July 2026 monthly summary for vllm-ascend (vllm project). Focused on stabilizing MambaSpec KV cache with speculative decoding, delivering a critical bug fix that eliminates a block table overflow and enhances reliability for long-context, Mamba-based models in Ascend deployments. Implemented targeted code adjustments to align block allocation with runtime needs and validated through hands-on testing on Ascend NPU paths (Mamba + MTP).

Month: 2025-12 — Focus on performance optimization for rejection sampling in vllm-ascend. Features delivered include Triton-optimized kernels for rejection_greedy_sample_kernel and expand_kernel, integrated by refactoring rejection_sampler.py while preserving backward compatibility. Bugs fixed: no major user-facing bugs reported this month; stability maintained through backward-compatible changes. Impact: substantial throughput and latency improvements for rejection sampling across diverse batch sizes and MTP configurations, enabling higher GPU utilization and cost efficiency in large-model deployments. Technologies/skills demonstrated: Triton kernel development, Python refactoring, performance profiling, backward compatibility, and PR-driven collaboration (PR #4830; aligned with vLLM baseline v0.12.0).
