Slicing Is All You Need: Towards A Universal One-Sided Algorithm for Distributed Matrix Multiplication

This paper presents a novel universal one-sided algorithm for distributed matrix multiplication, supporting diverse partitionings and replication factors without requiring specific implementations for each variant. It leverages slicing (index arithmetic) for local matrix multiply operations, enabling efficient communication and computation overlap. The algorithm demonstrates competitive performance against state-of-the-art distributed tensor libraries like PyTorch DTensor on GPT-like model workloads.
