BSmake_off_map(3)                BlockSolve95                BSmake_off_map(3)

NAME
       BSmake_off_map - Generate a mapping from global rows to processor id

INPUT PARAMETERS
       offset - the offset of the local processor in the global numbering
       procinfo
              - the usual processor information
       max    - the number of global rows

RETURNS
       the mapping

NOTES
       For example, processor 0 has 10 rows and an offset of 0, processor 1
       has 3 rows and an offset of 10 and processor 2 has 4 rows and an offset
       of 13 (there are 3 processors and 17 rows).  The offset mapping (see
       BSsparse.h) would have the offsets in sorted order with the
       corresponding processor id.  In this way, given a global row number,
       one could determine the processor on which it lies.

SYNOPSIS
