A technical paper titled “WWW: What, When, Where to Compute-in-Memory” was published by researchers at Purdue University.

Abstract:

“Compute-in-memory (CiM) has emerged as a compelling solution to alleviate high data movement costs in von Neumann machines. CiM can perform massively parallel general matrix multiplication (GEMM) operations in memory, the dominant computation in Machine Learning (ML) inference. However, re-purposing memory for compute poses key questions on 1) What type of CiM to use: Given a multitude of analog and digital CiMs, determining their suitability from systems perspective is needed. 2) When to use CiM: ML inference includes workloads with a variety of memory and compute requirements, making it difficult to identify when CiM is more beneficial than standard processing cores. 3) Where to integrate CiM: Each memory level has different bandwidth and capacity, that affects the data movement and locality benefits of CiM integration.
In this paper, we explore answers to these questions regarding CiM integration for ML inference acceleration. We use Timeloop-Accelergy for early system-level evaluation of CiM prototypes, including both analog and digital primitives. We integrate CiM into different cache memory levels in an Nvidia A100-like baseline architecture and tailor the dataflow for various ML workloads. Our experiments show CiM architectures improve energy efficiency, achieving up to 0.12x lower energy than the established baseline with INT-8 precision, and upto 4x performance gains with weight interleaving and duplication. The proposed work provides insights into what type of CiM to use, and when and where to optimally integrate it in the cache hierarchy for GEMM acceleration.”
