BStri_solve(3) BlockSolve95 BStri_solve(3)

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

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

vec
- the resulting block of vectors

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)
