cuda driver API设计的这一套cuda context的管理,本意是为了防止不同的代码之间相互干扰,比如A代码用着cuda context,突然被B代码销毁了,为了防止这种问题,A代码可以自己单独用一个cuda context,每当A代码要用GPU的时候就把自己的cuda context推到栈顶。 然而,后来发生了一些改变,有了cuda runtime API之后,没有人再...
Driver API允许开发人员更详细地控制GPU的行为,包括访问GPU硬件资源、配置GPU寄存器和指令流等。CUDA Driver API是一种基于句柄的底层接口(式多对象通过句柄被引用),可以加载二进制或汇编形式的内核函数模块,指定参数,并启动计算。CUDA Driver API的编程复杂,但有时能通过直接操作硬件的执行实行一些更加复杂的功能键,或...
当遇到"CUDA error: an illegal memory access was encountered"错误时,一个实际应用场景是图像处理。以下是一个示例代码的片段,展示了如何使用CUDA进行图像的平滑处理: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 pythonCopy codeimportcv2importnumpyasnpimportpycuda.autoinitimportpycuda.driverascuda from ...
The first mechanism is a callback API that allows tools to inject analysis code into the entry and exit point of each CUDA C Runtime (CUDART) and CUDA Driver API function. Using this callback API, tools can monitor an application’s interactions with the CUDA Runtime and driver. The seco...

If you want to use the driver API to load a linked cubin, you can request just the cubin: nvcc --gpu-architecture=sm_50 --device-link a.o b.o \ --cubin --output-file link.cubin The objects could be put into a library and used with: nvcc --gpu-architecture=sm_50 --device-...

By default, the CUDA compiler driver nvcc embeds cubin files into the host executable file. But they can also be generated separately by using the “-cubin” option of nvcc. cubin files are loaded at run time by the CUDA driver API. Note For more details on cubin files or the CUDA ...
