Microsoft is once again pushing the boundaries of artificial intelligence with its latest innovation: a quartet of AI compilers named Rammer, Roller, Welder, and Grinder.

Developed in collaboration with esteemed academic institutions, these compilers promise to revolutionize the performance optimization of AI models.

In essence, compilation is the process of translating human-readable source code into machine code that computers can understand.

Microsoft’s new compilers are designed to streamline this process for mainstream AI models, making them run more efficiently on hardware accelerators like GPUs.

The recent blog post by Microsoft Research emphasizes the significant advancements these compilers bring to the world of AI.

According to Jilong Xue, Principal Researcher at MSR Asia, “The AI compilers we developed have demonstrated a substantial improvement in AI compilation efficiency, thereby facilitating the training and deployment of AI models.” Xue also hinted at the possibility that these compilers could play a role in future AI model optimization.

Each of these four compilers addresses specific challenges in optimizing AI workloads:

Rammer: Maximizes hardware parallelism by minimizing runtime scheduling overhead and enhancing performance by efficiently utilizing parallel resources.

Roller: Uses a fast construction algorithm to accelerate compilation, generating optimized kernels in seconds, reducing design time significantly.

Welder: Tackles memory access bottlenecks by reducing memory access traffic through a streamlined pipeline of connected operators, improving memory optimization efficiency.

Grinder: Optimizes control-flow execution on accelerators by integrating it with data flow, improving overall efficiency.

These compilers have been rigorously tested and have outperformed existing solutions in various benchmarks.

Rammer demonstrated up to a 20x performance improvement on GPUs.

Roller-matched or exceeded state-of-the-art performance while drastically reducing compilation times.

Welder outperformed frameworks like PyTorch by up to 21x on GPUs.

Grinder accelerated models with control flow by up to 8x.

Microsoft’s commitment to AI innovation, as seen through collaborations with research giants like OpenAI, is evident.
