Multi-GPU Particle Tracking & Immersed Boundary

Why doesn’t FluidX3D support multi-GPU passive particle tracking? What’s the biggest technical roadblock here? (e.g., data transfer between GPUs? Syncing particle positions?)
Any ideas for implementing multi-GPU support? Would splitting the domain across GPUs work?

Also, I’m trying to implement an immersed boundary method by adapting the existing Particle code. It has seemed to work.

Thanks in advance!

Jason
