NAME
       BStri_solve - Multiply the matrix A(-1) by a block of vectors

INPUT PARAMETERS
       A      - a sparse matrix
       fact_A - a possibly incompletely factored version of A
       comm_A - the communication structure for A (fact_A)
       vec    - the block of vectors to multiply by
       pre_option
	      - the preconditioner to select PRE_ICC: incomplete Cholesky fac‐
	      torization PRE_ILU: incomplete LU factorization  PRE_SSOR:  Suc‐
	      cessive over relaxation PRE_BJACOBI: Block Jacobi
       BS     - the number of vectors in vec
       procinfo
	      - the usual processor stuff

OUTPUT PARAMETERS
       vec    - the resulting block of vectors

RETURNS
       void

NOTES
       Different code is used to multiply a single vector than is used to mul‐
       tiply a block of vectors (this improves efficiency).

SYNOPSIS
       void BStri_solve(BSpar_mat *A, BSpar_mat *fact_A, BScomm *comm_A, FLOAT *vec,
	 int pre_option, int BS, BSprocinfo *procinfo)
