PathScale is capitalizing on over six years of development with the release of ENZO 2015, a compiler suite that allows C/C++/Fortran parallel programs to be built for a variety of hardware platforms from a single OpenACC or OpenMP4 source base. The PathScale compilers can generate executables for AMD GPUs, and NVIDIA GPUs as well as ARMv8 and x86 instruction sets. As a result, … [Read more...]
GCC5 Release Candidate in Early April With OpenACC, Cilk, and OpenMP4 Offload!
Richard Biener posted a message to gcc.gnu.org to expect a GCC 5 release candidate the first week of April. GCC5 supports OpenACC, Cilk Plus, and OpenMP 4.0 offload support. "We've come a long way towards the release criteria of zero P1 bugs. There are still a few remaining P1s though and we are targeting for a GCC 5 release candidate in the first week of April (given those … [Read more...]
Concise Comparision Adds OpenMP Versus OpenACC To CUDA Versus OpenCL Debates
The debate over OpenMP versus OpenACC for manycore and heterogeneous computing is starting to heat up. Michael Wong (CEO of OpenMP Corp), Barbara Chapman (Univ. Houston), and Yonghong Yan (Assistant Prof. Univ. Oakland and OpenMP ARB representative) have written a nice, quick read, comparative article on HPCWire: "A Comparison of Heterogeneous and Manycore Programming … [Read more...]
Profiling Guided Optimization On Intel Xeon Phi
This chapter in High Performance Parallelism Pearls by Andrey Vladimirov focuses on the use of Intel VTune Amplifier XE reports to understand where to apply optimization on matrix transposition, a small and self-contained workload of great practical value. The optimization process applied to the code relies exclusively on programming in a high-level language plus utilization of … [Read more...]

Paper Compares AMD, NVIDIA, Intel Xeon Phi CFD Turbulent Flow Mesh Performance Using OpenMP and OpenCL
Timely for Siggraph 2014 (because animations use meshes) and food-for-thought for CFD (Computational Fluid Dynamics) research, the paper by A. Gorobets, F.X. Trias, R. Borrell, G. Oyarzún and A. Oliva, "Direct Numerical Simulation of Turbulent Flows with Parallel Algorithms for Various Computing Architectures" considers structured and unstructured meshes for incompressible … [Read more...]
Hot At Siggraph 2014 – Multithreading for Visual Effects
The ACM Siggraph conference starts tomorrow, August 10th, in Vancouver, BC. Multithreading for visual effects coupled with massive parallelism has changed the visual effects industry forever. A new book capturing that trend titled, appropriately enough, "Multithreading for Visual Effects", is an excellent source of information about how visual effects are currently performed at … [Read more...]
