一句话介绍：The open standard for parallel programming of heterogeneous systems

OpenCL是面向异构系统的并行计算开放标准

OpenCL™ is the first open, royalty-free standard for cross-platform, parallel programming of modern processors found in personal computers, servers and handheld/embedded devices. OpenCL (Open Computing Language) greatly improves speed and responsiveness for a wide spectrum of applications in numerous market categories from gaming and entertainment to scientific and medical software.

OpenCL是用于在个人PC、服务器以及手持/嵌入式设备中的现代处理器上进行跨平台并行计算的开源标准，并且无需支付版权费。

OpenCL能够快速增加运算速度和响应能力，在广大行业中都有广泛的应用前景，包括游戏、娱乐、科学研究、医疗。
