All notable changes to SimAI are documented in this file.
- SimCCL v2.30 mock: NCCL-style collective flow decomposition with Ring, PAT, and NVLS algorithm support.
- Protocol-aware selection (LL/LL128/Simple based on message size).
- SimCCL standalone binary for independent collective operation analysis (no GPU required).
- Per-(algorithm, protocol, link_type) send latency table for higher simulation fidelity.
- GPU memory modeling for inference simulation (parameter counting & KV cache).
- Linear interpolation for decode time estimation (replacing nearest-neighbor).
- Prefill-Decode Disaggregation memory planning (independent budgets for Prefill/Decode).
- End-to-end simulation for multi-request inference workloads.
- Advanced Inference Simulation: Model complex scenarios with Prefill/Decode separation.
- Modern Model Support: DeepSeek, Qwen3Moe and Qwen3Next.
- Request Scheduling: Adapted from Microsoft's Vidur.
