| Abstract (English): | The technological evolution of high-performance computing (HPC) has always been closely intertwined with the strategic demands in fields such as national defense and military affairs, fundamental science, and industrial engineering. Its development can be broadly divided into 4 key stages: dedicated vector machine, massively parallel computer, heterogeneous parallel computer, and HPC-AI converged computer. Each stage continuously advances in system architecture, software ecosystems, and application paradigms. Currently, HPC is undergoing a profound paradigm shift driven by artificial intelligence." AI for Science" has emerged as a new scientific research paradigm, in which the high-performance with high-precision for scientific computing and high-performance with mixed-precision characteristics for intelligent computing are converging deeply. This convergence poses formidable challenges to underlying computing architectures in terms of precision coordination, data exchange, and I/O pattern adapta-tion. Looking ahead to the development of HPC-AI converged HPC technologies, the competitive focus is shifting from single floating-point peak performance toward a comprehensive consideration of data movement efficiency, energy-performance ratio, and system scalability. Tighter integration among computing units, more efficient data flow, and more unified programming abstractions will become crucial features of next-generation HPC systems. The CPU-SIMT converged computing architecture, as a promising HPC-AI converged computing architecture, employs a solution combining "converged computing architecture+ hierarchical interconnection networks+converged parallel storage". This solution is expected to break through the "communication wall" bottleneck in tightly coupled HPC-AI converged computing applications, offering a new technological pathway for building next-generation HPC systems and efficiently supporting applications under the emerging "AI for Science" computing paradigm.
