SaveData (csv) on ExtractSubset and Multithreads (pvserver)
When SavingData into a csv file with a client/server using 4 threads results in duplicating some points resulting in a wrong number of line in the csv file.
A simple grid of 257*257 points should provide a csv file with 66050 (+1 header) If you run SaveData on 4 threads (mpiexec -np 4 pvserver -display :0.0 --force-offscreen-rendering) the csv file is 67601 (+1 header). Each direction is divided into 4 resulting in 3 duplicated points in each direction. This is annoying.
To be a bit more precise. I did this SaveData on a ExtractSubset filter applied on a cube to extract the top surface.
