vector-api

A Java version of simdjson, a high-performance JSON parser utilizing SIMD instructions

Rendering library for Minecraft blocks, items, entities, fluids, and portals. Reads a vanilla client JAR and any stack of resource packs, then produces isometric or 2D previews as static PNGs or animated frame sequences.

High-performance math library using Java Vector API (requires JDK 26+)

Ultra-fast, SIMD-accelerated full-text search engine built on Java 22.

High-throughput systems. Zero-allocation patterns. Virtual thread mastery. Mechanical sympathy, custom JIT-friendly collections, lock-free concurrency. Project Loom, SIMD via Vector API, Aeron-style messaging. GraalVM native. No-frameworks. Standard Library + Unsafe. java -jar → Scale.

A high-performance in-memory vector database in Java with sun.misc.Unsafe off-heap storage and SIMD-accelerated math.

Ultra-low latency, Zero-GC engine for Nanopore "Read Until" adaptive sampling. Built with HFT principles, SIMD Vector API, and Project Panama.

A JVM benchmark lab: where explicit Vector-API SIMD earns its place in Parquet integer bit-unpacking, and where C2 already produces competitive scalar code (JDK 25, Vector API, MemorySegment).

Parallel gzip compression engine on JDK 25. Blocks are deflated on virtual threads and stitched into one gzip member that gzip and GZIPInputStream both accept. Includes a Vector API SIMD Adler-32 at 2.8x scalar Java, memory mapped I/O through the FFM API, JMH benchmarks, and a React landing page with an in browser compressor.
