! File: psb_csphalo.f90
|

!
|
||||
! Subroutine: psb_csphalo psb_lcsphalo
|
||||
! This routine does the retrieval of remote matrix rows.
|
||||
! Retrieval is done through GETROW, therefore it should work
|
||||
! for any matrix format in A; as for the output, default is CSR.
|
||||
!
|
||||
! There is also a specialized version lc_CSR whose interface
|
||||
! is adapted for the needs of c_par_csr_spspmm.
|
||||
!
|
||||
! There are three possible exchange algorithms:
|
||||
! 1. Use MPI_Alltoallv
|
||||
! 2. Use psb_simple_a2av
|
||||
! 3. Use psb_simple_triad_a2av
|
||||
! Default choice is 3. The MPI variant has proved to be inefficient;
|
||||
! that is because it is not persistent, therefore you pay the initialization price
|
||||
! every time, and it is not optimized for a sparse communication pattern,
|
||||
! most MPI implementations assume that all communications are non-empty.
|
||||
! The PSB_SIMPLE variants reuse the same communicator, and go for a simplistic
|
||||
! sequence of sends/receive that is quite efficient for a sparse communication
|
||||
! pattern. To be refined/reviewed in the future to compare with neighbour
|
||||
! persistent collectives.
|
||||
!
|
||||
! Arguments:
|
||||
! a - type(psb_cspmat_type) The local part of input matrix A
|
||||
! desc_a - type(psb_desc_type). The communication descriptor.
|
||||
! blck - type(psb_cspmat_type) The local part of output matrix BLCK
|
||||
! info - integer. Return code
|
||||
! rowcnv - logical Should row/col indices be converted
|
||||
! colcnv - logical to/from global numbering when sent/received?
|
||||
! default is .TRUE.
|
||||
! rowscale - logical Should row/col indices on output be remapped
|
||||
! colscale - logical from MIN:MAX to 1:(MAX-MIN+1) ?
|
||||
! default is .FALSE.
|
||||
! (commmon use is ROWSCALE=.TRUE., COLSCALE=.FALSE.)

! data - integer Which index list in desc_a should be used to retrieve
|

! rows, default psb_comm_halo_

! File: psb_ssphalo.f90
|

!
|
||||
! Subroutine: psb_ssphalo psb_lssphalo
|
||||
! This routine does the retrieval of remote matrix rows.
|
||||
! Retrieval is done through GETROW, therefore it should work
|
||||
! for any matrix format in A; as for the output, default is CSR.
|
||||
!
|
||||
! There is also a specialized version ls_CSR whose interface
|
||||
! is adapted for the needs of s_par_csr_spspmm.
|
||||
!
|
||||
! There are three possible exchange algorithms:
|
||||
! 1. Use MPI_Alltoallv
|
||||
! 2. Use psb_simple_a2av
|
||||
! 3. Use psb_simple_triad_a2av
|
||||
! Default choice is 3. The MPI variant has proved to be inefficient;
|
||||
! that is because it is not persistent, therefore you pay the initialization price
|
||||
! every time, and it is not optimized for a sparse communication pattern,
|
||||
! most MPI implementations assume that all communications are non-empty.
|
||||
! The PSB_SIMPLE variants reuse the same communicator, and go for a simplistic
|
||||
! sequence of sends/receive that is quite efficient for a sparse communication
|
||||
! pattern. To be refined/reviewed in the future to compare with neighbour
|
||||
! persistent collectives.
|
||||
!
|
||||
! Arguments:
|
||||
! a - type(psb_sspmat_type) The local part of input matrix A
|
||||
! desc_a - type(psb_desc_type). The communication descriptor.
|
||||
! blck - type(psb_sspmat_type) The local part of output matrix BLCK
|
||||
! info - integer. Return code
|
||||
! rowcnv - logical Should row/col indices be converted
|
||||
! colcnv - logical to/from global numbering when sent/received?
|
||||
! default is .TRUE.
|
||||
! rowscale - logical Should row/col indices on output be remapped
|
||||
! colscale - logical from MIN:MAX to 1:(MAX-MIN+1) ?
|
||||
! default is .FALSE.
|
||||
! (commmon use is ROWSCALE=.TRUE., COLSCALE=.FALSE.)
|
||||
! data - integer Which index list in desc_a should be used to retrieve
|
||||
! rows, default psb_comm_halo_
|
||||
! psb_comm_halo_ use halo_index
|
||||
! psb_comm_ext_ use ext_index
|
||||
! psb_comm_ovrl_ DISABLED for this routine.

! File: psb_zsphalo.f90
|

!
|
||||
! Subroutine: psb_zsphalo psb_lzsphalo
|
||||
! This routine does the retrieval of remote matrix rows.
|
||||
! Retrieval is done through GETROW, therefore it should work
|
||||
! for any matrix format in A; as for the output, default is CSR.
|
||||
!
|
||||
! There is also a specialized version lz_CSR whose interface
|
||||
! is adapted for the needs of z_par_csr_spspmm.
|
||||
!
|
||||
! There are three possible exchange algorithms:
|
||||
! 1. Use MPI_Alltoallv
|
||||
! 2. Use psb_simple_a2av
|
||||
! 3. Use psb_simple_triad_a2av
|
||||
! Default choice is 3. The MPI variant has proved to be inefficient;
|
||||
! that is because it is not persistent, therefore you pay the initialization price
|
||||
! every time, and it is not optimized for a sparse communication pattern,
|
||||
! most MPI implementations assume that all communications are non-empty.
|
||||
! The PSB_SIMPLE variants reuse the same communicator, and go for a simplistic
|
||||
! sequence of sends/receive that is quite efficient for a sparse communication
|
||||
! pattern. To be refined/reviewed in the future to compare with neighbour
|
||||
! persistent collectives.
|
||||
!
|
||||
! Arguments:
|
||||
! a - type(psb_zspmat_type) The local part of input matrix A
|
||||
! desc_a - type(psb_desc_type). The communication descriptor.
|
||||
! blck - type(psb_zspmat_type) The local part of output matrix BLCK
|
||||
! info - integer. Return code
|
||||
! rowcnv - logical Should row/col indices be converted
|
||||
! colcnv - logical to/from global numbering when sent/received?
|
||||
! default is .TRUE.
|
||||
! rowscale - logical Should row/col indices on output be remapped
|
||||
! colscale - logical from MIN:MAX to 1:(MAX-MIN+1) ?
|
||||
! default is .FALSE.
|
||||
! (commmon use is ROWSCALE=.TRUE., COLSCALE=.FALSE.)
|
||||
! data - integer Which index list in desc_a should be used to retrieve
|
||||
! rows, default psb_comm_halo_
|
||||
! psb_comm_halo_ use halo_index
|
||||
! psb_comm_ext_ use ext_index
|
||||
! psb_comm_ovrl_ DISABLED for this routine.
