It’s the Sum, Not the Parts
Computer architects create something of functional beauty, just as do their cousins who work in the more tangible media of rock and stone. Consider John Cocke and the IBM 801, Ken Batcher and the Goodyear MPP, Tadashi Watanabe and the NEC SX. Similarly, Seymour Cray’s designs balanced many aspects of power engineering, packaging and cooling,…

Luck Is a Fickle Friend
As an enterprising young faculty member, I asked Professor Slotnick if he had any words of wisdom to offer a young parallel computing researcher, based on his experience with ILLIAC IV. He simply said, “Choose your risks carefully.”

The reason we strive to protect data centers is obvious, their failure often has catastrophic business implications. Without doubt, though, some workloads are less affected by failure than others. If your web search for basket weaving supplies times out, you are probably content to retry the query a few seconds later. If your attempt to…

I pedaled home in time to watch the Apollo 11 lunar landing later that afternoon, holding the cardboard model of the LEM in my hands. That…

IT’s Not Easy Being Green (Actually, It Is Easy If You Try)
In the interview, I pointed out that the most obvious way to reduce computing-related energy consumption is simply to power down and turn off those systems not being used – QED. However, that is insufficient alone. After all, one presumably wants to do some computing. Thus, systems and infrastructure must be designed for energy and…
