Evolving Exascale Applications Via Graphs

Apr 29, 2014 |

There is little point to building expensive exaflop-class computing machines if applications are not available to exploit the tremendous scale and parallelism. Consider that exaflop-class supercomputers will exhibit billion-way parallelism, and that calculations will be restricted by energy consumption, heat generation, and data movement. This level of complexity is sufficient to stymy application development, which Read more…

Samplify Puts the Squeeze on Compression

Jun 27, 2013 |

In advance of a presentation last week at the International Supercomputing Conference in Leipzig, Germany we spoke with Samplify, which offered up insights on how lossy compression isn’t the scary prospect that it may seem to be for application areas that require high-fideltiy and long-term storage of datasets. Climate studies and…

Alternatives Emerge as Linpack Loses Ground

Jun 18, 2013 |

Today at the International Supercomputing Conference in Leipzing, Germany, Jack Dongarra presented on a proposed benchmark that could carry a bit more weight than its older Linpack companion. The high performance conjugate gradient (HPCG) concept takes into account new architectures for new applications, while shedding the floating point….

DOE Commissions Extreme Computing Study

Dec 3, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Compete_logo_2012.jpg” alt=”” width=”92″ height=”92″ />The Council on Competitiveness has been awarded a $914,000 grant from the Department of Energy to explore the implications of the emerging post-petaflop era and the challenges associated with extreme computing. HPCwire talks to Council on Competitiveness Senior Vice President Cynthia R. McIntyre to learn more about the project.

The Future of Workload Management

Oct 12, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/venn_diagram_colors_200x.jpg” alt=”” width=”98″ height=”78″ />In this era of heterogeneous architectures and hybrid infrastructures, workload managers are necessarily becoming more and more sophisticated. Looking toward the future of workload management, there are three major trends: application insight, big data awareness, and HPC clouds. While inter-related, each has something important to contribute to the advancement of HPC.

Despite the red curtain, China’s cloud computing aspirations are no secret.

The New Era of Intelligent Application Mobility

Jul 19, 2011 |

Duncan Johnston-Watt, founder & CEO of Cloudsoft describes the concept of intelligent application mobility and the new possibilities this signals via the ability to seamlessly move applications across clouds and locations.

Cloud@Home: Goals, Challenges and Benefits of a Volunteer Cloud

Mar 17, 2011 |

Building on ideas from grid computing, Dr. Salvatore Distefano and Dr. Antonio Puliafito discuss the concept of volunteer computing via Cloud@Home. This could be a way for implementing ubiquitous and pervasive computing as many computational devices and systems can be engaged simultaneously for performing ordinary activities, and may not necessarily be aware that they are doing so.

Emerging Services Extend Public Cloud Portability

Mar 4, 2011 |

Once applications are up and running on public clouds, it is difficult to move them over to another cloud. Some services are trying to help manage migration ability to allow greater portability and thus more options.
