Commercial OpenCL! SPIR 2.0 Protects IP Yet Allows Powerful, Portable, Source Code Free Kernels
It used to be that portable OpenCL applications required shipping source code for the parallel kernels with the application. In this way, the kernel source code could be compiled for any device at any time in the future. Bad news from an IP protection point of view! The alternative was to pre-compile the kernels thus bloating applications and limiting the devices the OpenCL … [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...]
