linux - monitor gpu state

Before using nvidia-smi, can only show resource usage server can not see who is in use.

Found gpustat pretty good, you must first install it:

pip install gpustat

use:

 

gpustat

 

Options:

--color : Force colored output (even when stdout is not a tty)
--no-color : Suppress colored output
-u, --show-user : Display username of the process owner
-c, --show-cmd : Display the process name
-p, --show-pid : Display PID of the process
-P, --show-power : Display GPU power usage and/or limit (draw or draw,limit)
--watch, -i, --interval : Run in watch mode (equivalent to watch gpustat) if given. Denotes interval between updates. (#41)
--json : JSON Output (Experimental, #10)
Tips
To periodically watch, try gpustat --watch or gpustat -i (#41).
For older versions, one may use watch --color -n1.0 gpustat --color。
Running nvidia-smi daemon (root privilege required) will make the query much faster and use less CPU (#54).
The GPU ID (index) shown by gpustat (and nvidia-smi) is PCI BUS ID, while CUDA differently assigns the fastest GPU with the lowest ID by default. Therefore, in order to make CUDA and gpustat use same GPU index, configure the CUDA_DEVICE_ORDER environment variable to PCI_BUS_ID (before setting CUDA_VISIBLE_DEVICES for your CUDA program):
export CUDA_DEVICE_ORDER=PCI_BUS_ID.
