so, you have no graphics card, but you still want GUI management / X Windows......
Perhaps you do have a graphics card but want the convenience of using VNC to reach your Fedora machine?
There are some great turotials on getting the basics of VNC set up, but it always logs you right into the machine as a specific user...I want to choose my user....VNC + GDM is the answer

Torque 中，限制哪些Queue 只能在哪些 node 跑
12.1.3 Queues
Some resource managers allow queues (or classes) to be defined and then associated with a subset of available compute resources. With such systems, such as Loadleveler or PBSPro, these queue to node mappings are automatically detected. On resource managers which do not provide this service, Moab provides alternative mechanisms for enabling this feature.
12.1.3.1 TORQUE/OpenPBS Queue to Node Mapping
Under TORQUE, queue to node mapping can be accomplished by using the qmgr command to set the queue acl_hosts parameter to the mapping hostlist desired. Further, the acl_host_enable parameter should be set to False.

Just a quick follow on to the last post. If you try to use native IB support with GPFS instead of the IP over IB you need to set the verbsRdma to enabled. You also need to set the rdma device to use with the verbsPort setting. If you get the following error in /var/mfms/gen/mmfslog then you didn’t properly set the verbsPort
