old, deprecated interface cholesky_real: Cholesky factorization of a real symmetric matrix
- Parameters
-
na | Order of matrix |
a(lda,matrixCols) | Distributed matrix which should be factorized. Distribution is like in Scalapack. Only upper triangle is needs to be set. On return, the upper triangle contains the Cholesky factor and the lower triangle is set to 0. |
lda | Leading dimension of a |
matrixCols | local columns of matrix a |
nblk | blocksize of cyclic distribution, must be the same in both directions! |
mpi_comm_rows | MPI communicator for rows |
mpi_comm_cols | MPI communicator for columns |
wantDebug | logical, more debug information on failure |
- Returns
- succes logical, reports success or failure
