How DiffusionGemma Shifts LLM Inference Bottleneck from Memory Bandwidth to Compute

DiffusionGemma, an experimental discrete text diffusion model built on the 26B MoE Gemma‑4 architecture, generates whole 256‑token blocks with bidirectional attention, moving the inference bottleneck from memory bandwidth to GPU compute, achieving up to four‑fold speed gains on H100 and RTX 5090 GPUs, though with lower output quality than standard autoregressive models.

Flash-KMeans: Fast, Memory-Efficient Exact K-Means for Billion-Scale Clustering on a Single GPU

Flash‑KMeans is a newly proposed framework that re‑designs exact K‑Means for GPUs by eliminating distance‑matrix materialization, using FlashAssign’s online argmin and Sort‑Inverse Update to cut memory bandwidth and atomic‑write contention, achieving up to 12.5× speedup and dramatically lower VRAM usage on billion‑point datasets.
