[Paraview] Find Data does not work on MPI

[Magician]

Hi Cory,


Thanks for your advice.
I tried some minimal cases again.

I executed pvserver with 2 CPUs, and generate a wavelet source.
Then I tried to select the points (RTData is >= 100).

The messages on Command Prompt are as follows:

My PV is v5.2.0 on Windows 7/8 64bit, just downloaded from Kitware’s download site.
MPI is Microsoft HPC Pack 2008 R2.

Perhaps the provided binary does not fully support MPI processing?
I should build PV with MPI by myself?
