摘　　要：This article presents a comprehensive performance evaluation of Phytium 2000+,an ARMv8-based 64-core architecture.We focus on the cache and memory subsystems,analyzing the characteristics that impact the high-performance computing applications.We provide insights into the memory-relevant performance behaviours of the Phytium 2000+system through micro-benchmarking.With the help of the well-known roofline model,we analyze the Phytium 2000+system,taking both memory accesses and computations into account.Based on the knowledge gained from these micro-benchmarks,we evaluate two applications and use them to assess the capabilities of the Phytium 2000+system.The results show that the ARMv8-based many-core system is capable of delivering high performance for a wide range of scientific kernels.
