# IBM Platform MPI

This section describes how to set up a run configuration using IBM Platform MPI as a target system configuration for the Parallel Tools Platform (PTP).

When running an IBM Platform MPI program from PTP, first create a C/C++/Fortran project, and build it. For more information, see

- Introduction to creating MPI projects which includes information on building
- Setting up an MPI project with PTP's PLDT
- Synchronized Projects - creating and building projects on remote machines

As described in Running Parallel Programs, next create a run configuration via Run > Run Configurations ... and create a new Parallel Application.

The specifics for running an IBM Platform MPI program with PTP are specified on the Resources tab of the run configuration. For Target System Configuration, select IBM Platform MPI

Then specify a connection. If you have already specified a connection, e.g. for a Synchronized Project or a remote project, it will be selected already. If you are launching a local application, select the radio button for "Local."

> See Creating Remote Connections and Local Connections

> Note: To edit connection information after a connection has been created, e.g. to change user name or password, see Editing Remote Connections.

Fill in the IBM Platform MPI options you need. On the Basic Options tab here we specify 4 processes.

On the Advanced Options tab, other arguments can be specified; using a checkbox will fill in the checked argument.

Now continue with the run configuration setup for running your parallel application by specifying the Application program on the Application tab, and any other information required.
