Contrary View: CPUs Sometimes Best for Big Data Visualization

Dec 1, 2015 |

Contrary to conventional thinking, GPUs are often not the best vehicles for big data visualization. In this commentary, I discuss several key technical reasons why a CPU-based “Software Defined Visualization” approach can deliver a more flexible, performant, scalable, cost effective, and power efficient solution to big data visualization than a conventional GPU-based approach. An example Read more…

If you need a reason to join the Periscope craze, how about getting an inside look at the fastest supercomputer in the United States? Today staff at the Oak Ridge Leadership Computing Facility (OLCF), the DOE Office of Science user facility at Oak Ridge National Laboratory (ORNL) took the Periscope audience on a tour of Titan, Read more…

PGI Accelerator Compilers Add OpenACC Support for x86 Multicore CPUs

Oct 29, 2015 |

NVIDIA today announced availability of its newest PGI Accelerator Fortran, C and C++ compilers (version 15.10) now with support for OpenACC directives-based parallel programming standard on x86 architecture multicore microprocessors. The new compilers allow OpenACC-enabled source code to be compiled for parallel execution on a multicore CPU or a GPU accelerator. “Our goal is to Read more…

Filippo Mantovani on What’s Next for Mont-Blanc and ARM

Jul 6, 2015 |

Firing up the Mont-Blanc prototype in mid-June at the Barcelona Supercomputing Center (BSC) was a significant milestone in the European effort to base HPC systems on energy efficient architecture.

Is IBM Getting Openness Right? Yes, Says GM Doug Balog

Jun 29, 2015 |

The annual Red Hat Summit, held in Boston last week, is something of revival tent for open source where the pulpits are plentiful and so are smiling believers. Indeed it’s hard to dispute the powerful innovation springing from open source. The RH Summit, which started 11 years ago as a modest celebration of open source Read more…

IBM Power8 Outperforms x86 on Financial Benchmarks

Jun 9, 2015 |

If you’ve been waiting for a formal evaluation of the IBM Power8 architecture on common financial workloads, then look no further. According to results shared at the STAC Summit on June 4, an IBM Power8-based system server delivered more than twice the performance of the best-in-class x86 counterpart when running a set of standard financial industry benchmarks. Sumit Read more…

CPU Benchmarking: Haswell Versus POWER8

Jun 2, 2015 |

With OpenPOWER activity ramping up and IBM’s prominent role in the upcoming DOE machines Summit and Sierra, it’s a good time to look at how the IBM POWER CPU stacks up against the x86 Xeon Haswell CPU from Intel. Citing the compute-intensive nature of today’s financial applications, the acceleration specialists at Xcelerit sought to compare IBM’s powerhouse Read more…
