Dear All I am trying to get openmpi-1.1.2 to work on AIX 5.3 / power5. :: Compilation seems to have worked with the following sequence: ==================================================================== setenv OBJECT_MODE 64 setenv CC xlc setenv CXX xlC setenv F77 xlf setenv FC xlf90 setenv CFLAGS "-qthreaded -O3 -qmaxmem=-1 -qarch=pwr5x -qtune=pwr5 -q64" setenv CXXFLAGS "-qthreaded -O3 -qmaxmem=-1 -qarch=pwr5x -qtune=pwr5 -q64" setenv FFLAGS "-qthreaded -O3 -qmaxmem=-1 -qarch=pwr5x -qtune=pwr5 -q64" setenv FCFLAGS "-qthreaded -O3 -qmaxmem=-1 -qarch=pwr5x -qtune=pwr5 -q64" setenv LDFLAGS "-Wl,-brtl" ./configure --prefix=/ist/openmpi-1.1.2 \ --disable-mpi-cxx \ --disable-mpi-cxx-seek \ --enable-mpi-threads \ --enable-progress-threads \ --enable-static \ --disable-shared \ --disable-io-romio ==================================================================== :: After the compilation I ran make check and all 11 tests passed successfully. :: Now I'm trying to run the following command just for test: # mpirun -hostfile /gpfs/MICHAEL/MPI_hostfiles/mpinodes_b41-b44_1.asc -np 2 /usr/bin/hostname - The file /gpfs/MICHAEL/MPI_hostfiles/mpinodes_b41-b44_1.asc contains 4 hosts: r1blade041 slots=1 r1blade042 slots=1 r1blade043 slots=1 r1blade044 slots=1 - The mpirun command eventually hangs with the following message: [r1blade041:418014] poll failed with errno=25 [r1blade041:418014] opal_event_loop: ompi_evesel->dispatch() failed. - In this state mpirun cannot be killed by hitting <ctrl-c> only a kill -9 will do the trick. - While the mpirun still hangs I can see that the "orted" has been launched on both requested hosts. :: I turned on all debug options in openmpi-mca-params.conf. The output for the same call of mpirun is in the file mpirun-debug.txt.gz. |

:: As I am completely new to openmpi (I have some experience with lam) I am lost at this stage. I would really appreciate if someone could give me some hints as to what is going wrong and where I could get more info.
