OpenCL™ Code Analyzer in Intel® INDE Update 2

The new OpenCL™ Code Anlayzer, a feature of Intel® INDE OpenCL™ Code Builder, adds performance analysis capabilities integrated in your Microsoft Visual Studio* OpenCL development environment.

With this new feature, previously in preview, the OpenCL Code Builder now supports each state of the OpenCL code development, enables you to carry on performance optimizations in each step of the development from build, to debug, and to tuning and get the best out of Intel® Graphics Compute capabilities.

New tool available in beta: Vectorization Advisor

Software must be both threaded and vectorized to get the full performance benefit from today’s and tomorrow’s hardware.  Vectorization Advisor is a vectorization analysis tool that lets you identify loops that will benefit most from vectorization, identify what is blocking effective vectorization, explore the benefit of alternative data reorganizations, and increase the confidence that vectorization is safe.  

Vectorization Advisor is now available for beta test as a part of Intel® Advisor XE 2016. 

The Intel® Parallel Studio XE 2016 Beta program is now available!

Intel Parallel Studio XE 2016 is being made available now as part of a beta test program. In this beta test, you will have early access to Intel® Parallel Studio XE 2016 products and the opportunity to provide feedback to help make our products better. Registration is easy through the pre-Beta survey site

This suite of products brings together exciting new technologies along with improvements to Intel’s existing software development tools:

Android 开发之应用程序如何完全退出

之前忘记在哪看到一篇关于“android应用程序如何完全退出”的Blog,写的不错,我想这对很多人都有用,为了文章的原创,因此我结合了自己的代码环境,把这个经验分享给大伙。

第一步:创建一个Activity管理类,用来管理所有被用户点击过而没有被finish()掉的Activity:

 

Android 开发之 Vitamio 使用

Vitamio简介

MMS、RTSP (RTP, SDP), RTMP、HTTP progressive streaming、HLS - HTTP live streaming (M3U8)

Android 开发之浅谈广播的运用

之前讲过了activity,服务service和内容提供者,四大组件就还差广播没讲,所以就顺便讲讲吧。当然,这里都是很基础的讲解,没有深入,要是深入的话光一个activity就可以讲很久。所以这里只做基础使用的讲解了。

时间紧迫,直接上代码吧。

首先,广播有两种注册方式,一种在清单文件中注册,注册后程序一运行广播就开始监听。一种在代码中注册,根据需求注册注销广播。

我们先看广播的第一种注册方式,首先定义一个广播接受者
