Top 9 C++ mlir Projects

ncnn

1 19,125 9.4 C++

ncnn is a high-performance neural network inference framework optimized for the mobile platform

Project mention: AMD Funded a Drop-In CUDA Implementation Built on ROCm: It's Open-Source | news.ycombinator.com | 2024-02-12

ncnn uses Vulkan for GPU acceleration, I've seen it used in a few projects to get AMD hardware support.

iree

6 2,363 10.0 C++

A retargetable MLIR-based machine learning compiler and runtime toolkit.

Project mention: Calyx, a Compiler Infrastructure for Accelerator Generators | news.ycombinator.com | 2024-03-04

How is this different than the mlir infrastructure of llvm and xla implemented in https://iree.dev/?
WorkOS

Circuit IR Compilers and Tools
torch-mlir

1 1,156 9.8 C++

The Torch-MLIR project aims to provide first class support from the PyTorch ecosystem to the MLIR ecosystem.

Project mention: Pytorch with AMD Radeon RX 6950 XT GPU: Is it possible on Windows 11? | /r/pytorch | 2023-05-13

You're best option is to use torchmlir : https://github.com/llvm/torch-mlir
concrete

1 1,097 9.7 C++

Concrete: TFHE Compiler that converts python programs into FHE equivalent

Project mention: Concrete: Converts Python programs into homomorphic encryption equivalent | news.ycombinator.com | 2024-03-09
vast

1 334 9.9 C++

VAST is an experimental compiler pipeline designed for program analysis of C and C++. It provides a tower of IRs as MLIR dialects to choose the best fit representations for a program analysis or further program abstraction.

Project mention: Print(“lol”) doubled the speed of my Go function | news.ycombinator.com | 2023-08-23

Most languages target C or LLVM, and C and LLVM have a fundamentally lossy compilation processes.
To get around this, you'd need a hodge podge of pre compiler directives, or take a completely different approach.
I found a cool project that uses a "Tower of IRs" that can restablish source to binary provenance, which, seems to me, to be on the right track:
https://github.com/trailofbits/vast
I'd definitely like to see the compilation processes be more transparent and easy to work with.
Pylir

0 126 9.2 C++

An optimizing ahead-of-time Python Compiler
InfluxDB

Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
LLVM-Guide

0 104 4.7 C++

LLVM (Low Level Virtual Machine) Guide. Learn all about the compiler infrastructure, which is designed for compile-time, link-time, run-time, and "idle-time" optimization of programs. Originally implemented for C/C++ , though, has a variety of front-ends, including Java, Python, etc.
