ThreadLevel

enum class kamping::ThreadLevel : int

strong

MPI thread support levels defining the allowed concurrency of MPI calls relative to application threads. You can obtain the underlying values by casting the enum value to int.

Enumerator
single	No thread support; only one thread may execute, and only the main thread can make MPI calls.
funneled	Only the main thread will make MPI calls, but the application may be multi-threaded.
serialized	Multiple threads may exist, but only one at a time will make MPI calls (calls are serialized).
multiple	Full thread support; multiple threads may call MPI concurrently.
