Hybrid Memory Cube Angles for Exascale

Computer memory is currently undergoing something of an identity crisis. For the past 8 years, multicore microprocessors have been creating a performance discontinuity, the so-called memory wall. It's now fairly clear that this widening gap between compute and memory performance will not be solved with conventional DRAM products. But there is one technology under development that aims to close that gap, and its first use case will likely be in the ethereal realm of supercomputing.

Green500 Turns Blue

The latest Green500 rankings were announced last week, revealing that top performance and power efficiency can indeed go hand in hand. According to the latest list, the greenest machines, in fact the top 20 systems, were all IBM Blue Gene/Q supercomputers. Blue Gene/Q, of course, is the platform that captured the number one spot on the latest TOP500 list, and is represented by four of the ten fastest supercomputers in the world.

NERSC Signs Up for Multi-Petaflop "Cascade" Supercomputer

The US Department of Energy's National Energy Research Scientific Computing Center (NERSC) has ordered a two-petaflop "Cascade" supercomputer, Cray's next-generation HPC platform. The DOE is shelling out $40 million dollars for the system, including about 6.5 petabytes of the company's Sonexion storage. Installation is scheduled for sometime in 2013.

Tackling the Data Deluge: File Systems and Storage Technologies

06/25/2012 | NetApp | A single hour of data collection can result in 7+ million files from just one camera. Collection opportunities are limited and must be successful every time. As defense and intelligence agencies seek to use the data collected to make mission-critical battlefield decisions, there’s greater emphasis on smart data and imagery collection, capture, storage and analysis to drive real-time intelligence. The data gathered must accurately and systematically be analyzed, integrated and disseminated to those who need it – troops on the ground. This reality leads to an inevitable challenge – warfighters swimming in sensors, drowning in data. With the millions, if not billions, of sensors providing all-seeing reports of the combat environment, managing the overload demands a file system and storage infrastructure that scales and performs while protecting the data collected. Part II of our whitepaper series highlights NetApp’s scalable, modular, and flexible storage solution to handle the demanding requirements of sophisticated ISR environments.
