The Cray 500k supercomputer

Around a decade ago just around 100 or so facilities could justify the expense of a supercomputer. Nowadays their is a real need for them for as prices
are falling enough where it could provide ROI easily in today’s demand of data analysis.
Apparently Cray has a low cost supercomputer, the Cray XC-30AC priced around 500,000 starting which is way less than the typical 10-30 million dollar price tag of the XC-30 version.

Exascale Computing

Titan is capable of 20,000 trillion calculations per second or 20 petaflops and is operated by Oak Ridge National Laboratory, part of the U.S. Department of Energy’s network of research labs. The ultimate goal is to build a 1,000 petaflops supercomputer.
