Client-server architecture for multicore computer system to realize single-core-equivalent view

Abstract

A client-server architecture is used in a multicore computer system to realize a single-core-equivalent (SCE) view. In the system, plural stacks, each having a core and a local cache subsystem coupledthereto, are divided into a client stack for running client threads, and server stacks each for running server threads. A shared cache having shared cache blocks, each coupled to the client stack andto one or more server stacks, is also used. The core of an individual server stack is configured such that computing resources utilizable in executing the server thread(s) are confined to the individual server stack and the shared cache block coupled thereto, isolating an inter-core interference caused by the server thread(s) to the client thread(s) to within the individual server stack, the shared cache block coupled thereto, any server stack coupled to this shared cache block, and the client stack to thereby realize the SCE view. 在多核计算机系统中使用客户端‑服务器架构来实现单核等效(SCE)观感。在该系统中，多个栈被划分为一个客户端栈和服务器栈，该多个栈均具有一个核和耦合到该核的本地缓存子系统，该客户端栈用于运行客户端线程，该服务器栈均用于运行服务器线程。还使用具有共享缓存块的共享缓存，每个共享缓存块均耦合到客户端栈和一个或多个服务器栈。每个服务器栈的核被配置为在执行服务器线程时，能够利用的计算资源被限制到该每个服务器栈和耦合到该每个服务器栈的共享缓存块，从而将由服务器线程对客户端线程造成的核间干扰隔离到该每个服务器栈、耦合到该每个服务器栈的共享缓存块、耦合到该共享缓存块的任何服务器栈以及客户端栈内，从而实现SCE观感。
