Compiling LLMs into a MegaKernel: A path to low-latency inference

Researchers developed Mirage Persistent Kernel (MPK), a compiler that transforms LLM inference into a single GPU megakernel, fusing all operations and reducing latency by 1.2-6.7x. MPK optimizes execution by creating a task graph, efficiently scheduling tasks, enabling software pipelining, and overlapping computation with communication. It's especially effective for multi-GPU deployments and requires minimal code changes.
