! Figure out who owns global indices.

! Arguments:

! nv - integer Number of indices required on the calling

! idx(:) - integer Required indices on the calling process.
|
||||
! Note: the indices should be unique!
|

! iprc(:) - integer(psb_ipk_), allocatable Output: process identifiers for the corresponding
|
||||
! indices
|
||||
! desc_a - type(psb_desc_type). The communication descriptor.

! info - integer. return code.
