我在AWS上使用p2实例,它应该有一个Tesla K80 gpu,里面有两个GK210 GPU(https://blogs.nvidia.com/blog/2014/11/18/tesla-k80-perf/)。
根据Nvidia论坛的以下帖子,我应该能够分别查看和访问这两个设备(https://devtalk.nvidia.com/default/topic/995255/using-tesla-k80-as-two-tesla-k40/?offset=4)。
但是,当我在p2实例上运行nvidia-smi时,我只看到一个设备:

如何监控和访问2台设备?
答案 0 :(得分:3)
带有p2.xlarge实例的actual situation是您为该VM分配了1/2的K80,因此此处的<link href="https://code.jquery.com/ui/1.12.0/themes/smoothness/jquery-ui.css" rel="stylesheet"/>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script src="https://code.jquery.com/ui/1.12.0/jquery-ui.js"></script>
<div id="highlights"></div>
输出是预期的,您将无法访问来自该VM /实例类型的2个GPU 设备。
