Abstract

The present invention discloses a computing apparatus, including: at least one general computing core circuit, an internal interface circuit, an external interface circuit, a cache coherence engine circuit, and a protocol conversion circuit. The computing apparatus is coupled to an internal apparatus by using the internal interface circuit, and is coupled to an external apparatus by using the external interface circuit. When working in a first mode, the cache coherence engine circuit implements cache coherence between the computing apparatus, the internal apparatus, and the external apparatus, and in this case, the computing apparatus is used as a node controller. When working in a second mode, the cache coherence engine circuit processes only cache coherence between the apparatus and the internal apparatus, and the external interface circuit is used as a network interface circuit. The present invention further discloses a node device and a server. By means of the foregoing manner, in the present invention, different working modes of the computing apparatus can be configured, so that different types of servers may be constituted by using apparatuses of a same type, thereby implementing flexible switching between different solutions.

Description

technical field [0001] The present invention relates to the computing field, in particular to a computing device, a node device and a server. Background technique [0002] The server is composed of CPU (central processing unit), memory and peripherals. To improve the computing performance of the server, you can use the Scale-up (vertical expansion) or Scale-out (horizontal expansion) method to build the server. [0003] A large scale-up server uses multiple CPUs to form a multi-channel server. Several CPUs are interconnected through the system bus and share memory and peripherals to form a node; nodes are connected through dedicated chips such as node controllers. , and enable the CPU in the node to access the memory and peripherals of other nodes, and the node controller mainly handles the cache coherence between the CPUs. The cost of multi-channel servers is relatively high, but the calculation speed is very fast, which is suitable for occasions that need to respond quick...
