在 vSphere Bitfusion 中分配 GPU
要为单个应用程序分配多个 GPU，请运行 bitfusion run 命令。
要分配多个 GPU 并启动会话以便在相同 GPU 上运行多个应用程序，请运行 bitfusion request_gpus。
在 vSphere Bitfusion 中运行应用程序
要启动单个应用程序，请运行 bitfusion run 命令。
要在使用 bitfusion request_gpus 命令启动的会话中启动多个应用程序，请运行 bitfusion client 命令。
在 vSphere Bitfusion 中解除分配 GPU
要在使用 bitfusion request_gpus 命令启动的会话中解除分配 GPU，请运行 bitfusion release_gpus 命令。
列出 vSphere Bitfusion 中的可用 GPU
要验证 vSphere Bitfusion 服务器安装并查找可用 GPU 列表，请运行 bitfusion list_gpus 命令。
- server 0 [172.16.31.162:56001]: running 0 tasks |- GPU [0]: free memory (15109 / 15109MiB) Tesla T4 (7.5) - server 1 (leader) [172.16.31.156:56001]: running 0 tasks |- GPU [0]: free memory (15109 / 15109MiB) Tesla T4 (7.5)
在 vSphere Bitfusion 中执行运行状况检查
可以从命令行访问运行状况检查。
- 要检查所有 vSphere Bitfusion 服务器和 Bitfusion 客户端的运行状况，请运行 bitfusion health。
- 要检查单个 vSphere Bitfusion 客户端或服务器的运行状况，请运行 bitfusion localhealth。
检查 vSphere Bitfusion 版本
要显示 vSphere Bitfusion 的安装版本，请运行 bitfusion version 命令。
Bitfusion version: 4.0.0 release
在 vSphere Bitfusion 中显示 GPU 信息
要显示 GPU 信息，请运行 bitfusion smi 命令。或者，要收到类似的输出，可以使用 bitfusion run 命令启动 nvidia-smi 应用程序。
