GPU resource requirement and compatibility with NVILA

Hi,
Thanks a lot for sharing this wonderful work. 
I had mainly two questions,
1. What is the resource requirements for each stage of SpatialRGPT? Does it require 16 nodes as specified in the supplementary or where any modifications done later on to run it on even lesser number of GPUs?
2. Will the intermediate models say for after stage1 and stage2 be provided?

Thank you in advance.
