Description
How does SimAI think about PP scheduling? And how to avoid PP during NCCL initialization?
NCCL initialization code：

Research direction
Start with the NCCL initialization references in astra-sim-alibabacloud/astra-sim/system/Sys.cc at lines 293 and 298, then trace how pipeline-parallel scheduling is represented around that entry point. A useful resolution would explain SimAI's PP scheduling model and document whether and how PP can be avoided during NCCL initialization.
