Functions/Subroutines
impure subroutine	s_initialize_mpi_proxy_module
	Computation of parameters, allocation procedures, and/or any other tasks needed to properly setup the module.
impure subroutine	s_mpi_bcast_user_inputs
	Since only processor with rank 0 is in charge of reading and checking the consistency of the user provided inputs, these are not available to the remaining processors. This subroutine is then in charge of broadcasting the required information.
impure subroutine	s_mpi_gather_spatial_extents (spatial_extents)
	This subroutine gathers the Silo database metadata for the spatial extents in order to boost the performance of the multidimensional visualization.
impure subroutine	s_mpi_defragment_1d_grid_variable
	This subroutine collects the sub-domain cell-boundary or cell-center locations data from all of the processors and puts back together the grid of the entire computational domain on the rank 0 processor. This is only done for 1D simulations.
impure subroutine	s_mpi_gather_data_extents (q_sf, data_extents)
	This subroutine gathers the Silo database metadata for the flow variable's extents as to boost performance of the multidimensional visualization.
impure subroutine	s_mpi_defragment_1d_flow_variable (q_sf, q_root_sf)
	This subroutine gathers the sub-domain flow variable data from all of the processors and puts it back together for the entire computational domain on the rank 0 processor. This is only done for 1D simulations.
impure subroutine	s_finalize_mpi_proxy_module
	Deallocation procedures for the module.

Detailed Description

This module serves as a proxy to the parameters and subroutines available in the MPI implementation's MPI module. Specifically, the role of the proxy is to harness basic MPI commands into more complex procedures as to achieve the required communication goals for the post-process.

Function/Subroutine Documentation

s_finalize_mpi_proxy_module()

impure subroutine m_mpi_proxy::s_finalize_mpi_proxy_module

Deallocation procedures for the module.

s_initialize_mpi_proxy_module()

impure subroutine m_mpi_proxy::s_initialize_mpi_proxy_module

Computation of parameters, allocation procedures, and/or any other tasks needed to properly setup the module.

Here is the caller graph for this function:

s_mpi_bcast_user_inputs()

impure subroutine m_mpi_proxy::s_mpi_bcast_user_inputs

Since only processor with rank 0 is in charge of reading and checking the consistency of the user provided inputs, these are not available to the remaining processors. This subroutine is then in charge of broadcasting the required information.

s_mpi_defragment_1d_flow_variable()

impure subroutine m_mpi_proxy::s_mpi_defragment_1d_flow_variable	(	real(wp), dimension(0:m), intent(in)	q_sf,
		real(wp), dimension(0:m), intent(inout)	q_root_sf )

This subroutine gathers the sub-domain flow variable data from all of the processors and puts it back together for the entire computational domain on the rank 0 processor. This is only done for 1D simulations.

Parameters

q_sf	Flow variable defined on a single computational sub-domain
q_root_sf	Flow variable defined on the entire computational domain

Here is the caller graph for this function:

s_mpi_defragment_1d_grid_variable()

impure subroutine m_mpi_proxy::s_mpi_defragment_1d_grid_variable

This subroutine collects the sub-domain cell-boundary or cell-center locations data from all of the processors and puts back together the grid of the entire computational domain on the rank 0 processor. This is only done for 1D simulations.

Here is the caller graph for this function:

s_mpi_gather_data_extents()

impure subroutine m_mpi_proxy::s_mpi_gather_data_extents	(	real(wp), dimension(:, :, :), intent(in)	q_sf,
		real(wp), dimension(1:2, 0:num_procs - 1), intent(inout)	data_extents )

This subroutine gathers the Silo database metadata for the flow variable's extents as to boost performance of the multidimensional visualization.

Parameters

q_sf	Flow variable defined on a single computational sub-domain
data_extents	The flow variable extents on each of the processor's sub-domain. First dimension of array corresponds to the former's minimum and maximum values, respectively, while second dimension corresponds to each processor's rank.

Here is the caller graph for this function:

s_mpi_gather_spatial_extents()

impure subroutine m_mpi_proxy::s_mpi_gather_spatial_extents

(

real(wp), dimension(1:, 0:), intent(inout)

spatial_extents

)

This subroutine gathers the Silo database metadata for the spatial extents in order to boost the performance of the multidimensional visualization.

Parameters

spatial_extents

Spatial extents for each processor's sub-domain. First dimension corresponds to the minimum and maximum values, respectively, while the second dimension corresponds to the processor rank.
