To Uninstall Hosts

You can remove one or more compute hosts from the compute grid.

When you uninstall a compute host, the N1GE software is shut down and removed from the selected hosts. The N1GE master host is instructed to remove those compute hosts from the N1GE compute grid.

Before you start the uninstall procedure, ensure that no jobs are running on the compute hosts that you want to uninstall. Any jobs that are currently running on these hosts will be terminated. If the jobs are marked as “re-runnable”, they are automatically resubmitted to the N1GE compute grid for execution on another compute host(s). However, if they are marked as “not re-runnable,” then they are not rescheduled and are not automatically executed elsewhere.

Steps

1. Select Grid Engine > Uninstall Host.

   The selector appears, displaying the list of hosts currently in the compute grid; see Uninstalling Hosts.

2. Click to highlight a host(s). You can also click Select All at the top to choose all hosts in the list.

3. Click Uninstall Selected Nodes in the bottom right corner.

   The Uninstall Task Progress Dialog appears.
