## Experimental WIP: Multi turn with/without CPU KVCache Offloading

lit review
- https://lmsys.org/blog/2025-09-10-sglang-hicache/
- sglang calls GPU HBM as (L1) and CPU DRAM as (L2)
- https://lmsys.org/images/blog/hicache/mooncake_benchmark.png
- single turn long context Q&A https://arxiv.org/abs/2311.04939 (seems more like an shared prefix style similar to cascade attention (pre cursor to sglang radix attention )) https://flashinfer.ai/2024/02/02/cascade-inference.html
- Production Alibiba Multi turn dataset https://arxiv.org/abs/2506.02634 (seem to not provide the acutal prompts and outputs tho, more just prompt lengths and output lengths, etc.)
- sglang synthetic multi turn benchmark script here https://github.com/sgl-project/sglang/tree/main/benchmark/hicache
- interestingly sglang blog simulates PD disagg via just setting OSL as 1
```bash
python3 benchmark/hicache/bench_multiturn.py --model-path $MODEL_PATH --disable-random-sample \
--output-length 1 --request-length 2048 \ # simulate P-D disaggregation
```
