	Return my results via MPI. More...
template<typename T >
std::vector< T >	mpi_gather ()
	Reads all the MPI returns from mpi_return. NOTE that the output does not come with any order guarantees. This waits until all are finished. NOTE: This has NO robustness to losing nodes. https://mpitutorial.com/tutorials/dynamic-receiving-with-mpi-probe-and-mpi-status/. More...

	Send an int n to each request. Each requestor can use this to index into some data which they are assumed to know already. More...
