CUDA vs OpenCL,两种不同的 GPU 计算工具,尽管部分功能相似,但是本质上其编程接口不同。 CUDA 是什么? CUDA 是统一计算设备架构(Compute Unified Device Architecture)的代表,这个架构是 NVIDIA 于 2007 年发布的并行编程范例。CUDA 使用类 C 语言,用于开发图形处理器软件和大量 GPU 通用应用程序,这些应用程序本质...
本节根据学术上对CUDA和OpenCL的研究,比较两者的性能,其中本文简单以[1-3]研究成功比较CUDA和OpenCL之间的性能差异,若需详细了解CUDA和OpenCL之间的性能差异可以参考[4-15]。 3.1 AES实现 Wang[1]提出一种在XTS模式的AES实现,并对OpenCL和CUDA性能进行比较。总体性能CUDA要比OpenCL好10%~20%之间。 3.2 三维可...
同个程序OpenCL的速度只有CUDA的1/3。另外OCL抽象层及比较低,以至于开发起来有点麻烦。
This paper presents a comparison between two architectures for parallel computing: Compute Unified Device Architecture (CUDA) and Open Computing Language (OpenCL). Some works in the literature have presented a computational performance comparison of the two architectures. However, there is not any ...
OpenCL AMD vs NVIDIA performance I implemented a simple kernel which is some sort of a convolution. I measured it on NVIDIA GT 240. It took 70 ms when written on CUDA and 100 ms when written on OpenCL. Ok, I thought, NVIDIA compiler is better optimized for CUDA (or I'm doing ...
This thesispresents the CUDAtoOpenCL source-to-source tool that translates code from CUDA to OpenCL, thus ensuring portability of applications on a variety of devices. However, current compiler optimizations are not sufficient to translate performance from a single expression of the program onto a ...
CUDA是一个软件层,可以直接访问GPU的虚拟指令集和用于执行计算内核的并行计算元素。除了驱动程序和运行时...
This PR aims to add support for CUDA and OpenCL. Once ready, I'll need someone to test CUDA support since I don't own an Nvidia card myself. Testing instructions Just a warning, old models as downl...
