| class | ParallelLibrary |
| the ParallelLibrary class has special access priveleges in order to streamline implementation | |
Container class for the data associated with a single level of communicator partitioning.
A list of these levels is contained in ParallelLibrary (ParallelLibrary::parallelLevels), which defines all of the parallelism levels across one or more multilevel parallelism configurations.
| void clear | ( | ) | [inline] |
deallocate the communicators in this ParallelLevel
This appears to be more robust outside of the destructor due to interactions among managed deallocation and default deallocation (e.g., explicitly freeing a communicator and then default deallocating its handle).
