NAME
       BSbackward1 - Backward triangular matrix multiplication on a single
       vector

INPUT PARAMETERS
       A      - The sparse matrix
       x      - The input vector
       comm   - The communication structure for A
       procinfo
              - the usual processor information

OUTPUT PARAMETERS
       b      - on exit contains A*x

RETURNS
       void

NOTES
       We assume that A has no i-nodes or cliques

SYNOPSIS
       void BSbackward1(BSpar_mat *A, FLOAT *x, FLOAT *b,
         BScomm *comm, BSprocinfo *procinfo)
