| <p> |
| <h2 id="launch">Launching the MPI program with external program</h2> |
| <p>To run the program without using the PTP Runtime |
| or PTP Debugger, you can launch the 'mpirun' invocation |
| directly from eclipse. |
| <p>Set up the launch configuration for launching the |
| MPI program by configuring for "external tools." |
| Under the External tools menu |
| <img src="images/extToolsIcon.gif" border="1">, select External Tools |
| <p><img src="images/extToolsMenu.gif"> |
| <p>In the External Tools dialog, under Configurations, select Program |
| and select the "New" button. |
| <br><img src="images/extToolsDlg.gif"> |
| <p>Fill in the information to run 'mpirun' for example. |
| <br><img src="images/extToolsDlg2.gif"> |
| <br> |
| Use the buttons to fill in variables that point to locations |
| within your eclipse project, as shown above. |
| Click the "Run" button to execute it. |
| Output will be shown in the console window. |

| <h2 id="launch2">Launching the MPI program with the run configuration dialog</h2> |
| <ul> |
| <li>Open the run configuration dialog (Run...) |
| <li>Create a new C/C++ Local Application (or Local Application) |
| <li>Choose the project |
| <li>Enter the <i>full path</i> of the <code>mpirun</code> (or <code>mpiexec</code>) |
| command in the C/C++ Application (or Application) field |
| <li>Select the Arguments tab |
| <li>Enter the <code>mpirun</code> (or <code>mpiexec</code>) |
| arguments and the name of the executable |
| <li>Select Apply and then Run |
| |
| </ul> |
| <p>Limitations of the old way: |
| <ul> |
| <li>No indication of job or process status |
| <li>Cannot easily interact with a job scheduler |
| <li>Must have MPI installed on local machine |
| <li>No access to individual stdout of processes |
| <li>No ability to debug program |
| </ul> |
