CUDA comes with a software environment that allows developers to use C as a high-level programming language. As illustrated byFigure 4, other languages, application programming interfaces, or directives-based approaches are supported, such as FORTRAN, DirectCompute, OpenACC. ...
CUDA带来了一个允许开发者使用C++作为高级编程语言的软件环境。许多其他的语言、接口以及基于指令的方法也是支持的,例如Fortran、DirectCompute、OpenACC。 1.3 可扩展编程模型 多核CPU和众核GPU的出现意味着主流处理器芯片变成了并行系统。现在的问题在于,如何设计一个能够无缝扩展到核心数量日益增加的处理器上,就像3D图形...
如图 1-3 所示,其它的语言和应用编程接口(API )也被支持,如CUDA FORTRAN,OpenCL 和Direct Compute 。 图1-3. CUDA 设计为支持多种语言和应用编程接口 1.3 一种可扩展的编程模型 多核CPU 和众核GPU 的出现,意味着主流处理器芯片现在已经是并行系统了。 更进一步的说,他们的并行度将继续以摩尔定律扩展。面临...
CUDA™是一种由NVIDIA推出的通用并行计算架构,该架构使GPU能够解决复杂的计算问题。 它包含了CUDA指令集架构(ISA)以及GPU内部的并行计算引擎。 开发人员可以使用C语言来为CUDA™架构编写程序,所编写出的程序可以在支持CUDA™的处理器上以超高性能运行。CUDA3.0已经开始支持C++和FORTRAN。
CUDA也支持C/C++/Fortran/Python/JAVA等多种语言,进一步方便了使用。CUDA中还封装了大量的成熟且经过充分优化的数学库。 图:CUDA支持的编程语言 图:CUDA提供的数学库和对应功能 参考资料 CUDA C Programming Guide CUDA C Best Practices Guide https://docs....
