Method MPI.Init()

Method Init

void Init()

Description

Initializes MPI. MPI in Pike will auto-initialize once the first MPI-operation is called. You can call this function to initialize the parallel MPI at a specific time, since initialization is a collective operation and will block the process until all member processes of the parallel program are present.

Example

int main() {
	MPI.Init();
	write("I am process %d of %d.\n", MPI.world->rank,
	      MPI.world->size);
	MPI.Finalize();
	return 0;
}
