Chapter Introduction | |
Z01AAFP | Defines a 2-d logical processor grid (Library Grid) and returns the BLACS context |
Z01ABFP | Undefines the logical processor grid and invalidates the BLACS context initialised by Z01AAFP |
Z01ACFP | Root processor identifier |
Z01ADFP | Used in creating processes outside the default library mechanism, allows multigridding, used in more advanced applications (PVM-based version only) |
Z01AEFP | Used in creating processes outside the default library mechanism, allows multigridding, used in more advanced applications (MPI-based version only) |
Z01BAFP | Row and column indices of the root processor within the logical grid |
Z01BBFP | Identifies logical processors in context in the 2-d grid declared by Z01AAFP |
Z01BDFP | Information about PVM tasks (PVM-based version only) |
Z01BEFP | Topology to be used by BLACS for broadcasting and global operations |
Z01BFFP | Enables debugging (PVM-based version only) |
Z01BGFP | Information about MPI tasks (MPI-based version only) |
Z01CAFP | Number of rows or columns of a matrix held locally on a given processor when the matrix is distributed in the cyclic 2-d block fashion (NUMROC) |
Z01CBFP | Length of the workspace for F08AEFP and F08AFFP |
Z01CCFP | Length of the workspace for F08AGFP |
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) |
