Launching Parallel Programs

Topics include:

• selecting the machine to run on
• selecting executable to run
• supplying resource requirements (currently only number of processes, but this will include other requirements, such as scheduler information, later)
• debugger information

Creating a parallel launch configuration

1. Open the run configuration dialog (Run ->Run...) or click the run icon on the tool bar and select Run...
2. Create a new Parallel Application by clicking "Parallel Application" and then clicking on the "New" button below.

Setting parallel launch configuration parameters

1. Enter a name for the configuration in the "Name:" field. Here we use the same name as the project, MyCProject.
2. In the Main Tab:
   • Choose the project
   • Choose the executable from the project (see red arrows)

3. Select the Arguments tab
   • Enter any program arguments
   • Change working directory if necessary

4. Select the Parallel Tab
   • Choose the machine that the job will run on
   • 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."

5. Select the Debugger Tab
   • Select the Debugger that will control the parallel processes by selecting "SDM" (the PTP's Scalable Debug Manager) from the selection menu.
   • This will dismiss the Error at the top of the dialog which reports "[Debugger]: No debugger available."

Run the parallel job

1. Click on the Run button (or hit "Apply" to save these settings if you do not intend to launch immediately.)
2. The parallel program begins execution...
