Detailed Description
keeps the information about the structure of a full matrix
- Parameters:
-
para_env the parallel environment of the matrixes with this structure context the blacs context (parallel environment for scalapack), should be compatible wih para_env descriptor the scalapack descriptor of the matrixes, when using scalapack (ncol_block=descriptor(6), ncol_global=descriptor(4), nrow_block=descriptor(5), nrow_global=descriptor(3)) ncol_block number of columns of a scalapack block nrow_block number of rows of a scalapack block nrow_global number of rows of the matrix ncol_global number of rows first_p_pos position of the first processor (for scalapack) row_indices real (global) indexes of the rows (defined only for the local rows really used) col_indices real (global) indexes of the cols (defined only for the local cols really used) nrow_locals nrow_locals(i) number of local rows of the matrix really used on the processors with contextmepos(1)==i ncol_locals ncol_locals(i) number of local rows of the matrix really used on the processors with contextmepos(2)==i id_nr an identification number (guaranteed to be unique) ref_count reference count (see doc/ReferenceCounting.html) local_leading_dimension leading dimension of the data that is stored on this processor
readonly attributes:
- Parameters:
-
nrow_local number of local rows really used on the actual processor ncol_local number of local cols really used on the actual processor
- Note:
- use cp_fm_struct_get to extract information from this structure
