AIBench Training: Balanced Industry-Standard AI Training Benchmarking

Earlier-stage evaluations of a new AI architecture/system need affordable AI benchmarks, while using a few AI component benchmarks alone in the other stages may lead to misleading conclusions. This paper proposes a balanced benchmarking methodology. Performing an exhaustive survey on Internet service AI domains, we identify and implement seventeen representative AI tasks with the state-of-the-art models to guarantee the diversity and representativeness of the benchmarks. Meanwhile, we keep a benchmark subset to a minimum for affordability. We contribute by far the most comprehensive AI training benchmark suite with seventeen industry partners. The evaluations show: (1) AIBench Training outperforms MLPerf Training in terms of the diversity and representativeness of model complexity, computational cost, convergent rate, computation and memory access patterns, and hotspot functions; (2) With respect to the AIBench full benchmarks, its subset shortens the benchmarking cost by 54%, while maintaining the primary workload characteristics; (3) The performance ranking shows the single-purpose AI accelerator like TPU with the optimized TensorFlow framework performs better than that of GPUs while losing the latters’ general support for a variety of AI models.
