Hi folks,
<div class=""><br class="">
</div>
<div class="">I have a few questions about the new ghost cell generator filter (vtkPUnstructuredGridGhostCellsGenerator) that I already asked in a different context. Since I haven’t really resolved any of the issues yet, I took the liberty to post the questions
here again:</div>
<div class=""><br class="">
<div class="">- The docs indicate that the filter might perform faster if global point ids are available. Does anyone have an estimate about how much faster we are talking here?</div>
<div class="">- How can I make global point ids available that are suitable for this filter?<br class="">
- Is it possible/feasible/sensible to call this filter directly from within our custom reader plugin, such that users do not need to apply the filter manually each time?<br class="">
<br class="">
</div>
</div>
<div class="">Performance is critical in our case. We use a custom reader plugin to build our unstructured VTK grids using voxels. However, when using ~600 cores to visualize a 1 billion-cell grid, the “Generate Ghost Cells” plugin ran for >15 minutes without
results, after which we aborted since it is just not feasible anymore. Therefore I am very much interested in the expected performance impact of using global point ids.</div>

<div class="">Thanks a lot in advance</div>
