Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0020] A computer system provided by the first embodiment of the present invention includes several nodes that communicate with each other, each node is a data processing module and includes several CPUs (central processing units), several storage units connected to the CPUs in one-to-one correspondence, a first A node controller and a second node controller. The nodes are connected to each other in a certain way, for example, the nodes are connected in a quadrilateral, prism and other arrangements. The...

Abstract

The invention discloses a computer system, which comprises m groups, wherein each group comprises n nodes; m is a natural number more than or equal to 1; n is a natural number more than or equal to 2; each node comprises a first node controller and a second node controller; the nodes are directly or indirectly connected through the first node controller and the second node controller to realize information interconnection; and for the directly connected nodes, the first controller of any node is correspondingly connected with the first controllers of other nodes, and a second controller of any node is correspondingly connected with the second controllers of the other nodes so as to form a double interconnected architecture among the nodes. The connected nodes of the computer system are directly interconnected through the node controllers without extra interconnection module, so that information interconnection across nodes can be finished. Therefore, the usage of interconnecting chipscan be reduced, the cross-node access path can be shortened, the access delay time can be reduced, the cost can be reduced and the system performance can be improved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a computer system. Background technique [0002] Judging from the current architecture of some small computer systems (such as commercial servers), they can be roughly divided into three categories, namely, SMP (Symmetric Multi-Processor: Symmetrical Multi-Processor Structure), MPP (MassiveParallel Processing: Massive Parallel Processing Structure) and NUMA (Non-Uniform MemoryAccess: non-uniform memory access structure). [0003] The so-called SMP refers to the symmetrical work of multiple CPUs (central processing units) in the server, without primary and secondary or subordination. Each CPU shares the same physical memory, and the time required for each CPU to access any address in the memory is the same, so SMP is also called a uniform memory access structure (UMA: UniformMemory Access). The main feature of the SMP server is sharing, and all resources (CPU, memory, I / O, etc.)...
