Abstract

The invention discloses a cluster node communication method. The cluster node communication method comprises the following steps: a first master node obtains data of slave nodes in a first cluster and caches the data; the first master node is located in the first cluster; the first master node receives a call request of data of the slave nodes in the first cluster sent by a second master node, wherein the second master node is located in a second cluster; and the first master node caches to-be-called data requested by the second master node obtained from the cache and returns the to-be-called data to the second master node. According to the cluster node communication method, the master node caches the data of the slave nodes in the cluster, therefore the master nodes in other clusters can access the master node to obtain the data of the slave nodes in the cluster, therefore the direct communication between the slave nodes and the master nodes in other clusters can be avoided, and thus the reduction of system request response speed caused by the fault of the slave nodes can be avoided. The invention further discloses a cluster node communication system, which has the same beneficial effects.

Description

technical field [0001] The present application relates to the field of cluster technology, in particular to a cluster node communication method and system. Background technique [0002] With the rapid development of computer system technology, the hardware equipment used in high-performance computing has experienced the transition from vector computer to parallel computer and then to cluster system. Nowadays, cluster systems (hereinafter referred to as clusters) have been more and more widely used in high-performance computing. [0003] A cluster refers to a group of service entities such as computers that are independent of each other and interconnected through a high-speed network, and they provide services to the outside world as a single system. Each service entity in the cluster is a node, and in a cluster, there is generally one master node, and the rest are slave nodes. The slave nodes can store data; the master node can communicate with each slave node, and then ca...
