Linux Clustering using the PowerPC G4 Processor

D. Grieg, C. Collins, T. Benjegerdes, and B. Bode (USA)



Beowulf style clusters have become commonplace, but generally use x86 or alpha processors. We will present results obtained through the construction and use of a 48 CPU cluster based on PPC G4 processors running a PPC Linux distribution. We will examine the benefits and the pitfalls to using COTS PPC based hardware from Apple Computer and PPC Linux software. Included is a comparison of the use of Fast/Gigabit Ethernet built-in to each system to Myrinet hardware. In addition the PPC based cluster will be compared to more conventional clusters based on a variety of measures and for a variety of problems.
