Good Evening Team,

I installed openpbs server on virtual machine. and I want to add my compute and gpu node to the openpbs server. I tried but I cant add my nodes to openpbs.and also assign and sync a jobs on both nodes. Actually, I am beginner to the openpbs.

Kindly, help me to add both nodes as soon as possible.

qmgr -c “create node nodename”

where nodename is the hostname of the compute or gpu node
