Summary:
For RecSys Inference when tables are offloaded onto SSD:
1. Specify and propagate the tables to be offloaded to SSD in TorchRec via FUSED_PARAMS as discussed with TroyGarden
2. Continue using torch.device("cpu") as compute device while using separate input / output dist for SSD (as in house SSD TBE kernel based on EmbeddingDB is different than CPU TBE kernel) by creating a new device group for SSD.
Would be renaming device_type_from_sharding_info to storage_device_type_from_sharding_info to clarify it better.
