2.2 Running

To run the program in parallel, a charmrun executable was created by charmc. The flag +p is used to specify a number of processors to run the program on. For example:

> ./charmrun pgm +p4

This runs the executable pgm on 4 processors. For more information on how to use charmrun and set up your environment for parallel runs, see the CHARM++/CONVERSE Installation and Usage Manual.
