Building Parallel Code with Hybrid Fortran

Jul 31, 2014 |

Over at the Typhoon Computing blog, Michel Müller addresses a topic that is top of mind to many HPC programmers: porting code to accelerators. Fortran programmers porting their code to GPGPUs (general purpose graphics processing units) have a new tool at their disposal, called Hybrid Fortran. Müller shows how this open source framework can enhance portability without sacrificing performance and maintainability. From the blog (editor’s note: the site Read more…

Programmability Matters

Jun 30, 2014 |

While discussions of HPC architectures have long centered on performance gains, that is not the only measure of success, according to Petteri Laakso of Vector Fabrics. Spurred by ever-proliferating core counts, programmability is taking on new prominence. Vector Fabrics is a Netherlands-based company that specializes in multicore software parallelization tools, so programmability is high on Read more…

Should I Buy GPGPUs or Blue Gene?

Nov 4, 2010 |

Given the recent ascent of the GPU-powered Tianhe-1A system to the top of the supercomputing heap, a current paper from Department of Computer Science at the University of Warwick should be of particular interest to those in the market for a petascale supercomputer. Essentially their study asks the question: As an organization, should I commit to a platform based on general-purpose GPUs or an IBM Blue Gene?
