[Paraview] Performance of the CGNS Reader

[Richard Grenon]

Hello Mickael

I found some CGNS files having sizes from 3 Gb to 4 Gb. These files are 
available on my workstation through our internal network.

With your new CGNS Reader plugin, PV 4.1 is now able to load these files 
within more or less 3 mn, depending on the load of the network. This is 
very far from the 15 mn for a 1.3 Gb file when I made my first tests 
with the previous CGNS reader!

You did really a good job with this new CGNS reader plugin! It has now 
almost the same performance as Tecplot, and I hope it will be available 
in next PV releases.

The only drawback is that PV is always frozen while loading the file: if 
you mask the PV window, it becomes blank when you display it again, 
until the file is fully loaded. But this is the same thing for all 
readers, and an improvement for PV would be that all readers use a 
specific thread (or processor) so that a progress bar could always be seen.

Best regards

Richard
