The IBM PowerPC 970 CPUs are well-designed, high-performance chips that ship in millions of end-user systems under Apple Computers’ Power Macintosh G5 moniker. These CPUs greatly lower the bar for 64-bit computing on the desktop and on small servers. Currently, Terra Soft’s beta Y-HPC is one of only two 64-bit Linuxes that run on G5s. As their names imply, the G5-enabled betas — both 32- and 64-bit versions — are for evaluation only. This article is an early look at the promise of Linux on a G5 and is intended for developers interested in trying out this combination in anticipation of production-ready releases to come.
