THE "MACHINE" FROM HP

HP has abruptly changed course on its 'Machine,' a new type of memory-driven computer it thinks will radically alter large-scale data processing. When the company first launched it last year, the plan was to use a new kind of memory chip called the "memristor," which is as fast as DRAM but can permanently store data. The problem is that the tech, which HP expected to commercialize with Hynix in 2013, still isn't ready. Rather than giving up, though, HP has decided to take it in another direction by using both conventional RAM and phase change memory.
HP figured the Machine would replace data server farms with a computer the size of refrigerator using a fraction of the power. To do that, it would compute using specialized core clusters, photonic circuits and a huge pool of unified memory. For the latter, it depended heavily on the memristors -- which store data with no power -- and company researchers insisted that any other technology just wouldn't do. It has scaled that ambition back, however, and chief technology officer Martin Fink now says that for now, it'll be a "memory-driven" Linux computer based on DRAM. "We way over-associated this with the memristor," he told the New York Times.
