通俗地讲,集群是指一组计算机以某种方式联结起来并协同完成特定任务的系统。在这个系统中,计算机可以是同构的(如目前最常使用的基于x86构架的PC服务器),也可以是不同构的(如混合采用PC服务器及RISC服务器),而系统内各计算机之间可采用以太网或专用网络连接。使用集群技术的系统具有以下几个方面的优点:高可扩展性:采用集群技术的系统的性能随着CPU个数的增加几乎是线性变化的。另外系统扩展的时 To put it in a nutshell, cluster refers to a system of computers that are somehow tied together and collaboratively accomplish specific tasks. In this system, the computers can be isomorphic (such as the most commonly used x86-based PC servers) or heterogeneous (such as a mixture of PC servers and RISC servers), and the computers in the system Can use Ethernet or private network connection. Systems using clustering technology have the following advantages: High scalability: The performance of systems with clustering technology varies almost linearly with the number of CPUs.
