IBM demonstrated a blade server board based on the Cell architecture at the E3 show this week, and reportedly plans to sell the boards in rack-based server systems. The board carried two Cell processors running at up to 2.8Ghz, as well as 1GB of DRAM split across two chips, according to Nikkei’s TechOn service (http://techon.nikkeibp.co.jp/english/NEWS_EN/20050525/105050/). The demo box ran on Linux.The chips have been clocked at 3GHz in the lab, according to an IBM engineer quoted by TechOn, meaning theoretical performance of 400Gflops for a two chip board. Unsurprisingly, perhaps, the demo board featured chunky heatsinks and fans. However, IBM...
