The sas customer-analytics application was integrated into this environment using datasynapse gridserver to connect and parallelize application-service requests to scale effectively when distributed across a grid computing infrastructure sas客户分析应用程序是使用datasynapsegridserver集成到这种环境中的,以便连接和并行处理应用-服务请求,这样,在网格计算基础设施上进行分发时,就可以有效地进行缩放。
In this paper, we use a simple but effective form of wavefront parallelism to parallelized fastlsa algorithm, which we called parallel fastlsa . compared with fastlsa algorithm, it further improves the time performance, while still use only linear space 为了进一步改进fastlsa算法性能,本论文利用一个简单而有效的“波阵线机制”对fastlsa算法进行了并行化处理,本文称这种经过并行处理的fastlsa算法为并行fastlsa算法。
Developers often seek performance improvements in the " infrastructure " of an application, like keeping the set-up time low through database connection caching, parallelizing calls, preparing xml parsers or serializers before the actual call, and much more 开发人员通常在应用程序的“基础结构”中寻求改进性能的方法,例如通过数据库连接高速缓存、并行调用、在实际调用之前准备xml解析器或序列化器来缩短设置时间,还有其它更多的方法。
Because most programs are more complex than a matrix-multiplication problem ( which can be completely parallelized with speedup close to 100 %, assuming you have enough processors ) we must synchronize our threads and protect globally shared data across multiple threads 由于大多数程序都比一个矩阵乘法问题(假如你有足够的处理器,这个问题可以完全并行化从而得到近乎加倍的运算速度)复杂,我们必须同步我们的进程在多线程中并保护全局共享数据。
Fundamentally, both vector and scalar processors execute instructions based on a clock; what sets them apart is the ability of vector processors to parallelize computations involving vectors such as matrix multiplication, which are commonly used in high performance computing 从根本上来讲,向量处理器和标量处理器都是基于时钟周期来执行指令的;使它们产生区别的是向量处理器并行处理与向量有关的计算的能力(例如矩阵乘法),这在高性能计算中是非常常见的。
Ixp c, as a parallelizing compiler, is designed aiming at parallel maximization in the sequentially semantic applications by parallelizing them and mapping them to the hardware units of the network processor, which abstract away most of the hardware details for programmers to let them focusing on logics of the programs, facilitates the development of high performance network applications executing on network processors, and thus brings good portability and expandability for the programs 它将串行语义的程序并行化,并适当的映射到网络处理器的硬件架构上。这一特性为网络应用程序的开发者屏蔽了网络处理器的硬件细节,使其仅关注于网络应用程序本身的逻辑。这便利了网络处理器之上的高质量高性能的网络处理程序的开发,并使其具有良好的可移植性与可扩充性。
