Description
## Question
Great persentation at GTC.
Does Lightning Thunder work with DeepSpeed out of the box (assuming I didn't use FSDP) but used all other fusing, compilation options? Also how does FSDP interact with DeepSpeed?
* by DeepSpeed I specifically mean ZeRO 1, 2, 3, 2 + offload, and, 3 + offload
