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 factorization PRE_ILU: incomplete LU factorization PRE_SSOR: Successive 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 multiply 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)
