Compositing mode nvIndeX


I’m trying to use Paraview with the NVIDIA IndeX plugin on a cluster but it runs slower than only one computer. I suppose it’s due to synchronization between each nodes before rendering on Paraview client.
I looked for a solution to disable that synchronization, and noticed NVIDIA IndeX has a setter/getter to define a compositing mode (Plugins/pvNVIDIAIndeX/include/nv/index/iconfig_settings.h) but it doesn’t seem to be used anywhere in the plugin’s source code, so I suppose it is always set to the default value (COMPOSITING_ALL: compositing on all nodes). Is there a way to configure that, either in the source code or in a config file ? Did I miss something in the Paraview client?
