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 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

void

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

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