Running Software the Easy Way

Learn how to use X server software on your local machine to run software on the cluster.

An easy way to run software on the cluster is with X server software on your local machine. If you are on a Windows computer, we recommend that you use the NX client. Most Linux and Windows computers come with a built-in X server, although you can install the NX client or another client of your choice.

Here are instructions for using the the NX client to access the cluster software:

1. Configure the client to connect to fructose.cchmc.org (the cluster headnode). See Configuring the NX client for details.

Note

To connect to fructose, you need to be connected to the Cincinnati Children's network directly or through VPN.

2. Use the NX client to connect to fructose.cchmc.org with the user name and password you have been provided to access the cluster.

NX provides you a KDE or Gnome desktop session:

3. To launch software, use the desktop icons available for most of the GUI-based software available in the cluster (like GeneSpring, Matlab, AutoDockTools and R):

Or, in your KDE menu, go to the Cluster program group, and select a software application from the list:

4. When you submit a job, you can change the default resource values (900 MB memory and 1 Hour walltime) by clicking No at the following screen:

5. Enter custom values for memory and walltime, and click Submit Job.
