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…

Defining Scalable OS Requirements for Exascale and Beyond

Oct 5, 2015 |

Over the past couple of decades two primary trends have driven system software for supercomputers to become significantly more complex. First, hardware has become more complex. Massive inter-node parallelism (100,000+ nodes), increasingly large intra-node parallelism (100+ hardware threads), wider vector units, accelerators, coprocessors, etc., have required that system software play a larger role in delivering Read more…
