使用gdb调试命令gdb -ex "set breakpoint pending on" -ex "b nvmlShutdown" -ex "r" $(which nvidia-smi),强行在nvmlShutdown函数打断点,才能看到nvidia-smi加载了libnvidia-ml.so.1,具体的文件位置是在/lib/x86_64-linux-gnu/libnvidia-ml.so.1,是/lib/x86_64-linux-gnu/libnvidia-ml.so.550.54....

Reviewing System/GPU Topology and NVLink with nvidia-smi To properly take advantage of more advanced NVIDIA GPU features (such as GPU Direct), it is vital that the system topology be properly configured. The topology refers to how the various system devices (GPUs, InfiniBand HCAs, storage contr...
1. 如何发现GPU和NVLink:通过NVIDIA System Management Interface (nvidia-smi) 命令查看GPU设备及其相关信息。2. 如何初始化GPU和NVLink、NVSwitch:在程序中使用相应的API进行初始化,如CUDA Runtime API或驱动程序API。3. 如何构建GPU之间的可通信拓扑:使用CUDA的内置函数或者第三方库,如cuDNN等,构建可达的GPU网络...
nvidia-smi是用来查看GPU使用情况的。我常用这个命令判断哪几块GPU空闲,但是最近的GPU使用状态让我很困惑,于是把nvidia-smi命令显示的GPU使用表中各个内容的具体含义解释一下。 这是服务器上特斯拉K80的信息。 上面的表格中: 第一栏的Fan:N/A是风扇转速,从0到100%之间变动,这个速度是计算机期望的风扇转速,实际情...
