Dust Storms Put GPU CPU Performance to the Test

Jun 6, 2013 |

A team of researchers modeling environmental events looked to the relative efficiencies of using GPU and CPU approaches for their processing and rendering. While CPUs were needed due to limited on-board GPU memory….

Amazon EC2 Versus the Competition

Nov 6, 2012 |

New report compares Amazon EC2 with nine other IaaS providers on a range of performance and stability metrics.

InfiniBand-Backed Cloud Provider Goes Toe-to-Toe with Amazon, Rackspace

Sep 13, 2012 |

IaaS provider ProfitBricks proclaims noteworthy performance-metrics, pits service against the top two cloud providers.

Latency in the Cloud – How Low Can We Go?

Jun 26, 2012 |

At the HPC Advisory Council European Conference 2012 in Hamburg, in conjunction with the International Supercomputing Conference (ISC’12), VMware’s HPC guru Josh Simons delivered a presentation of particular interest to followers of the HPC cloud space. The session tackled the million dollar HPC cloud question: “Are cloud computing and virtualization only useful for running throughput workloads or can latency-sensitive applications be run as well?”

Panasas Backfills ActiveStor Lineup

Jun 23, 2011 |

High performance parallel storage vendor Panasas is eyeing the technical computing and big data markets with the release of its ActiveStore 11 parallel storage system appliance, a step back from 12 that comes with a more balanced storage profile and lower price per terabyte than the performance-driven ActiveStor 12.

Startup Cooks Up Software Sauce for SSDs

Jun 7, 2011 |

VeloBit, which emerged from stealth today following an undisclosed round of funding, is talking up its soon-to-launch software cure for SSD performance ills. Although their product won’t appear until later in the year, they claim their solution packs an order of magnitude price-performance improvement for solid-state drives.

Compilers and More: Exascale Programming Requirements

Apr 14, 2011 |

In his third column on programming for exascale systems, Michael Wolfe shares his views on what programming at the exascale level is likely to require, and how we can get there from where we are today. He explains that it will take some work, but it’s not a wholesale rewrite of 50 years of high performance expertise.

Compilers and More: Expose, Express, Exploit

Mar 28, 2011 |

In Michael Wolfe’s second column on programming for exascale systems, he underscores the importance of exposing parallelism at all levels of design, either explicitly in the program, or implicitly within the compiler. Wolfe calls on developers to express this parallelism, in a language and in the generated code, and to exploit the parallelism, efficiently and effectively, at runtime on the target machine. He reminds the community that the only reason to pursue parallelism is for higher performance.

Reid Smith from Savvis on Delivering High Performance Clouds

Nov 3, 2010 |

This week at Cloud Expo I spent some time talking to Reid Smith from Savvis about the range of cloud services and the role networks play within them for enterprise customers outside of financial services where low latency is not the top priority. We also touched on what makes clouds high performance and attractive to a range of potential users.

Say Hello to the New ADIOS

Sep 12, 2010 |

Last week marked the release of ADIOS 1.2, the latest incarnation of one of computational science’s most effective I/O tools. So far ADIOS has helped researchers make huge strides in fusion, astrophysics and combustion. The new version features some interesting improvements that will doubtless aid researchers in taking full advantage of leading supercomputing platforms.
