Chromebooks can now run Linux without dual-booting via Crouton (ChRomium Os Universal chrooT envirONment)! A big advantage of Crouton is that users don't have to reboot their machine to switch operating systems. Moving to Linux can be as simple as using a keyboard shortcut. Crouton can be downloaded from github (). Crouton is a set of scripts that act as an easy-to-use, … [Read more...]
Facebook Open Source GPU FFT 1.5x Faster Than NVIDIA CUFFT
Facebook has written a Fast Fourier Transform (fbfft) that is 1.5x faster than the NVIDIA CUFFT implementation at sizes 8-64. The paper "Fast Convolutional Nets with fbfft: A GPU Performance Evaluation" discusses the performance increases by changing to a non-zero padded FFT layout (potentially eliminating data copies), the use of autotuning, and clipping to conditionally load … [Read more...]
ORNL Introductory Tutorials On Concurrent Kernels
The OLCF at Oakridge National Laboratory (ORNL) is working to educate users about how to best use their computing resources. As part of that process, the OLCF has published two very introductory tutorials to teach how to utilize concurrent kernels on their systems. Part 1 (concurrent kernels) and Part 2 (batched library calls) teach how to launch concurrent kernels using CUDA … [Read more...]
Computational Method Accurately Predicts Pressure-Dependent Combustion Chemical Reactions
A featured paper in the December 5th 2014 issue of Science demonstrates - for the first time - a computational method to successfully a priori predict pressure-dependent chemical reaction rates. In short, this work provides an accurate means of treating pressure dependence, which is required to accurately predict the aggregate reaction rate. Unlike previous models that rely on … [Read more...]
Implications of OS Jitter on Real-Time Applications for FPGAs, GPUs, and Intel
FPGAs, GPUs, and Intel Xeon Phi coprocessors can all offer superb performance at low watt/flop and high flop/dollar ratios for real-time computing. To promote real-time FPGA development, several Altera Engineers (Chee Nouk Phoon,Chei Siang Ng, Steve Jahnke, plus Findlay Shearer, Linux Marketing Manager) examined the impact of operating system jitter on real-time performance in … [Read more...]

HOPE is published under the GPLv3 license. It can be downloaded from it's GitHub repository. It was written by Joel Akeret, Lukas Gamper, … [Read more...]
Trend – Web And Big-Box Retailers the Future of Primary Medical Care
To reduce costs, a number of health organizations like Kaiser-Permanente, Bellin Health, PinnicleHealth, QualMed, and others are teaming with big-box retailers like Target, Safeway, Giant and other big-box retailers to create in-store medical clinics for primary care. The model is web-based where nurses and nurse practitioners staff the in-store location to screen patients. If … [Read more...]
IPMACC – An Open Source OpenACC to CUDA/OpenCL Translator
IPMACC is a research-grade open-source framework for translating OpenACC source code to CUDA or OpenCL. Binary executables can then be created with OpenCL or CUDA compilers. The authors (Ahmad Lashgar - University of Victoria, Alireza Majidi - Texas A&M University, Amirali Baniasadi - University of Victoria) verified correctness and performance using benchmarks from … [Read more...]
