m_mpi_proxy Module Reference

MPI halo exchange, domain decomposition, and buffer packing/unpacking for the simulation solver. More...

Functions/Subroutines
subroutine	s_initialize_mpi_proxy_module ()
	Allocates immersed boundary communication buffers for MPI halo exchanges.
impure subroutine	s_mpi_bcast_user_inputs ()
	Since only the processor with rank 0 reads and verifies the consistency of user inputs, these are initially not available to the other processors. Then, the purpose of this subroutine is to distribute the user inputs to the remaining processors in the communicator.
impure subroutine	s_mpi_send_random_number (phi_rn, num_freq)
	Broadcasts random phase numbers from rank 0 to all MPI processes.
subroutine	s_finalize_mpi_proxy_module ()
	Deallocates immersed boundary MPI communication buffers.

Variables
integer, dimension(:), allocatable, private	ib_buff_send
	This variable is utilized to pack and send the buffer of the immersed boundary markers, for a single computational domain boundary at the time, to the relevant neighboring processor.
integer, dimension(:), allocatable, private	ib_buff_recv
	q_cons_buff_recv is utilized to receive and unpack the buffer of the immersed boundary markers, for a single computational domain boundary at the time, from the relevant neighboring processor.
integer	i_halo_size
