awesome-simd

A curated list of awesome SIMD frameworks, libraries and software.

This list showcases projects that have achieved 10x performance improvements using SIMD (Single Instruction Multiple Data) instructions. In general this should lead to execution speeds of GBs per second on modern CPUs for that task at hand.

Parsing

• simdjson - C++: Parsing gigabytes of JSON per second
• simdjson-go - Go: Parsing gigabytes of JSON per second
• dictionary - C++: High-performance dictionary coding
• simdcomp - C: A simple library for compressing lists of integers using binary packing
• SIMDCompressionAndIntersection - C++: A library to compress and intersect sorted lists of integers using SIMD instructions
• Hyperscan - C++: High-performance regular expression matching library
• Various string algo's - C: Repository for string algorithms, snippets, toy programs, etc.
• sse-popcount - SIMD (SSE) population count

Erasure Coding and Hashing

• Reed-Solomon - Go: Erasure Coding in Go
• highwayhash - Go: Optimized HighwayHash implementation for Intel (over 10 GB/sec), ARM and Power9
• sha256-simd - Go: Optimized SHA256 computations for Intel, ARM and Power9

Neural Network

• ncnn - C++: High-performance NN inference framework optimized for mobile
• mkl-dnn - C++: Math Kernel Library for Deep Neural Networks
• nnpack - C/c++: Acceleration package for neural networks on multi-core CPUs

Image processing

• Simd - C++: image processing library making use of SIMD
• Pillow-SIMD - Python: SIMD version of PIL (Python Imaging Library)
• ComputeLibrary - C++: Library for Computer Vision and Machine Learning (ARM only)

Cool

• SIMD-Visualiser - Javascript: Graphically visualize SIMD code
• Visual ARM emulator - VisUAL: a highly visual ARM emulator
• faster - Rust: SIMD for humans
• Vectorized Emulation - Accelerated taint tracking at 2 trillion instructions per second
