Performance Optimisation of Domestic Processors and Automated Migration Platforms

In this sharing, we discuss in-depth the adaptation and optimisation of domestic processors, focusing on how to accelerate the adaptation and performance optimisation of cloud products in Xinchuang scenarios through an automatic migration platform. In the sharing, we first introduced the mainstream instruction architecture and microarchitecture of domestic processors, including the characteristics and performance comparison of Haikuang, Feiteng and Kunpeng processors. Then, through specific cases, we explain in detail the common problems encountered in the adaptation process and their solutions, especially the debugging of compilation errors and the location of runtime errors. In the performance optimisation section, we focus on the characteristics of ARM V8 processor and introduce how to improve program performance through code layout optimisation, compiler optimisation, instruction set optimisation and memory model optimisation. In particular, significant performance improvements are achieved through the application of high-performance libraries and instruction sets, such as vectorised instructions and atomic operation instructions. Finally, the presentation introduced the Cintron Migration Platform, which is based on static detection and dynamic analysis of the compiler, and is capable of automatically completing code adaptation and optimisation. Through the one-stop performance analysis platform, users can quickly and efficiently complete the CCTF migration work, and at the same time obtain the double guarantee of technical growth and project success. The aim of this sharing is to help R&D staff better understand and apply the characteristics of domestic processors, and accelerate the adaptation and optimisation of cloud products in CCTV scenarios through systematic, tool-based and automated approaches.
