! Subroutine: psi_idx_ins_cnvs
|
|
! Converts an index from global to local numbering.
|
|
! This routine is called while the descriptor is in the build state;
|
|
! the idea is that if an index is not yet marked as local, it is a new
|
|
! connection to another process, i.e. a new entry into the halo.
|
|
! But we still need the mask, because we have to take out the column indices
|
|
! corresponding to row indices we do not own (see psb_cdins for how this is used).
|
|
!
|
|
! Arguments:
|
|
! idxin - integer Required index s
|
|
! idxout - integer Output value (negative for masked entries)
|
|
! desc - type(psb_desc_type). The communication descriptor.
|
|
! info - integer. return code.
|
|
! mask - logical, optional Only do the conversion for specific indices.
