In short, that won’t work.<BR>

Subject: [Paraview-developers] MPI Parallel Sorting<BR>
<BR>
Folks,<BR>
<BR>
I am looking at the long standing feature request to add support for<BR>
sorting in the spreadsheet view. Our use case is that we have a large<BR>
array is distributed among N processes.<BR>
We want to end up with that array sorted but still distributed among<BR>
all processes. Most implementations I am looking at end up creating<BR>
one large sorted array on one of nodes. Does anyone know any approach<BR>
that avoids this generation of a large array on the root node?<BR>
<BR>
