IEEE Group Seeks to Reinvent Computing as Scaling Stalls

May 6, 2015 |

Computer scientists worried about the end of computing as we know it have been banging heads for several years looking for ways to return to the historical exponential scaling of computer performance. What is needed, say the proponents of an initiative called “Rebooting Computing,” is nothing less than a radical rethinking of how computers are Read more…

Fractal Art Combines Math and Computing

May 12, 2014 |

You don’t need to be a mathematician to appreciate the beauty and elegance of fractal geometries, those infinitely complex patterns that are self-similar across different scales. Recently, a group of computing and software students from McMaster University in Ontario, Canada, created stunning fractal geometries using the University of Toronto’s powerful IBM Blue Gene/Q supercomputer. Despite being generated by a Read more…

Brain-Inspired Device Simulates One Million Neurons

May 5, 2014 |

Bioengineers at the University of Stanford have developed a new type of circuit board modeled on the human brain. The Neurogrid, as it’s called, operates about 9,000 times faster using significantly less power than a typical PC. While no match for the power and capability of the human brain that inspired it, the new advance Read more…

The Math-Supercomputing Connection

Sep 17, 2013 |

David Brown, the director of the Computational Research Division at Lawrence Berkeley National Laboratory, explores the deep connection between mathematics and modern computer science.

Exascale Advocates Stand on Nuclear Stockpiles

May 23, 2013 |

In quieter times, sounding the bell of funding big science with big systems tends to resonate further than when ears are already burning with sour economic and national security news. For exascale’s future, however, the time could be ripe to instill some sense of urgency….

NSF Forges Further Beyond FLOPs

May 22, 2013 |

In a recent solicitation, the NSF laid out needs for furthering its scientific and engineering infrastructure with new tools to go beyond top performance, Having already delivered systems like Stampede and Blue Waters, they’re turning an eye to solving data-intensive challenges. We spoke with the agency’s Irene Qualters and Barry Schneider about..

Above the Clouds: An Interview with Armando Fox

Aug 2, 2011 |

If you spend any time reading about scientific computing in the clouds, it is quite likely you have encountered the name Armando Fox at least once. Fox has been writing about cloud computing before the term ever emerged into mainstream computing speak and continues to be a prolific source of information about cutting-edge cloud computing research for scientific and technical computing.

On the Grid-Cloud Border at CERN

Oct 12, 2010 |

At the core of the CERN HPC information technology infrastructure is the use of their own internal HPC grid that manages the vast data volumes. Due to the amount of data and complexity of this infrastructure, CERN has created a separate information technology team to handle all aspects of their HPC data volume. According to one of the leaders of this team, CERN’s Sverre Jarp, the facility is “taking steps to move HPC grid infrastructure into the cloud” to better manage this data.
