If you don’t want to read my blather, then go immediately over to:
In this paper a comparison of the Traditional OS Architectures is made with respect to the needs of an efficient multikernel based operating system. The researchers discuss how they used a Rocky Lake Board, (from Oracle) to test the system. The findings are discussed in detail, and since this paper can be viewed for no cost by my readers, I won’t detail them here.
Seriously, if you have P.O.S. x86 laying about, you can load up the BarrelFish O/S and get started doing research. So just do it!
