No, We Don't Have to Choose Batch Sizes As Powers Of 2

Read Original

This technical article critically analyzes the deep learning convention of setting batch sizes to powers of 2 (e.g., 64, 128). It explores the theoretical justifications, such as memory alignment and GPU efficiency for matrix operations, and discusses whether this practice is always necessary or beneficial in practical training scenarios.
