comm | - MPI communicator that will share the matrix Many br | |
bs | - block size of the matrix Many br | |
m,n,M,N | - local and/or global sizes of the left and right vector used in matrix vector products Many br | |
rmap | - local to global map for rows Many br | |
cmap | - local to global map for cols Many br |
Many br
Notes: See MATIS for more details Many brm and n are NOT related to the size of the map, they are the size of the part of the vector owned Many brby that process. The sizes of rmap and cmap define the size of the local matrices. Many brIf either rmap or cmap are NULL, than the matrix is assumed to be square Many br
