About

FlagGems is part of FlagOS, a fully open-source system software stack designed to unify the model–system–chip layers and foster an open and collaborative ecosystem. It enables a "develop once, run anywhere" workflow across diverse AI accelerators, unlocking hardware performance, eliminating fragmentation among AI chipset-specific software stacks, and substantially lowering the cost of porting and maintaining AI workloads.

FlagGems is a high-performance, generic operator library implemented in Triton language. It is built on a collection of backend-neutral kernels that aims to accelerate LLM (Large-Language Models) training and inference across diverse hardware platforms.

By registering with the ATen backend of PyTorch, FlagGems facilitates a seamless transition, allowing model developers to switch to Triton without changing the low level APIs. Users can continue using their familiar Pytorch APIs while at the same time benefit from new hardware acceleration technologies. For kernel developers, the Triton language offers readability, user-friendliness and performance comparable to CUDA. This convenience allows developers to engage in the development of FlagGems with minimal learning investment.

Features

FlagGems provides the following technical features.

• A large collection of PyTorch compatible operators
• Hand-optimized performance for selective operators
• Eager-mode ready, independent of torch.compile
• Automatic pointwise operator codegen supporting arbitrary input types and layout
• Fast per-function runtime kernel dispatching
• Multi-backend interface enabling support of diverse hardware platforms
• Over 10 supported backends
• C++ Triton function dispatcher (working in progress)

Check the features documentation for more details.
