Abstract: High performance computing (HPC) has entered the post exascale era. As the core components of supercomputers, high performance processors provide super computing power for HPCS through the core computing architecture. The research progress of core computing architecture represents the development direction of high performance processor architecture. Aiming at advanced high performance processors for exascale computing, this paper analyzes and discusses the research progress of core computing architecture from the aspects of computing resource organization structure, data and instruction level parallelism, domain-specific acceleration structure, data type and computing power, and predicts the development trend of the core computing architecture for high performance processors. The main research and development directions of the core computing architecture of future high  performance processors are ultra-wide vector SIMD and SIMT, domain-specific architecture for matrix computation accelerate, and support of various low precision computation for HPC and AI fusion.

Key words: high performance computing, exascale computing, computing architecture
