CUDA Runtime API (PDF) - v12.8.1 (older) - Last updated March 04, 2025 - Send Feedback 1. Difference between the driver and runtime APIs The driver and runtime APIs are very similar and can for the most part be used interchangeably. However, there are some key differences worth not...

The CUDA Toolkit includes libraries, debugging and optimization tools, a compiler and a runtime library to deploy your application. You'll also find code samples, programming guides, user manuals, API references and other documentation to help you get started. Libraries cuRAND NPP Math Library ...
Runtime API是一组函数,用于在编写CUDA程序时执行核函数之前分配和释放设备上的内存、将数据从主机复制到设备并执行核函数等任务。CUDARuntime API被打包放在CUDAArt包里,其中的函数都有CUDA 前缀。CUDA运行时没有专门的初始化函数,它将在第一次调用函数时自动完成初始化。对使用运行时函数的CUDA程序测试时要避免将...
https://docs.nvidia.com/cuda/pdf/CUDA_Runtime_API.pdf 一,cuda graph的优势 主要是解决一堆算子在调用,运行时的cuda launch部分所产生的重复开销 并没有对kernel内部产生优化也没有做fusion之类的优化,但是如果你的graph并不能被复用,那就会每次都产生新的graph,就违背了我们的初衷,那要如何才能保证我们能高...

这里主要有两点用途,一点是CUDA Context在DriverAPI和Runtime API混合调用时候的帮助。我们知道runtime api是没有context这个概念的,而driver api有。同时runtime api稍微易用点,而driver api稍微难用点。而很多代码,例如NV的Video CodecSDK的例子中,很多代码使用的driver api进行的。则本小节指出了,可以通过特殊的...
CUDA有两个主要的API:runtime(运行时) API和driver API。这两个API都有对应的CUDA版本(如9.2和10.0等)。 用于支持driver API的必要文件(如libcuda.so)是由GPU driver installer安装的。nvidia-smi就属于这一类API。 用于支持runtime API的必要文件(如libcudart.so以及nvcc)是由CUDA Toolkit installer安装的。(CUDA...
