Microsoft unveils ‘Heavy Metal Quartet’ of AI compilers to boost performance

• Microsoft introduces four new AI compilers: Rammer, Roller, Welder, and Grinder.
• These compilers showcase Microsoft’s continued leadership in designing groundbreaking AI systems.
• They also make AI models run more efficiently on hardware accelerators such as GPUs.

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

These cutting-edge compilation tools have been developed in collaboration with esteemed academic institutions, and they promise to revolutionize the performance optimization of AI models.

Compilation, in essence, is the process of translating human-readable source code into the machine code that computers understand—a series of ones and zeros.

Microsoft’s new compilers are engineered to streamline this transformation for mainstream AI models, making them run more efficiently on hardware accelerators such as GPUs.

In a recent blog post by Microsoft Research, the company emphasized the significant advancements these compilers bring to the world of AI.

Jilong Xue, Principal Researcher at MSR Asia, stated, “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 large-scale AI models could themselves assist in optimization and compilation in the future.

Each of the four compilers tackles specific challenges in optimizing AI workloads:

1. Rammer: Rammer’s primary focus is on maximizing hardware parallelism, a crucial factor in performance. It achieves this by minimizing runtime scheduling overhead through the improved utilization of parallel resources.
2. Roller: Roller takes a different approach, using a fast construction algorithm to accelerate compilation. This results in the generation of optimized kernels in mere seconds, a significant reduction compared to the hours it might take otherwise. Roller simplifies the design process, helping create efficient AI programs faster.
3. Welder: Memory access can be a significant bottleneck in AI workloads. Welder addresses this issue by reducing expensive memory access traffic through a concentrated pipeline of connected operators. It streamlines memory optimizations into a single framework for greater efficiency.
4. Grinder: Grinder tackles the challenge of control-flow execution on accelerators by integrating it with data flow. This innovative approach enables optimization across control flow boundaries, much like an expert guiding an apprentice to perform tasks more efficiently.

Microsoft’s commitment to AI innovation is well-established. The company has been at the forefront of AI advancement, collaborating with research giants like OpenAI to develop cutting-edge language models such as GPT-3.5 and GPT-4.

Recently, Microsoft joined forces with Meta to integrate LLaMA-2 into its cloud computing solutions and introduced the Algorithm of Thoughts to enhance reasoning in models like ChatGPT.

Testing of these new compilers has yielded remarkable results, with each outperforming existing solutions on benchmarks:

• Rammer demonstrated a performance improvement of up to 20x on GPUs compared to other compilers.
• Roller-matched or exceeded state-of-the-art performance while drastically reducing compilation times.
• Welder surpassed frameworks like PyTorch by up to 21x on GPUs.
• Grinder accelerated models with control flow by up to 8x.

Microsoft’s “heavy metal quartet” of AI compilers showcases the company’s continued leadership in designing groundbreaking AI systems. While high-profile partnerships, such as the one with OpenAI, often dominate headlines, Microsoft’s relentless pursuit of AI infrastructure development behind the scenes is equally crucial.

With these substantial performance gains over existing solutions, Rammer, Roller, Welder, and Grinder are poised to provide significant competitive advantages as the demand for complex AI workloads continues to grow.

Microsoft’s commitment to pushing the boundaries of AI technology remains unwavering, and these compilers are just one more testament to their dedication to innovation in the field.
