Little FE Notes

In order to run all of our modules, Little FE needed some tweaking. This page documents those, and also notes on using Little FE in general.

Running Little FE
Once all of the nodes are running (it takes a little while), run the following commands: A better way is the script /root/bin/cluster.bash. It is recommended to just sudo run this script.

Connect the Wireless Keyboard
If you want to use the wireless apple keyboard, run the command (with keyboard on)

Shutdown the Nodes
This will kill all of the nodes painlessly:

Wireless Networking
Our Little FE setup does not have two Ethernet ports, so we had to use wireless. Wireless can be enabled with the commands (see /root/bin/wireless.bash: Note that the ESSID will change from location to location.

Internet via NAT
Since wireless was not working (due to netreg troubles), we connected Little FE to the internet via Castaway. To change this behavior, Note that the NAT behavior can be re-enabled by using files with the .nat suffix. Certain assumptions are made, such as the IP of Little FE being 10.0.0.30. Also, note that the resolv.default file assumes we are at St. Olaf.

Open MPI
We used our own (64-bit) build of Open MPI. This solves the problem of the ones that were on there being 32-bit.

Additional Modules
We added:
 * Intel Threading Building Blocks (TBB) 4.0.3
 * Boost 1.49.0
 * Open MPI 1.4.0 (64-bit)
