Author of the rpcx microservice framework, original book author, and chair of Baidu's Go CMC committee.
This article walks through the mathematics of Bloom filters, showing how to model false‑positive probability, derive optimal bit array size and hash‑function count, and apply the formulas to a 4‑million‑item dataset with concrete examples and performance tables.
The article analyses a large‑scale benchmark comparing Go, C, Rust, C# and other languages under single, 100 k and 1 M concurrent tasks, revealing how Go’s 64‑bit int array size and goroutine stack overhead cause dramatically higher memory consumption despite comparable CPU performance.
This tutorial walks through the complete RDMA programming workflow using the ibverbs API, covering device initialization, memory registration, completion queue and queue pair creation, state transitions, send/receive operations, completion handling, and resource cleanup with concrete C code examples.
Establishing an RDMA connection requires exchanging key parameters such as LID, QP number, and memory keys, and this article systematically outlines the essential information, compares six exchange methods—from static configuration to distributed services—and evaluates their advantages, drawbacks, and suitable scenarios.
Ben Dicken benchmarked a double‑nested loop of 10 000 × 100 000 iterations across dozens of languages, publishing the source code and fastest‑run results that show C, Zig and Rust consistently topping the performance chart, illustrated with an animated speed comparison.
The article explains hash algorithm fundamentals, compares common hashes, presents extensive Go benchmark results across multiple data sizes, highlights the superior performance of Go's maphash (memhash) implementation, and shows how to access it via linkname and assembly details.
This guide walks you through the hardware requirements, cost considerations, and step‑by‑step configuration of a simulated RDMA network using Soft‑RoCE on both Red Hat/CentOS and Ubuntu, including verification with ibv tools and performance testing.
This article explains the fundamentals of RDMA, compares libibverbs and rdma_cm with the user‑space rsocket API, and walks through a complete Go implementation using the smallnest/rsocket library, including both server and client code examples and practical deployment tips.
The article provides a detailed, step‑by‑step tour of xAI’s Colossus supercomputer— a $‑billion AI cluster built in 122 days with 100,000 NVIDIA H100 GPUs—covering Supermicro liquid‑cooled 4U racks, cooling distribution units, power and water infrastructure, storage nodes, CPU servers, 400 GbE networking, and the operational challenges of scaling such a massive system.
This article walks through the full process of delivering high‑quality 4K video at minimal cost by comparing storage providers, choosing Cloudflare R2 for its free outbound bandwidth, encoding with FFmpeg, packaging with HLS, uploading via rclone, and playing back with HLS.js or a custom web component.
