Bugs related to using MPI and SMP together

There is a bug with PointDataToCellData when using MPI and SMP together.

How to reproduce (with ParaView 5.4 release)

  • ./lib/paraview-5.4/mpiexec -np 2 ./bin/pvserver
  • ./bin/paraview
  • connect to server
  • Play test CategoricalColors.xml test
  • PointDataToCellData result is incorrect

mpitbb

This bug can of course be reproduced by compiling paraview with both options.
