Accera LLVM

Introduction

Accera is a programming model, a domain-specific programming language embedded in Python (eDSL), and an optimizing cross-compiler for compute-intensive code. Accera currently supports CPU and GPU targets and focuses on optimization of nested for-loops.

Writing highly optimized compute-intensive code in a traditional programming language is a difficult and time-consuming process. It requires special engineering skills, such as fluency in Assembly language and a deep understanding of computer architecture. Manually optimizing the simplest numerical algorithms already requires a significant engineering effort. Moreover, highly optimized numerical code is prone to bugs, is often hard to read and maintain, and needs to be reimplemented every time a new target architecture is introduced. Accera aims to solve these problems.

Accera has three goals:

• Performance: generate the fastest implementation of any compute-intensive algorithm.
• Readability: do so without sacrificing code readability and maintainability.
• Writability: a user-friendly programming model, designed for agility.

accera-llvm

The accera-llvm package contains pre-compiled custom LLVM binaries used to produce optimized code using the Accera eDSL. It is not designed for standalone use, but is automatically installed when you pip install accera. You can find documentation and examples on Github.

Supported platforms:

• Linux (manylinux) x64
• macOS x64
• Windows x64
