Multi-GPU support for Flex? Availability of CUDA source?

I’m currently making a particle simulator in Flex. It does not run in real time - instead the particle positions are saved at each timestep, then postprocessed at the end into a video.

One bottleneck is that Flex doesn’t seem to have Multi-GPU support for just the simulation - or at least I haven’t found any documentation that says otherwise.


  • Does Flex have multi-GPU support for the solver?
  • If not, how can I apply to get the CUDA source so I can add it myself? I suspect it would be fairly straight-forward for my specific use-case.
