Bernard,
Please ignore my previous email. I went to my lab and found out that those client nodes were shut down by some unknown reasons. Sorry for my previous question and I was very worried when the problem pop up. Michelle

Subject: [Oscar-users] how to add user to cluster
Hey,If I want to add a user to a cluster, it seems that I have to add user for each client node one by one. Say I have 8 client nodes, I have to do the same things for 8 times. Is there any way thatI only need to do once at the server node? Thanks, Michelle
