Chapter Introduction | ||
Z01AAFP | Defines two-dimensional logical processor grid (Library Grid) and returns the BLACS context | |
Z01ABFP | Undefines logical processor grid and invalidates the BLACS context initialised by Z01AAFP | |
Z01ACFP | Root processor identifier | |
Z01AEFP | Used in creating processes outside the default library mechanism, allows multigridding, used in more advanced applications | |
Z01BAFP | Row and column indices of the root processor within the logical grid | |
Z01BBFP | Identifies logical processors in context in the two-dimensional grid declared by Z01AAFP | |
Z01BEFP | Topology to be used by BLACS for broadcasting and global operations | |
Z01BGFP | Information about MPI tasks | |
Z01CAFP | Number of rows or columns of matrix held locally on a given processor when the matrix is distributed in the cyclic two-dimensional block fashion (NUMROC) | |
Z01CBFP | Length of the workspace for F08AEFP (PDGEQRF) and F08AFFP (PDORGQR) | |
Z01CCFP | Length of the workspace for F08AGFP (PDORMQR) | |
Z01CDFP | Process coordinate which possesses the entry of a distributed matrix specified by a global index (INDXG2P) | |
Z01CEFP | Length of the workspace for F08FEFP (PDSYTRD) | |
