Weekly Paper Notes — one of the top picks from the 2026-06-20 CS paper digest. Area: Distributed Computing. Authors: Jiasheng Zhou, Longbin Zeng, Clavis Chen, Ruiming Lu et al. arXiv: 2606.20374 · PDF TL;DR ARGUS is a tracing and performance-diagnosis system designed for always-on operation on production LLM training clusters with more than 10,000 GPUs. The central insight is that no single profiler can be cheap, deep, and continuous all at once — so ARGUS decomposes observation along the training call hierarchy into three independent collection channels: CPU call stacks, framework semantics, and GPU kernel execution....

Weekly Paper Notes — one of the top picks from the 2026-06-20 CS paper digest. Area: Databases / Systems. Authors: Georg Kreuzmayr (TigerBeetle), Muhammad El-Hindi (TUM), Benjamin Wagner (Firebolt), Tobias Ziegler (TigerBeetle), Viktor Leis (TUM) arXiv: 2606.19969 · PDF TL;DR For two decades distributed database systems treated the network as an opaque, kernel-managed pipe and the kernel TCP stack was fast enough that this abstraction was free. It isn’t anymore....

Seminal Paper of the Week — the paper that quietly defined what “cloud storage” looks like from the inside. Authors: Sanjay Ghemawat, Howard Gobioff, Shun-Tak Leung (Google) Published: SOSP ‘03 — 19th ACM Symposium on Operating Systems Principles, October 2003. Canonical link: The Google File System (Google research mirror) · ACM DOI 10.1145/945445.945450 TL;DR In 2003, Ghemawat, Gobioff and Leung described how Google was running a multi-thousand-node, petabyte-scale distributed file system on commodity hardware — and how the design assumptions diverged so sharply from the established POSIX-file-system lineage that almost every architectural decision in the paper looks like a heresy until you read the workload section....
