Hello, OpenMPI output issues when using IBM AIX 5.3
We have recently installed OpenMPI 1.1.2 (see attacched, ompi_inf -a output for detail). on an IBM AIX 5.3. We had no problem during installation and configration. "ompi_info -a" runs with no problem. Running our application we got no error or output from "printf", or "cout". So, we wrote a simple 10 line program, which basicly setup mpi and does a "printf" and "cout". We still didn't get any output from this program, when using MPI in a none debug mode. I find out that we get the output from this simple program if we add "--debug-daemons" to the mpirun commands. But, still for a more complex program we don't get any output even with the "--debug-daemons" flag. My question are 1 - why do we need a debug flag to get any output? 2 - does anyone has any recommendation on how to build an mpi application for IBM AIX 5.3 to get the output, without any debug flag. Thanks for any comments Nader,
