The File > Debug New Parallel Program dialog box (Classic TotalView) or the Add parallel program screen (MemoryScape) let you select a parallel configuration. If the default configurations that Perforce Software provides do not meet your needs, you can either overwrite these configurations or create new ones.

The default definitions for parallel configurations reside in the parallel_support.tvd file, located in your totalview/lib installation directory. For TotalView — and MemoryScape when used with TotalView — you can use the variable TV::parallel_configs to customize parallel configurations. For standalone -MemoryScape, you need to instead add any new configurations directly to the parallel_support.tvd file. Both these methods are discussed here.
