Intel Xeon Phi for CUDA Programmers
Both GPU and Xeon Phi coprocessors provide high degrees of parallelism that can deliver excellent application performance. For the most part, CUDA programmers with existing application code have already written their software so it can run well on Phi coprocessors. The key to performance lies in understanding the differences between these two architectures. Author's note: To … [Read more...]

Pick the Right WordPress Hosting
Updated July 2, 2016 (thanks to Paul Warren of Insiteful) WordPress is a free and open-source blogging tool and Content Management System (CMS). It was released on May 2003. According to Wikipedia, WordPress now powers more than 26.4% of the top 10 million websites as of April 2016. This represents significant growth as Wikipedia previously noted WordPress was used by 18.9% of … [Read more...]
HPC Balance and Common Sense
Key concepts for any procurement, system design, or system analysis are presented in my 2007 Scientific Computing article ( link ). A common sense approach is to keep what works and improve on what doesn’t. In other words, measure the performance characteristics of your current system(s) and keep those characteristics that support your workloads and improve on any that might … [Read more...]
Programming Intel’s Xeon Phi: A Jumpstart Introduction
Reaching one teraflop on Intel's new 60-core coprocessor requires a little know-how First printed December 10, 2012 on Dr. Dobbs ( link ) Developers can reach a teraflop/s of number crunching power via one of several routes: Using pragmas to augment existing codes so they offload work from the host processor to the Intel Xeon Phi coprocessors(s) Recompiling source … [Read more...]
Part 1: OpenCL™ – Portable Parallelism
This first article in a series on portable multithreaded programming using OpenCL™ briefly discusses the thought behind the standard and demonstrates how to download and use the ATI Stream software development kit (SDK) to build and run an OpenCL program. view at The Code Project (http://www.codeproject.com/Articles/110685/Part-OpenCL-Portable-Parallelism) The thought … [Read more...]
