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. Figure 4. GPU Computing ...
不能使用 cudaMalloc() 来申请(实验表明只能获得空指针)或 cudaMemset()(限定 __host__ 函数)和 cudaFree() (函数不配套)。 ● 主机中使用 cudaMalloc() 仅受限于可使用的设备内存,而设备代码中中使用 malloc() 受限于设备堆内存申请上限参数 cudaLimitMallocHeapSize,可能需要在申请前临时修改(类似修改 printf...

作为使用nvcc编译CUDA C ++设备代码的替代方法,NVRTC可用于在运行时将CUDA C ++设备代码编译为PTX。 NVRTC是用于CUDA C ++的运行时编译库;有关更多信息,请参见《 NVRTC用户指南》。 Binary Compatibility 二进制代码是特定于体系结构的。 使用指定目标体系结构的编译器选项-code生成cubin对象:例如,使用-code = sm...
[翻译]CUDA-C-Programming-Guide Maximize InstructionThroughput 技术标签: CUDA5.4 最大化指令吞吐量 为了达到最大的指令吞吐量,程序应该: 最小化使用低吞吐量的计算指令;有以下方法:在不影响结果的情况下以精度换取执行速度,比如使用指令来代替内置函数,用单精度代替双浮点精度,或者将非归一化数据刷新为0. 最小化...
主要内容来源于NVIDIA的官方文档《CUDA C Programming Guide》,结合了另一本书《CUDA并行程序设计 GPU编程指南》的知识。 因此在翻译总结官方文档的同时,会加一些评注,不一定对,望大家讨论指出。 另外,我才不会老老实实的翻译文档,因此细节还是需要从文档里看的。
