Original link: https://hsiaofongw.notion.site/a6fd2feb9a7445b2a1657a8c90ad9258 This paper introduces the implementation method of multi-core parallel computing, and compares the effects of pipeline parallelism and data parallelism. The key to realizing pipeline parallelism is to use barrier synchronization mechanism to realize synchronization between workers and pipeline conveyor belt. In a more complex system, it may be necessary to explicitly
