There is the opposite side to this issue as well. Users running programs independent of the queue tends to defeat the "fair use" principles behind the queueing system. And it make node loads too high for users using PBS to get any substantial compute time. That said, given that OSCAR uses ssh for communication, how does one configure the compute nodes to block direct ssh access but allow PBS to operate normally? That is, how should ssh be configured (I assume sshd_config) to force users to run jobs through the queueing system? I have tried to do this once, but ended up blocking all users and root from remote access to the nodes.
