Function Documentation

main()

int main	(	int	argc,
		char *	argv[]
	)

The Davidson takes the execution policy by base reference, so the MPI policy goes in where the serial one does for q3_gpu_cuda. The policy stays owned here, outliving every iterator built on it, and finalizes MPI from its destructor at the end of main.
