Early Performance Evaluation of Dawning 5000A and DeepComp 7000

In this paper, we present our early performance evaluation results with the NPB benchmark and two scientific computing applications program, i.e., a HFFT package developed by our lab and a CFDO application software, on two 100 Teraflops-scale Dawning 5000A and DeepComp 7000. We compared the NPB performance evaluation results of Dawning 5000A and DeepComp 7000, with their corresponding predecessor, Dawning 4000A and DeepComp 6800, which demonstrating their performance improvements across a variety of NPB benchmark problems. From our evaluation results, we can find that the NPB benchmark can keep its scalability up to 16384 cores on Dawning 5000A while on DeepComp 7000 this number becomes 4096. We also find that the HFFT scales well over 2048 cores while the CFDO scales well over 512 cores on Dawning 5000A.
