Node partition dividing method, device and server

Abstract

The embodiment of the invention discloses a node partition dividing method, device and server, relating to the field of electronic information technology. Through the invention, a partition scheme with a minimum hop count of QPI (quick path interconnect) can be automatically analyzed and obtained according the topological structure of the system, thus the influence of subjective factors is avoided in manual partition division, and the reduction of the operation speed caused by improper partition is relieved so as to relieve the reduction of system performance. The method comprises the following steps of: obtaining the topological structure of the system and the number of nodes participating in partition, wherein the system comprises at least three nodes, and each node comprises at least two CPUs (central processing units); determining the connection information according to the topological structure of the system, wherein the connection information includes the connection relationship between each CPU and other CPUs in the system; and determining the partition scheme according to the number of nodes participating in partition and the connection information, wherein the number of nodes in the partition scheme is the number of nodes participating in partition. The method, device and server disclosed by the invention are applicable to server partition.

Description

technical field [0001] The present invention relates to the field of electronic information technology, in particular to a method, device and server for dividing node partitions. Background technique [0002] With the development of electronic information technology, the amount of data in various electronic information systems is increasing. For example, in order to support 3G networks, wireless communication systems must carry greater data traffic; online storage systems in the Internet must support more More users need to expand the data capacity of the system. All kinds of electronic information systems have higher and higher requirements for data carrying capacity and fault tolerance performance. [0003] As a result, the server interconnection technology was derived, that is, through QPI (QuickPath Interconnect, fast interconnection channel) and other technical means to connect the CPUs in multiple nodes to each other, so that multiple nodes that originally worked inde...

Problems solved by technology

As a result, the access delay of the CPU is caused, and the CPU needs to spend extra time in the operation process to wait for the data transmitted by other CPUs other than the QPI that is separated by many hops, thereby reducing the operation rate of the entire partition.

[0005] In the existing technology, the main reason for the above problems is that the process of dividing node partitions and interconnecting CPUs is manually completed by technicians, and in order to ensure that the partitions can have a higher computing speed, technicians need to collect system information. Monitor the data and analyze the optimal partition scheme based on your own experience and knowledge, which will inevitably increase the workload of the staff

For some systems with unstable operation conditions, it is necessary to modify the partition frequently, which requires technicians to manually monitor the operation of the system continuously and manually modify the partition at any time, which requires a lot of time and workload for the technicians, and increases the system running cost
