CLASSIFICATION: UNCLASSIFIED

Hi Robert,

Thank you for your email. We will pull that and start using that going 
forward.

We have a system with Tesla P100 and Joe had to manually change the CUDA 
library detection to get the compile going. Do you know anyone that was 
successful in getting the compilation going on system with Tesla P100 hardware 
without modifying the build script? Thank you.

thanks
-simon

Hi Simon,

The ability to enable CUDA support in the ParaViewSuperbuild has been added. 
You will need to have the latest superbuild, and enable `ENABLE_cuda` for 
support to be added.
