| <h1 id="top">Launching Parallel Programs</h1> |
| |
| <p>Topics include: |
| <ul> |
| <li>selecting the machine to run on |
| <li>selecting executable to run |
| <li>supplying resource requirements (currently only number of |
| processes, but this will include other requirements, such as scheduler information, later) |
| <li>debugger information |
| </ul> |
| <h2>The parallel launch configuration dialog</h2> |
| <ul> |
| <li>Open the run configuration dialog (Run ->Run...) |
| or click the run icon on the tool bar and select Run... |
| <li>Create a new Parallel Application by clicking "Parallel Application" and |
| then clicking on the "New" button icon. |
| <br> |
| <img src="images/launch1.gif"> |
| <p>Enter a name for the configuration in the "Name:" field. |
| Here we use the same name as the project. |
| <li>In the Main Tab:</li> |
| <ul> |
| |
| <li>Choose the project</li> |
| <li>Choose the executable from the project (see red arrows)</li> |
| <br><img src="images/launch2.gif"> |
| </ul> |
| <p> |
| <li>Select the Arguments tab |
| <ul> |
| <li>Enter any <i>program</i> arguments</li> |
| <li>Change working directory if necessary |
| |
| <p> |
| </li> |
| |
| </ul> |
| <li>Select the Parallel Tab</li> |
| <ul> |
| <li>Choose the machine that the job will run on |
| </li> |
| <li>Enter the number of processes to run, which was probably |
| set to "0" initially. Enter a value > 0. |
| This will dismiss the Error at the top of the |
| dialog which reports "[Parallel]: Value must be an Integer." |
| Actually, this should probably say "an integer greater than zero." |

| </li> |
| </ul> |
| <p> |
| <li>Select the Debugger Tab</li> |
| <ul> |
| <li>Select the Debugger that will control the parallel processes |
| by selecting "SDM" (the PTP's Scalable Debug Manager) from the selection menu. |
| </li> |
| <li>This will dismiss the Error at the top of the |
| dialog which reports "[Debugger]: No debugger available."</li> |
| <br><img src="images/launch5.gif"> |
| </ul> |
| <li>Click on Apply, then Run. |
| </li> |
| </ul> |
| <p> |
| <li>The parallel program begins execution... |
