Wpf is a framework for building entire classes of applications that have previously been difficult or impossible to write in j2ee - applications that require high availability , high transaction rates , very large in - memory caches , and likely partitioned databases ( wpf )是用于构建整个应用程序类的框架。之前将这些应用程序写入j2ee是很困难甚至是无法实现的这些应用程序需要高可用性、高事务处理速率、高速缓存以及合适的数据库划分。
The premise to assure qos is to provide sufficient resource to meet demands . we come up with a method to partition the resources of web cluster for each class with its resource demand and priority requirement taken for granted , where system processing time or average access rates is summed up for each class periodically and resource demands is evaluated with stretch factor as performance metric . also the nodes marked in number will be orderly assigned to the classes ordered in priorities , which helps to maintain data locality and improves memory cache hits 资源满足需求是实现服务质量保证的前提,为满足业务类动态的资源需求,我们提出一种支持业务类优先级和资源需求的资源划分方法,通过按周期对业务类请求处理时间或平均访问率进行统计,以响应扩展因子为质量指标对业务类预期的资源需求作出评估,采取按主机编号有序地分配给按优先级排序的业务类,减少业务类资源变动和提高主存cache命中率。
(computer science) RAM memory that is set aside as a specialized buffer storage that is continually updated; used to optimize data transfers between system elements with different characteristics 同义词:cache,
