  • 使用英特尔® 智能存储加速库优化存储解决方案

    随着越来越多的设备连接到云/互联网,出现了各种不同的源(包括智能手机、平板电脑和物联网设备)生成数据。 存储需求逐年攀升。  英特尔® 至强™ 处理器产品家族和英特尔® 智能存储库(英特尔® ISA-L)的结合为可发人员提供了安全、快速处理数据,甚至降低存储空间需求的工具。

    在中国,英特尔与奇虎 360 科技有限公司合作将英特尔 ISA-L 集成至其存储解决方案。 这使得其性能提升了 10 倍,存储空间需求降低了 2/3。 阅读案例研究

    英特尔® ISA-L 可帮助加速和优化任何设备(从小型的办公 NAS 设备到企业级存储系统)上基于英特尔® 架构 (IA) 的存储。   本库中提供的函数可在存储可恢复性、数据完整性、数据安全性提供帮助,并可加速数据压缩机制。  本文从较高的层面对英特尔 ISA-L 的函数进行了概述。

    英特尔 ISA-L 在存储应用中使用了以下函数:

    Part1. Vectorization of loads/stores group.

    GCC 5.0 significantly improves vector code quality for load groups and store groups. By loads/stores group I mean iterated consecutive sequence of loads/stores. For example:

    x = a[i], y = a[i + 1], z = a[i + 2] iterated by “i” is loads group of size 3

    Group size is distance between smallest and largest loads/stores addresses. In the example (i + 2) – (i) + 1 = 3

  • Getting the Most out of your Intel® Compiler with the New Optimization Reports

    The performance improvement an application gets from being compiled with optimization can be enhanced by understanding and acting on optimization reports. Fortunately, this has become much easier with the latest compilers from Intel. Modern optimizing compilers can often make code transformations that greatly improve application performance, but this may depend on how the original code is written and how much information is available to the compiler.
