Description

technical field [0001] The invention relates to the technical field of computer architecture, in particular to a configurable multi-processor computer system and its implementation method. Background technique [0002] High-performance computing has become an important auxiliary means in the fields of basic scientific research, national economic development, and national defense science and technology construction. Its popularization and application in various industries is changing the traditional research and development model of the industry, and it is also reversely promoting popular high-performance computers. development of. Therefore, the development of high-performance computer systems can be divided into two directions, one is scalable computer systems for exascale applications; the other is high-efficiency special-purpose computer systems customized for application requirements. [0003] At present, although the computing power of general-purpose processors contin...

Problems solved by technology

There are two deficiencies in the multi-processor computer system with the above structure: on the one hand, the computing acceleration components are tightly coupled with the general-purpose processor, and the utilization rate of the components is not high. If other general-purpose processors in the system need to use the computing acceleration components, the data must be Passed to the general-purpose processor connected to the acceleration component, and then forwarded to the calculation acceleration component, which will bring additional communication overhead and reduce system performance; on the other hand, whether it is Infiniband, Ethernet or other high-performance networks, there are Additional network protocol overhead. When the computing unit processes these network protocols, a certain amount of protocol processing time is required, which increases communication delays and reduces the performance of the entire multiprocessor computer system.
