Remote desktop

    Question

  • Is it ok for me to allow users to remote desktop the compute nodes in the cluster? 
    In other words, will the performance of the cluster be degraded if the users connect to the compute nodes via remote desktops? And, is the cluster smart enough to use the processors from the nodes that are not busy when jobs are scheduled? 

    Thanks in advance.

  • Hi Emad,

    It should be fine to enable RDP to compute nodes on your cluster, however, applications users run on the compute nodes will use CPU, I/O, and storage resources, of course. This usage may impact jobs scheduled by the job scheduler.

    The job scheduler keeps track of where it has scheduled work but it does not look at current CPU utilization as part of it's scheduling algorithm. If you are using compute nodes as both desktop machines (using RDP) and as compute nodes then there may be issues since the job scheduler assumes each node is fully dedicated to being a member of the cluste.

    Thank you,
