| Parameters: |
|
| ORDER_METHOD |
The order algorithm used by Zoltan is specified by this parameter.
Valid values are
"NODEND" (for nodal nested
dissection by ParMETIS or METIS),
"METIS" (same as NODEND with ORDER_TYPE = local),
"PARMETIS" (same as NODEND with ORDER_TYPE = global),
"SCOTCH", (parallel or sequential depending of the value of ORDER_TYPE) and
"NONE" (for no ordering).
|
| ORDER_TYPE |
"LOCAL" or "GLOBAL". If LOCAL is selected, then each processor
constructs a local (sub-)graph. All inter-processor edges are simply
ignored. The ordering arrays returned, rank and
iperm, are local permutation vectors in this case. If LOCAL is
selected, the serial version of the ordering routine is used,
i.e. Metis for ParMetis or Scotch for PT-Scotch. |
| ORDER_START_INDEX |
The start index for the permutation vectors rank and iperm.
Valid values are 0 and 1. |
| REORDER |
If this value is set to TRUE (non-zero), Zoltan assumes that the lists
of local and global ids are given as input to Zoltan_Order. Otherwise,
the id lists will be populated by Zoltan_Order. The permutation
of the ids will be the one produced by calling the query functions. |
| Default Values: |
|
|
ORDER_METHOD = NODEND |
|
ORDER_TYPE = GLOBAL |
|
ORDER_START_INDEX = 0 |
|
REORDER = FALSE |
