Pull request overview
This PR adds SimAI 1.6 PD-separation (prefill/decode disaggregation) support for GPU memory simulation, expands model/device/node SKU configuration to cover additional large models and hardware, and checks in pre-generated AICB workload/HF config data.
Changes:
- Implement PD-aware cluster initialization and replica/world-size bookkeeping.
- Add new model configs (Qwen3-Next-80B, Qwen3-MoE-235B) and new device/node SKU configs (H20/H200/GB200).
- Add HF model config JSONs and AICB workload CSV/JSON artifacts; update
.gitignoreto keep required workload data tracked.
