The paper introduces the SOAP search space, encompassing Sample-Operation-Attribute-Parameter dimensions, for optimizing parallelization strategies in deep neural network training. The FlexFlow framework utilizes a guided randomized search algorithm with a novel execution simulator to efficiently explore the vast SOAP space and achieve significant speedups in DNN training.

The SOAP search space allows for flexible parallelization strategies across Sample, Operation, Attribute, and Parameter dimensions, outperforming traditional methods by up to 3.8 times. FlexFlow's simulator predicts performance without real executions, reducing search time and enhancing efficiency.
