For many embedded applications power consumption is king. System On a Chip (SOC) designs such as the ARM-based Altera Cyclone V development board provides a Linux-based environment to program and run parallel applications on an FPGA using OpenCL much like the well-known NVIDIA Jetson development board. What a wonderful opportunity to compare the performance and power … [Read more...]

Firefox WebCL plugin, WebCL Security, and Compliance Tests
Interest in WebCL is expanding as exemplified by the Nokia WebCL project that has released a Firefox plugin to run WebCL apps. Developers now have a choice of running WebCL in Chrome via AMD and Firefox with the Nokia plugin. (Firefox, Chrome and Safari all have some form of WebCL support.) The continued expansion of WebCL proof-of-concept … [Read more...]
The Missing Link in NVlink, or “Hello Pascal” bye-bye PCI bus limitations!
Say hello to NVlink, a new technology by NVIDIA that is not constrained by PCIe bandwidth and latency limitations, but you will have to wait for the Pascal generation of 2016 GPUs to get it. NVlink is NVIDIA's properitary "DRAM speed and latency" class interface for CPU to GPU and GPU to GPU point-to-point communications. The basic building block for NVLink is a high-speed, … [Read more...]
OpenCL Haswell Iris 5200 Performance Results – 800 GF/s Peak Performance
The Intel Haswell chip contains an integrated GPU that delivers significantly better OpenCL performance than an NVIDIA GeForce GT 650M - exceeding 800 GF/s peak performance. Allan MacKinnon at PixelIO has been investigating the OpenCL performance of this device and has been finding a plethora of on-gpu registers but also that the GPU appears to be both power and thermally … [Read more...]
OpenCL + Java Acceleration on Mobile Promises 8x speedup with 3x Less Power
In what will certainly become a flood of papers about GPU acceleration of Java applications on mobile devices, a masters theses by Iype P. Joseph at the University of Ottawa claims 8x performance gains and 3x reductions in power consumption through the use of Java binding with OpenCL 1.1 on a a Freescale i.MX6Q SabreLite board. With NVIDIA entering the programmable mobile GPU … [Read more...]
