IBM thinks exascale for massive Astron telescope

The sensitive radio telescope, due in 2024, will need processing horsepower that will be on par with several million of today's fastest computers.

IBM and Astron, a Netherlands-based astronomy organization, plan to develop an exascale computer system that will form the backbone of the largest and most sensitive radio telescope.

This exascale system will be designed for low-power usage and plug into the international Square Kilometre Array (SKA). SKA will be built out with the help of astronomers from more than 20 countries. The telescope will have millions of antennas and have a collection area of about one square kilometer. SKA will also be able to scan the width of the continental United States.

Under a 5-year, 32.9 million euro ($43.9 million) deal, the two groups will build the Astron & IBM Center for Exascale Technology. The telescope, due in 2024, will need processing horsepower that will be on par with several million of today's fastest computers. The project is funded by the Province of Drenthe, the Netherlands, and the Ministry of Economic Affairs, Agriculture and Innovation (EL&I). Astron (short for Netherlands Institute for Radio Astronomy) and IBM have collaborated before on the Blue Gene supercomputer, which analyzes data from Astron's low-frequency array.

The Astron telescope will aim to spot new galaxies, dark matter, and the origin of the universe. To accomplish that goal, the telescope will need a high-performance computing architecture and fast data transfer. The 5-year collaboration between Astron and IBM, dubbed DOME, will look at emerging technologies for everything from storage to analytics to develop the telescope. Data will be analyzed and collected daily.

That daily data stream will be equivalent to twice the world's Internet traffic each day -- a few exabytes a day for a single beam per one square kilometer. As with most analytics projects, the trick for Astron and IBM will be finding the key signals in that mass of information. IBM also gets to try out its 3D stacked chips and other technologies. As is the custom with IBM's research efforts, the company is looking to collaborate with outside scientists and then commercialize the findings.

IBM said that the location for SKA has to be finalized, but a decision is expected in 2012. Australia/New Zealand and South Africa are the two leading options to install the millions of antennas required.

A few key figures:

  • SKA will need to store 300 to 1,500 petabytes of data per year.
  • The CERN hadron collider stores 15 petabytes per year on average.
  • 18 exabytes is the limit of what today's 64-bit architectures can address.
  • SKA will aim to explore the universe dating back 13 billion years.

Details about Apple's 'spaceship' campus from the drone pilot who flies over it

MyithZ has one of the most popular aerial photography channels on YouTube. With the exception of revealing his identity, he is an open book as he shares with CNET's Brian Tong the drone hardware he uses to capture flyover shots of the construction of Apple's new campus, which looks remarkably like an alien craft.
