MeerKAT Telescope Reveals New Details of Universe

Jul 20, 2016 |

This week, the world saw the first images captured by the MeerKat array, which made its debut as one of the most powerful telescopes of its kind. Using 16 out of a planned 64 dishes, the telescope array recorded the radio signals coming from a small area of sky comprising less than .01 percent of Read more…

COSMOS Team Achieves 100x Speedup on Cosmology Code

Aug 24, 2015 |

One of the most popular sessions at the Intel Developer Forum last week in San Francisco, and certainly one of the most exciting from an HPC perspective, brought together two of the world’s foremost experts in parallel programming to discuss current state-of-the-art methods for leveraging parallelism on processors and coprocessors. The speakers, Intel’s Jim Jeffers and Read more…

Astronomical Supercomputer Crosses Petascale Divide

Dec 2, 2014 |

One of the biggest benefits of the inexorable push toward exascale computing is a coming age of more affordable petascale systems. This trend can already be seen as science centers around the world crest this important barrier. One of the latest to do so is the Center for Computational Astrophysics (CfCA) of the National Astronomical Observatory of Japan (NAOJ), which Read more…

Supercomputers Help Capture Rare Black Hole Events

Apr 16, 2014 |

When an orbiting star gets too close to a galaxy’s central supermassive black hole, it eventually gets torn apart by the immense gravitational forces, a phenomenon known as a “tidal disruption.” Although black holes cannot be seen directly, since their dense mass means that not even light can escape, the inhaled star produces a brief Read more…

Heavy Metal Shapes Early Cosmos

Feb 7, 2014 |

Astronomers at the University of Texas have made a series of remarkable discoveries using some of the most powerful supercomputers in existence. Massive numerical …

Supercomputing Fundamental to SKA Project

Dec 12, 2013 |

First proposed in 1991, the Square-Kilometer Array (SKA) project seeks to build and operate the largest radio telescope in the world to peer into the deepest recesses of the cosmos. Instead of seeing light waves, the SKA telescope will turn radio waves into images. The array will be 50 times more sensitive than any other Read more…

A One-of-a-Kind Supercomputer to Map the Cosmos

Jan 9, 2013 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/ALMA_supercomputer_small.jpg” alt=”” width=”97″ height=”79″ />A new petascale supercomputer built to study the universe is one of the fastest calculating machines in the world, and certainly the fastest of its kind. The supercomputer is part of ALMA, a new radio telescope that is claimed to be “largest ground-based astronomical project in existence.”

Astronomers Look to Exascale Computing to Uncover Mysteries of the Universe

Apr 3, 2012 |

When brought online, the Square Kilometer Array radio telescope will generate an exabyte of data every day.

Canada Explores New Frontiers in Astroinformatics

Jan 17, 2011 |

The number of scientific instruments available to astronomy researchers for gathering data has grown significantly in recent years, leading to unprecedented amounts of information that requires vast storage and processing capabilities. Canadian researchers are finding a way around this problem with a new solution that combines the best of grid and cloud computing, allowing them to more efficiently reach their research goals.

TeraGrid 2010 Keynote: The Physics of Black Holes with Cactus

Aug 11, 2010 |

TeraGrid ’10, the fourth annual conference of the TeraGrid, took place last week in Pittsburgh, Pa. HPCwire will be running a series of articles highlighting the conference. The first in the series covers Gabrielle Allen’s keynote talk on Cactus, an open, collaborative software framework for numerical relativity.
