New PyFR Paper “Heterogeneous Computing on Mixed Unstructured Grids with PyFR”
Peter Vincent's original PyFR post on TechEnablement has been extremely popular. Readers should be happy to hear that the PyFR team has published a new paper, "Heterogeneous Computing on Mixed Unstructured Grids with PyFR", showing this Python framework can perform high-order accurate unsteady simulations of flow on mixed unstructured grids using heterogeneous multi-node … [Read more...]
OpenACC Compilers Deliver 85% The Performance Of Hand-Optimized Code
Directive-based compilers offer both portability and the ability to optimized code for specific platforms such as GPUs and CPUs. A recent LCPC14 paper, "Directive-Based Compilers for GPUs", by Swapnil Ghike, Ruben Gran, Maria J. Garzaran, David Padua at the University of Illinois at Urbana-Champaign found OpenACC code generated by the PGI and Cray OpenACC compilers achieved … [Read more...]
Mix OpenACC and CUDA (including Thrust)

CUDA 340.29 Driver Significantly Boosts GPU Performance (100s GF/s For Machine-Learning)
Reports are now coming in about performance boosts that are the result of the CUDA 6.5 production release. The Blender project reports faster rendering time with CUDA-6.5. As can be seen in the graphs below that report performance on the farbopt deep-learning teaching code, CUDA-6.5 with the NVIDIA 340.29 driver have increased performance on linear problems (PCA analysis from … [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...]
