Functions/Subroutines |
| subroutine | SpMtx_arrangement::SpMtx_arrange (M, arrange_type, sort, nnz, nrows, ncols) |
| subroutine | SpMtx_arrangement::SpMtx_consolidate (M, add) |
| subroutine | SpMtx_arrangement::SpMtx_scale (M, A_ghost) |
| subroutine | SpMtx_arrangement::SpMtx_unscale (M) |
| subroutine | SpMtx_arrangement::SpMtx_build_refs (M, noffdels, rowstart, colnrs, colstart, rownrs) |
| subroutine | SpMtx_arrangement::SpMtx_build_refs_symm (A, noffdels, rowstart, colnrs, sortdown, diagstrong) |
| | build matrix reference arrays: for quick strong row reference, symmetric matrix case: rowstart(1:n+1), colnrs(1:noffdels)
|
| subroutine | SpMtx_arrangement::SpMtx_roughly_aggregate (A, aggr, neighood, maxaggrsize, alpha) |
| | Finding rough aggregates.
|
| subroutine | SpMtx_arrangement::SpMtx_Build_lggl (A, A_ghost, M) |
| recursive subroutine | SpMtx_arrangement::SpMtx_addFront (sendmask, A, M, i, p, ol) |
| | A helper procedure for marking all nodes within overlap distance in distribution mask.
|
| subroutine | SpMtx_arrangement::SpMtx_distributeWithOverlap (A, b, M, ol) |
| | Distribute assembled matrix and RHS vector from master to slaves; distribute by taking overlap into account NOTE: as a sideeffect, the returned matrix is arranged by rows.
|
| subroutine | SpMtx_arrangement::SpMtx_build_ghost (clr, ol, A, A_ghost, M, clrorder, clrstarts) |
| | Calculates overlap and then figures out which vector values need to be exchanged and which matrix values must be used in parallel matrix-vector multiplication and first level preconditioner.
|
| subroutine | SpMtx_arrangement::SpMtx_build_ghost_v01 (clr, ol, A, A_ghost, M, clrorder, clrstarts) |
| subroutine | SpMtx_arrangement::SpMtx_buildAdjncy (A, nedges, xadj, adjncy) |
| subroutine | SpMtx_arrangement::SpMtx_buildAggrAdjncy (A, aggr, maxaggrsize, nedges, xadj, adjncy) |
| | Subroutine to build aggregates' adjacency.
|
| subroutine | SpMtx_arrangement::SpMtx_SymmTest (A, eps) |
