Half-Petaflop Supercomputer Deployed In Austin 130
SethJohnson writes "Thanks to a $59 million National Science Foundation grant, there's likely to be a new king of the High Performance Computing Top 500 list. The contender is Ranger, a 15,744 Quad-Core AMD Opteron behemoth built by Sun and hosted at the University of Texas. Its peak processing power of 504 teraflops will be shared among over 500 researchers working across the even larger TeraGrid system. Although its expected lifespan is just four years, Ranger will provide 500 million processor hours to projects attempting to address societal grand challenges such as global climate change, water resource management, new energy sources, natural disasters, new materials and manufacturing processes, tissue and organ engineering, patient-specific medical therapies, and drug design."

And you could *TRY* to build a 15,744 single core machine and claim the same performance, but it would all fall apart very very quickly when someone asks "how many FLOPS?" (which is what computing power should be measured in, regardless of how many cores it has).

Explanation: this affirmation that "a computer is so fast it runs an infinite loop in X seconds" is actually true. Integers overflow, if you increase the largest positive number you get a negative number. But of course, this program uses 32-bit integers, it would take four billion times longer running in 64 bits.
