GPU status checking in Ubuntu

Currently, we are maintaining four clusters: mark0, mark1, mark2, mark3.
For checking GPU status, mark0 works as a server where each client (clusters including mark0) runs a shell script informing GPU usages.

Server Setting

In mark0, run

$ sh run_server.sh

Client Setting

For every clusters, run

$ nohup ./gpu_daemon.sh mark0 > /dev/null &`
