Tile-Level Activation Overlap for Efficient LLM Inference

arXiv:2607. 02521v1 Announce Type: cross Abstract: SwiGLU is the dominant MLP activation in modern large language models, yet its intermediate tensor materialization costs 9-37% of MLP execution time.

Scale-QLoRA: Code-Invariant Adapter Merging for Native 4-bit Microscaling LLMs

Scale-QLoRA introduces a method for merging LoRA adapters into native 4‑bit microscaling language models without altering the quantized code plane. By training only the per‑block scale field and freezing the E2M1 code, the merged model remains code‑invariant and can be deployed as a single checkpoint. Experiments on four models and tasks show that Scale‑QLoRA achieves accuracy‑lossless merging comparable to merge‑aware QAT‑LoRA, while offering benefits such as exact rollback, code‑plane deduplication, and a 125× faster scale‑only task swap.

GGUF-Metadata Prediction of Single-Sequence llama.cpp Throughput Across Three Systems

The paper predicts single‑sequence llama.cpp throughput from GGUF metadata using roofline‑shaped predictors with quantization‑specific scale factors. Experiments on 318 measurements across 53 host‑file configurations on two Apple M4 Max systems and an NVIDIA RTX 5080 show that an active‑parameter decode model achieves significantly lower mean absolute percentage errors compared to models that use total parameters. The study also finds that low‑bit model ladders alter runtime ordering and that GGUF structure improves predictions, though fitted efficiencies vary across systems.
