The USB stick holds workshop material including the training material and presentations, abstracts, and program. In addition, it contains a fully operational Linux operating system based on Kubuntu with OpenFOAM (versions 1.6-ext and 1.7.1) and many other related packages already installed. The extra packages include eclipse, enGrid, ParaView, pyFoam, pythonFlu, swak4Foam and more. The idea is that all attendees should be able to boot their computers from the USB stick so that everyone can work in a common environment.
Reasons that you might not be able to boot from the USB stick include the following:
If you are not able to boot from the USB stick, you can get the same effect by using virtualization software such as VirtualBox (which is free). See Section 8.
On non-Mac laptops, you can boot from the USB stick as follows:
Note this distinction: Booting your machine from the USB stick and choosing to ``Try Kubuntu without installing'' will not change your normal operating sytem in any way. Later, if you like, you have the option of installing Kubuntu and the included software on your computer permanently.
Wireless internet access will be available to visitors. Check your wireless network signal for the Visitor Wireless network named attwifi, connect to it, and then open your web browser to launch the AT&T Wi-Fi web screen. Attendees will receive daily prepaid coupons at registration with a scratch-off access code.
Call 1-888-888-7520 for AT&T Wi-Fi support. Additional instructions are also available at wireless.psu.edu/visitorwireless.html.
If you have booted your laptop from the USB stick, then the USB stick holds approximately 800 MB of persistent memory, which will allow any changes you make to the workshop materials or to your home directory to ``persist'' from one boot to the next.
If you are using the material under VirtualBox, you may need to select ``Save the machine state'' rather than ``Shutdown'' in order for changes to persist, or else make your changes only to Shared Folders (folders that are shared with the host computer).
Only a limited amount of persistent storage space is available on the USB stick, and that space will be further decreased as updated workshop materials are added. If additional space is needed, it can be obtained by using your own internal hard drive or a second flash drive.
You will need to mount the additional storage to make it available for use. One way to do this is using the dolphin ``File Manager'' available from the ``KDE Kickoff Application Launcher'' in the lower right corner of the screen. Launch the File Manager, and on the left side of the window will be a ``Places'' window frame. Select the appropriate drive from the list. The middle frame will show the contents of the drive. Open up a terminal and execute cd /media/XXXX, where XXXX is the mount point for the drive. The df command will show all of the mounted devices and their mount points.
It is suggested that you then cd to a portion of the file system to which you have write access and where your modifications will not compromise the integrity of the file system. For example, if you mount a Linux file system, it is suggested that you use your home or tmp directory and make a working directory under it.
VirtualBox is virtualization software for Windows, Linux, Macintosh and Solaris hosts that is freely available as Open Source Software under the terms of the GNU General Public License (GPL). VirtualBox can be downloaded from www.virtualbox.org. From the Downloads page, download the appropriate binary for VirtualBox as well as the Oracle VM VirtualBox Extension Pack.
On non-Mac laptops, it may be possible to build the virtual machine by choosing the USB device. In general, it may be easier to build the virtual machine based on the OFW6 ISO file (i.e. the USB stick contents in the form of a file).
The ISO file is available during the workshop at rcc.its.psu.edu/ofw6/. After the workshop, it will be available at sourceforge.net/projects/openfoam-extend/. If the ISO file is downloaded in the form of multiple RAR files, these files can be unarchived and recombined into an ISO file using free software such as UnRarX, available for macs at www.unrarx.com. To use UnRarX, simply start the application and drag the first (part1) file into the main window.
After installing VirtualBox, create a virtual machine based on the OFW6 ISO file following these instructions:
