Android* 开发中的多线程编程技术

多线程这个令人生畏的“洪水猛兽”,很多人谈起多线程都心存畏惧。在Android开发过程中,多线程真的很难吗?多线程程序的“麻烦”源于它很抽象、与单线程程序运行模式不同,但只要掌握了它们的区别,编写多线程程序就会很容易了。下面让我们集中精力开始学习吧!

使用 OpenCL™ 2.0 读写图片

While Image convolution is not as effective with the new Read-Write images functionality, any image processing technique that needs be done in place may benefit from the Read-Write images. One example of a process that could be used effectively is image composition. In OpenCL 1.2 and earlier, images were qualified with the “__read_only” and __write_only” qualifiers. In the OpenCL 2.0, images can...

整理您的数据和代码: 数据和布局 - 第 2 部分

Apply the concepts of parallelism and distributed memory computing to your code to improve software performance. This paper expands on concepts discussed in Part 1, to consider parallelism, both vectorization (single instruction multiple data SIMD) as well as shared memory parallelism (threading), and distributed memory computing.

借助 SIMD 数据布局模板优化数据布局

Financial service customers need to improve financial algorithmic performance for models such as Monte Carlo, Black-Scholes, and others. SIMD programming can speed up these workloads. In this paper, we perform data layout optimizations using two approaches on a Black-Scholes workload for European options valuation from the open source Quantlib library.

已归档 - 面向增强现实的自主导航介绍

This article provides an introduction to autonomous navigation and its use in augmented reality applications, with a focus on agents that move and navigate. Autonomous agents are entities that act independently using artificial intelligence, which defines the operational parameters and rules by which the agent must abide. The agent responds dynamically in real time to its environment, so even a...
