Bulk Data Entry Identifies the number of groups into which the
specified MPI processes (-np) are divided.

| DDMNGRPS |
<Integer ≥ 1,
MAX, MIN,
AUTO, or -1> |
- Integer ≥ 1
- This parameter is supported for DDM Level 1
parallelization via:
- Task-based DDM runs.
- Global Search Option
(DGLOBAL).
- AUTO (Default) or
-1
- This option is only supported for the Task-based DDM
parallelization solution (first option mentioned above).
It will heuristically determine the number of groups
that are required for the specified model.
- MAX
- Automatically enforces the maximum number of groups
(which is equivalent to a pure Level 1 DDM task-based
parallelization run).
- MIN
- Automatically enforces the minimum number of groups
(which is equivalent to a purely geometric partition
based parallelization (Level 2 DDM) run).

Comments
- The
-ddmngrps run option is also available for this
feature. If both are defined simultaneously, then
PARAM,DDMNGRPS is overwritten by the options defined on
-ddmngrps run option.
