[Paraview-developers] Parallel execution of vtkPEnSightGoldBinaryReader

[Favre Jean]

Hello developers

I am seeing ParaView crash when running in parallel to read EnSight Gold Binary rectilinear grids.

I think I have identified the problem to be on line 1520 of vtkPEnSightGoldBinaryReader.cxx

where the temporary array "scalarsRead" is allocated to read the full scalar fields (even though we should be distributing the array amongst pvservers). The array "scalars" is correctly dimensioned to only hold the subset, but then a loop over ALL nodes is executed to stuff the big array into the smaller one. Resulting in crashes.

Can someone confirm of known problems with EnSight Gold in parallel, or am I off in my analysis?
