ParallelKnoppix is a modified Knoppix live CD designed for use in creating HPC clusters. You can start up PK on multiple nodes to run a cluster, and customize PK to add or remove applications.
To start PK, power on the computer with the CD in place. At the boot screen, just press Enter, unless you need to pass boot options to the kernel to get it to boot. For example, you might want to pass the acpi=no argument to the kernel if you have had problems getting PK (or other live CDs) to boot.
PK can also be used to run memtest to check the system memory. This is a good idea if you have any problems with the machine that you can't track down, such as programs crashing for no apparent reason.
After ParallelKnoppix has started, you might notice that it seems to be missing the menu bar.
