NVIDIA Takes PGI Under Wing

Jul 29, 2013 |

Moments ago, NVIDIA announced its acquisition of the Portland Group (PGI) which has provided compiler and tools for the HPC-oriented C and Fortran markets. According to the company’s Sumit Gupta, this will allow them to further build their software portfolio and to push the adoption of GPUs through OpenACC in particular. NVIDIA and PGI will…

Lustre Founder Spots Haskell on HPC Horizon

Jun 24, 2013 |

According to Lustre founder and current CEO of Parallel Scientific, languages that buck the mainstream trend, including Haskell, could find further inroads into HPC as models, data sizes and overall complexity grow. We spoke with Braam at ISC and discovered that like Python, there are…

Exterminating at Extreme Scale

May 7, 2013 |

Since the first bug was eradicated from a Mark II system at Harvard in 1940s (an actual moth wedged in a relay, which drove the machine to a standstill) system exterminators have faced a constant spray of challenges. We talk with Allinea co-founder David Lecomber about challenges on Titan and Blue Waters–and the future of debugging exascale …

Unleashing The Potential of OpenMP via Bottleneck Analysis

Feb 13, 2014 |

To capitalize on the computational potential of parallel processors, programmers must identify bottlenecks that limit their application. These bottlenecks typically chain performance preventing an application from reaching its full potential. Performance analysis typically provides the data and insight necessary to identify opportunities for program optimization. Researchers in the Inderprastha Engineering College identify general bottlenecks for Read more…

Scientific Computing: the Case for Python

Jan 10, 2014 |

What’s in your scientific computing toolbox? Over at the R Bloggers site, University of Texas at Austin research associate Tal Yarkoni explains why these days, his go-to language is Python, whether it’s for text processing, numerical computing, or even data visualization. The post, subtitled “why Python is steadily eating other languages’ lunch,” explores the advantages Read more…

Consortium Advances Spatial Computing Standard

Dec 10, 2013 |

A new programming standard, called the Open Spatial Programming Language (or OpenSPL), debuted today “to enable the next generation of high performance parallel spatial computers.” The open standard was developed by the Open Spatial Programming Language (OpenSPL) consortium, which formed to promote the use of spatial computing among a wide set of users and to Read more…

Wolfram CEO Advances ‘A New Level of Computation’

Nov 27, 2013 |

Wolfram Research Founder and CEO Stephen Wolfram believes in the power of computation to shape the world. The company’s goal is to provide the framework to enable computation to reach its full potential in the coming decades. Facilitating this goal means making it possible to compute “whatever can be computed, whenever it is needed.” Earlier Read more…

Opening Up the Accelerator Advantage

Nov 26, 2013 |

Researchers at Georgia Institute of Technology and University of Southern California will receive nearly $2 million in federal funding for the creation of tools that will help developers exploit hardware accelerators in a cost-effective and power-efficient manner. The purpose of this three-year NSF grant is to bring formerly niche supercomputing capabilities into the hands of Read more…
