OpenACC lets you program in parallel C/C++ and Fortran in a manner that is concise and where the same source code can be recompiled to run on AMD GPUs, NVIDIA GPUs, Intel Xeon Phi, x86, and ARM. View at Dr. Dobbs (http://www.drdobbs.com/parallel/easy-gpu-parallelism-with-openacc/240001776) This is the first in a series of articles by Rob Farber on OpenACC directives, … [Read more...]
CUDA 6.0 Released
The CUDA 6 Production Release is now available for download at www.nvidia.com/getcuda. This version of the toolkit includes features that further simplify parallel programming like: • Unified Memory: simplifies programming by enabling applications to access the CPU and GPU memory without the need to manually copy data. • Drop-in Libraries: automatically accelerate … [Read more...]
Part 3 of CUDA Supercomputing for the masses
Error handling and global memory performance limitations. This article is reprinted from Dr. Dobbs (http://www.ddj.com/hpc-high-performance-computing/207603131). It is still valid as an introductory article. Congratulations! Thanks to Part 1 and Part 2 of this series on CUDA (short for "Compute Unified Device Architecture"), you are now a CUDA-enabled programmer with the … [Read more...]
Part 2 of CUDA Supercomputing for the Masses
A first CUDA kernel. Reprinted from Dr. Dobbs April 29, 2008 (link) Comment: This article is still valid as it shows how to write a simple code to move data to/from the GPU and operate on it with a CUDA kernel. In Part 1 of this article series, I presented a simple first CUDA (short for "Compute Unified Device Architecture") program called moveArrays.cu to familiarize … [Read more...]
Farber teaches massively parallel computing to grade 6 – 12 students in Saudi Arabia
My book, “CUDA Application Design and Development” [English][Chinese] and Doctor Dobbs tutorials coupled with the rapid adoption of GPU computing have given me the opportunity to speak and teach around the world. This January, I had the pleasure of traveling to Jeddah, Saudi Arabia to speak and teach a short course on OpenACC and CUDA at KAUST (the King Abdullah University of … [Read more...]
