GPU Cuckoo Filter – faster queries than Blocked Bloom, with deletion

In plain words

GPU Cuckoo Filter is a data structure tool designed for users who need fast membership queries with the ability to delete entries. It runs on GPUs and offers faster query performance compared to Blocked Bloom filters while supporting item removal, a feature Bloom filters lack. The tool is available as open-source code on GitHub and targets developers working with large datasets who require both speed and deletion capabilities.

From the sources

A high-performance, lock-free CUDA implementation of the Cuckoo Filter. This library is the companion code for the paper "Cuckoo-GPU: Accelerating Cuckoo Filters on Modern GPUs" . This library provides a GPU-accelerated Cuckoo Filter implementation optimized for high-throughput batch operations. Cuckoo Filters are space-efficient probabilistic data structures that support insertion, lookup, and deletion operations with a configurable false positive rate. Benchmarks at 95% load factor on an NVIDIA GH200 (H100 HBM3, 3.4 TB/s) with 16-bit fingerprints and equivalent space allocation for the Blocked Bloom Filter. The PCF runs on an Intel Xeon W9-3595X CPU (120from github.com

  The video demo runs a 7b Model on a normal gaming GPU. I think it already works quite well (accounting for the limited hardware power). :)

  BloomSearch – Keyword search with hierarchical Bloom filters2025 · github.com · ▲66

  Hey HN! I got nerd-sniped by Bloom Filters this weekend, specifically for searching datasets with high "cardinality" (number of unique items). They're an _amazing_ data structure that, at a fixed size, tracks potential set membership. That means unlike normal b-tree indexes, they don't grow with the number of unique items in the dataset. This makes them great for "needle in a haystack" search (logs, document) as implementations like VictoriaMetrics and Bing's BitFunnel show. I've used them in the past, but they've never been center-stage in my projects. I wanted high cardinality keyword…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
