限制nvidia-docker中的GPU使用率？

Question

我在多GPU服务器上设置内部Jupyterhub。 Jupyter访问是通过docker实例提供的。我想将每个用户的访问权限限制为不超过一个GPU。我很感激任何建议或评论。感谢。

Answer 1

您可以使用nvidia-docker-compose

进行尝试

version: "2"
services
  process1:
    image: nvidia/cuda
    devices:
      - /dev/nvidia0

Answer 2

问题可以通过这种方式解决，只需在“nvidia-docker”之前添加环境变量“NV_GPU”，如下所示：

 [root@bogon ~]# NV_GPU='4,5' nvidia-docker run -dit --name tf_07 tensorflow/tensorflow:latest-gpu /bin/bash
e04645c2d7ea658089435d64e72603f69859a3e7b6af64af005fb852473d6b56
[root@bogon ~]# docker attach tf_07
root@e04645c2d7ea:/notebooks#
root@e04645c2d7ea:/notebooks# ll /dev

或，阅读nvidia-docker of github's wiki

Answer 3

共有3个选项。

具有NVIDIA RUNTIME（版本2.0.x）的Docker

根据official documentation

employee_id   employee_name   motor_id
--------------------------------------
1             jack            2
2             john            1

nvidia-docker（版本1.0.x）

基于popular post

select motor_types from tbl_motor

（它与tensorflow一起使用）

以编程方式

tbl_employee
