Shared Memory is Simple on Intel Xeon Phi – supports STL!
Shared memory on Intel Xeon Phi, in OpenCL, and CUDA (via managed memory) greatly simplifies programming by eliminating the need to explicitly define all data transfers between host and device memory. Once these implementations mature, it is likely they will become the standard API that programmers use to access data on both Intel Xeon Phi and GPUs. (They also naturally support … [Read more...]
Intel SPMD Compiler (ISPC) for Xeon and Xeon Phi
When #pragma SIMD is not enough, companies and projects such as Intel, Embree, Dreamworks, Pixar, Autodesk, and SURFsara are looking to the freely available Intel SPMD Program Compiler (ispc) to achieve high vector performance on Xeon and Intel Xeon Phi devices. ISPC is LLVM-based and designed to exploit Intel SIMD architectures … [Read more...]
A Try-Before-You-Code Linear Regression Method Claims 32% Error Predicting GPU Perf
The paper, "Estimating GPU Speedups for Programs Without Writing a Single Line of GPU Code" by Newsha Ardalani, Karthikeyan Sankaralingam, Xiaojin Zhu at the University of Wisconsin Madison claims a linear regression model can deliver a robust "automated tool that programmers can use to estimate potential GPU speedup before writing any GPU code". According to their study a … [Read more...]
Bringing “Getting-by” Girls into Science and Technology
Recent gender diversity reports from Google, Facebook, and Apple (to name a few) have spurred a number of positive efforts to bring more women into computer science including the Supercomputing 2014 (SC14 WHPC) “Women in High Performance Computing” workshop, NVIDIA’s “Women who CUDA” campaign, and Google’s $50M “Women Who Code” program. The severely biased percentages for tech … [Read more...]
PyFR: A GPU-Accelerated Next-Generation Computational Fluid Dynamics Python Framework
PyFR is an open-source 5,000 line Python based framework for solving fluid-flow problems that can exploit many-core computing hardware such as GPUs! Computational simulation of fluid flow, often referred to as Computational Fluid Dynamics (CFD), plays an critical role in the aerodynamic design of numerous complex systems, including aircraft, F1 racing cars, and wind turbines. … [Read more...]
Army and Census Bureau Calls
The census bureau is entering the big data arena (link) and is looking for a published expert who can host conferences and provide "the best advice to guide a national statistical agency on ways to use big data to solve specific problems." The army has released a large solicitation focused on night vision technologies. There are numerous topics, some of which would benefit … [Read more...]
