###Brief
|
|
|
|
|
|
|
|
Initial mesh is partitioned using one of available partitioner. Then the number of cell elements and connected components is computed.
|
|
|
|
|
|
|
|
##Description
|
|
|
|
|
|
|
|
Test loads one of provided serial or distributed meshes.
|
|
|
|
Different partitioner may be used to (re)partition the mesh.
|
|
|
|
Simple statistics is computed: number of cells, number of connected components.
|
|
|
|
|
|
|
|
##Arguments
|
|
|
|
|
|
|
|
The test have two required parameters and one optional.
|
|
|
|
|
|
|
|
First parameter is the input mesh file.
|
|
|
|
|
|
|
|
The second parameter is the desired partitioner:
|
|
|
|
|
|
|
|
```
|
|
|
|
0 - Inner_RCM
|
|
|
|
1 - Parmetis
|
|
|
|
2 - Zoltan_HSFC
|
|
|
|
3 - Zoltan_RIB
|
|
|
|
4 - Zoltan_RCB
|
|
|
|
5 - Zoltan_PHG
|
|
|
|
6 - Zoltan_Scotch
|
|
|
|
7 - Zoltan_Parmetis
|
|
|
|
-1 - No partitioner
|
|
|
|
```
|
|
|
|
|
|
|
|
Optional second parameter is used to define ParMETIS action (default: 0):
|
|
|
|
```
|
|
|
|
0 - Partition
|
|
|
|
1 - Repartition
|
|
|
|
2 - Refine
|
|
|
|
```
|
|
|
|
|
|
|
|
##CMake tests
|
|
|
|
|
|
|
|
If USE_MPI is activated and CMake have variable ${MPIEXEC} set up correctly then the test will seed pmesh_test001_*_np_* tests for available partitioners and np=2,4 with included Menger Sponge 9x9x9 mesh. |
