Can a compute node be actually used as a host for submitting jobs?
• Yes, in most cases you can use the host node as a compute node and submit jobs from it. For instance, in Torque resource manager, along with installing the server on the head node you also install and run the mom client on the head node. • At this point, the host node also shows up as a compute node and you can submit jobs. However, using the host node as a compute node to submit jobs has its drawbacks. If a large job that takes a lot of processing power is submitted, then the entire cluster can be slowed down.
