Computation Is Fast, Use Threadlet!: Efficient Threading for μs-Scale Computing via OS/Hardware Co-Design

The conventional threading model multiplexes software threads onto hardware cores. This model inherently suffers from the overhead of 1) context switching, 2) scheduling, and 3) system event notifications (e.g., I/O interrupts). As computing enters μs-scale, such overheads become the key bottleneck of a wide range of d...

RedKnot: Efficient Long-Context LLM Serving with Head-Aware KV Reuse and SegPagedAttention

RedKnot establishes a new foundation for AI infrastructure by transforming the KV cache from a monolithic, passive runtime artifact into a dynamic, model-aware runtime substrate for scalable LLM serving.

Tessera: Unlocking Heterogeneous GPUs through Kernel-Granularity Disaggregation

Tessera is presented, the first kernel disaggregation system to improve performance and cost efficiency on heterogeneous GPUs for large model inference, and shows that a heterogeneous GPU pair under Tessera can even exceed the throughput of two homogeneous high-end GPUs at a lower cost.

GEB-Bench: Abstract Structures Told in Many Voices

Evaluating twelve open and proprietary models, it is found that abstraction failure is lawful, and the central finding is a gap between recognition and cross-voice mapping: models identify a structure within one voice far better than they carry it across voices; every model pays this tax, and mapping strong enough to n...

RedKnot-MLA: Multi-Head Offline-Online Reuse for DeepSeek-V4 Long-Context Serving

This work presents a DeepSeek-V4 realization of RedKnot's head-aware reuse principle, a DeepSeek-V4 realization of RedKnot's head-aware reuse principle, and describes the factorization, position repair, token-row closure, sparse-MoE support, TP8 integration, and the measurement boundaries needed to interpret these resu...

StrataCL: Fabric-Native Communication Library for Production Supernodes

StrataCL introduces registration-on-allocation to realize user-buffer direct communication, and designs communication operators with workload-balanced NPU-core partitioning and NPU-driven SDMA offloading to exploit supernode architecture features.
