: BZip2 compressed data
[OMPI users] Building 1.4.x on mac snow leopard with intel compilers
I'm having problems building a working version of openmpi 1.4.1/2 on a new Apple Mac Pro (dual quad-core nehalem processors) running snow leopard (10.6.3) with the Intel 11.1 compilers. I've tried the Intel 11.1.084 and 11.1.088 versions of the compilers. Everything appears to build just fine and some mpi test programs run but whenever I run a program with an MPI_Reduce() or MPI_Allreduce() I get a segfault (even with np=1). I'm building openmpi with: configure -without-xgrid -prefix= CC=icc CXX=icpc F77=ifort FC=ifort When I build openmpi 1.4.1/2 with the GNU 4.3 compilers (installed via macports) using: configure -without-xgrid -prefix= CC=gcc-mp-4.3 CXX=g++-mp-4.3 F77=gfortran-mp-4.3 FC=gfortran-mp-4.3 all my mpi tests (6000+) run fine. Any help would be appreciated. Thanks, Mike

Re: [OMPI users] Building 1.4.x on mac snow leopard with intel compilers
Mike, Are you sure that you are getting the openmpi that you built and not the one supplied w/ OS X. I use modules to make sure that I am getting the openmpi version I build instead of the OS X suppleid version.
