The X11 Window System can be used to run a program on Biowulf and display thegraphics on a desktop or laptop. However, X11 can be unreliable and fail withmany graphics applications used on Biowulf. The HPC staff recommends NoMachine(NX) for users who need to run graphics applications.
NoMachine is a graphical client that presents a full virtual Linux desktop toa window on the user's local machine. It offers several features that makeit an improvement on the traditional local X11 server model:
- Improved display performance
- The ability to disconnect and connect without losing windows
- Uniform interface between Mac and Windows environment

You can either close the NoMachine client now, or double-click the Biowulf icon to start a session onthe Biowulf head node.
To start a session on the Biowulf head node, double-click the NoMachine icon.If you have already set up the client, you will see a screen that looks likeSlide 7 above. Double-click on the Biowulf icon.
Slide 8: the login screen. In the Username boxenter your NIH username, and enter your NIH AD password into the Password box.Please note that it is against NIH security policy to save your password in 3rdparty programs like the NoMachine client, and therefore it is important thatyou do not check the checkbox to save your password in the connectionfile.
By default, a series of help panels will be shown as you log into NoMachine.The first provides information about how to open the menus tocontrol NoMachine. It is possible to prevent these menus from beingdisplayed at the start of a session by checking the 'Don't show this messageagain' box at the lower left-hand corner. The next panel (slide 10)provides a little more information about what controls each menu item provides.Finally, the menu panel (slide 11) allows you to chose whether to display the menu panel as covering all the screen or as a window. We recommend the later as the more flexible option. Finally, you will get a panel(slide 12) to control the display resolution of your virtual desktop.
When these help panels have been displayed, you will see your desktop andit will be possible for you to start using your virtual Linux desktop.You should get a window that looks like slide 13, with a menu bar atthe top. Open a terminal window either by using the Applications menu in the upper left-hand corner of the screen, or by right-clicking anywhere onthe desktop window to call the pop-up menu and then select 'Open Terminal Here'.
While it may look like you have your ownLinux desktop to work with, the Biowulf head node where you are runningthis desktop services 600-800 users at a time, and therefore it is veryimportant that you not run computationally demanding jobs on the head node.To run jobs that are more demanding than a simple job submission, it is best to open a terminal window and then run the sinteractive command (slide 14).When you run sinteractive, you will be given an interactive shell running onone of the compute nodes with any graphical displays automaticallyredirected onto the NoMachine virtual desktop. You can test this for yourselfby calling up a terminal window, running the 'sinteractive' command in it, andthen running 'glxgears' as shown in slide 15.

If you do not get a menu bar at the top of the screen, it is possible to reset your desktop to default by performing the following steps:
- completely log out of your desktop session on Biowulf by opening aterminal window and entering the command
- exit NX
- log into biowulf with Putty or another SSH client and delete your desktopsettings by running
The next time that you log into biowulf with NX, your desktop will be recreated with the default settings.Configuration options are found by going to the upper-right corner (this isa user-selectable option) of the NoMachine window (look for the 'peel' effect)or by pressing control-alt-0 (zero). Be careful with the default settings thatyou don't accidentally press the 'close window' icon on Windows by mistake.Opening the configuration menu is below the Windows window controlicons.
Exiting: There is a difference between quitting the client and loggingout of the current session.
NoMachine is capable of continuing to run a remote session after you closethe client. If you use the window close button, or the 'disconnect'button in the connection section of the NoMachine window, then your sessionwill not be logged out or discontinued. It will continue running andconsuming system resources, and when you log in, you will have to either reconnect to that session or terminate it (users are currently limited toone NX session at a time). Please note that while sinteractive sessions willnot be immediately terminated, they will also not be suspended, and they willcontinue to run and burn time while disconnected. When they reach their walltime limits, any sinteractive sessions will terminate.
To log out and end a session when you are done with it, either click on yourname in the upper right-hand corner of the desktop window and select 'Log Out'from the bottom of the drop-down menu (Slide 1) and then press 'Log Out'in the pop-up menu (Slide 2), or run xfce4-session-logoutfrom a terminal window. This will completely log you out of that session onBiowulf.
Slow connection? If your session feels laggy or sluggish, there are two configuration optionsthat may improve the performance of the connection. Both of them are foundunder the 'change settings' section of the 'Display' option under the ControlPanel activated by clicking in the upper-right hand corner of the Desktopwindow. In the 'Display' menu, as show below, the 'Change settings' optionis found at the right side of the menu options:
The two options that have the most influence on session responsivity are'Display Quality' and 'Resolution'. They are controlled by the two slidersat the top of the control panel, as shown below:
