hello again,

thanks Greg!  always with the appropriate response.

now how do you create  "a Parallel Application run configuration"?

Just to clarify, PTP supports the following MPI implementations:

Open MPI - launching and debugging

MPICH2 - launching only

To launch either of these, you need to create a Parallel Application run configuration, then choose the appropriate target configuration (either Open MPI-Generic-Interactive or MPICH2-Generic-Interactive).

OpenMP is a different programming model that uses threads. The PTP debugger supports debugging threaded MPI applications, so hybrid MPI/OpenMP programs should work.

hello,

yes i noticed that,  which is why i downloaded openmpi, i already worked on openMP but i also need MPI for some sort of hybrid research project.

all of my OpenMP work was done on eclipse-ptp,  so it would be very convenient to have MPI runing as well with a variable number of processors.

hi there,

Eclipse doesn't  support mpich well.  Buggers will come up when you try to debug your codes. So you had better use openmpi instead of mpich.  Please refer to parallel development user manual to see how to develop parallel program.
