|
! Subroutine: psb_ssphalo
|
|
! This routine does the retrieval of remote matrix rows.
|
|
! Note that retrieval is done through GTBLK, therefore it should work
|
|
! for any matrix format in A; as for the output, default is CSR.
|
|
!
|
|
!
|
|
! 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.
