Parallel Engineering and Scientific Subroutine Library for AIX Version 2 Release 3: Guide and Reference

Argument Options

1. order = 'Row-major' or 'Column-major'

   The default is row-major natural ordering.

2. uplo = 'Upper triangular' or 'Lower triangular'
3. diag = 'Nonunit triangular' or 'Unit triangular'
4. scope = 'All', 'Row', or 'Column'
5. For broadcast topologies, top = '', 'I', 'D', 'H', 'S', 'F', 'M', 'T', '1', '2', '3', '4', '5', '6' '7', '8', or '9'

   For global topologies, top = '', 'H', 'F', 'T', '1', '2', '3', '4', '5', '6' '7', '8', or '9'

In the MPI implementation of the BLACS for Parallel ESSL for AIX, the broadcast and global topology arguments are ignored. In all cases, the equivalent MPI collective communication subroutine is used.
