云计算(Cloud Computing ):是分布式处理(Distributed Computing)、并行处理(Parallel Computing)和网格计算(Grid Computing)的发展,或者说是这些计算机科学概念的商业实现。是指基于互联网的超级计算模式--即把存储于个人电脑、移动电话和其他设备上的大量信息和处理器资源集中在一起,协同工作。在极大规模上可扩展的信息...
Distributed computing involves the coordination of tasks across multiple interconnected nodes, whereas cloud computing acts more as an on-demand service to a node that pulls information from a centralized, shared pool of resources. What is distributed computing vs parallel computing?
Parallel Computing vs. Distributed Computing While often used interchangeably, parallel and distributed computing have distinct characteristics: Parallel Computing Involves multiple processors carrying out calculations simultaneously, typically within a single machine or tightly coupled system. All processors have ...
(Figure 9.16).Distributed computing systemsare usually treated differently fromparallel computingsystems or shared-memory systems, where multiple computers share a common memory pool that is used for communication between the processors. Distributed memory systems use multiple computers to solve a common ...

例如, 在 Stale Synchronous Parallel (SSP)中,系统跟踪各个工作节点的进度并维护最慢进度,通过动态限制进度推进的范围,保证最快进度和最慢进度的差距在一个预定的范围内。这个范围就称为“新旧差阈值” 半同步并行通过对于更新的不一致程度的限制,以达到收敛性居于同步并行和异步并行之间的效果。除了同步时机的区别,...
题外话,完全并行通常称作密集并行(Embarrassingly parallel),或者用政治正确的话来说,愉悦并行(pleasantly parallel),它拥有最佳的扩展性能(速度与处理器的数量呈线性关系)。当然,对此不必感到尴尬!不幸的是,密集并行很少见。 让我们给阿姆达尔定律添加一些数字。假定,算法在单处理器耗时100秒。再假设,并行分量为99%,这个...
