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…

The New Breed of Accelerators from NVIDIA, Intel and AMD Square Off

Dec 6, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Xeon_Phi_chip_small.jpg” alt=”” width=”96″ height=”79″ />With the recent introduction of Intel’s first Xeon Phi coprocessors, NVIDIA’s latest Kepler GPUs, and AMD’s new FirePro S10000 graphics cards, the competition for HPC chip componentry has entered a new phase. The three chipmakers have taken somewhat different paths, though, and it will be up to the market to decide which vendor’s approach will win the day.
