Hi Jean,
<div class=""><br class="">
</div>
<div class="">Thanks for the feedback. Can you roughly estimate the time it took to generate the ghost cells? And was the time strongly correlated to the number of cores used?</div>

I tried running benchmarks yesterday with my reader, and a model that came close, but was not not quite as big as yours. I have several models with 300-400 millions cells. Using the GhostCellGenerator turning OFF the "use GlobalNodeIds" option would always
crash, so I could not compare execution with and without it. I tried with different core counts ranging from 24x8 to 48*8 cores. Memory usage before applying the filter would show 20Gb out of 32Gb (per node) used, so I don't think I was crashing on out-of-memory
errors.<br class="">
<br class="">
I have global Ids which are all consecutive, so I cannot answer your 2nd question, but my feeling is that uniqueness is the only necessary condition.<br class="">
