Re: [ptp-user] Problem with the PTP Target System Configuration on Mac O

[Greg Watson <g.watson@xxxxxxxxxxxx>]

Martin,

Your choice of target configuration determines which scripts get run. As you guessed, the scripts are used to formulate the command that gets issued to run the application, so the target configuration must match the type of installation you're trying to run the application on. So if you choose IBM Parallel Environment, then the system needs to have IBM Parallel Environment installed on it. If you have a system with Torque installed on it, then you would use the Torque-Generic-Batch configuration, etc.

We provide two target configurations that are most suited to running locally: Open MPI-Generic-Interactive and MPIC2-Generic-Interactive. Use the former of these if you have Open MPI installed on your Mac, use the latter if you have MPICH2. I would recommend using Open MPI as it has been more thoroughly tested.

Regards,
Greg

It seems to me, that the PTP system works in such a way, that -- depending on the choice of Target System Config -- one of these scripts in the directory .eclipsesettings is called which then is apparently supposed to generate either a batch file or something that finally should run the command line "mpirun …..".
