CARP project targets its output to OpenCL

December 2011 saw the kick-off of an ambitious research project called “CARP: Correct and Efficient Accelerator Programming”, which aims to boost the programmability of accelerator hardware, such as graphics processing units (GPUs), by innovating in programming language design and implementation, as well as formal verification techniques. Funded by the European Commission’s Seventh Framework Programme (FP7), the consortium, which consists of eight partners--including Khronos members ARM, Imperial College London and Rightware--seeks to provide a unified flow for developing correct and efficient accelerator software, thus increasing reliability and energy efficiency of computing systems.

Vivante leads mobile GPGPU revolution as first GPU IP supplier to pass OpenCL 1.1 conformance test

Vivante Corporation today announced Vivante GC Cores passed the Khronos Group OpenCL 1.1 Embedded Profile (EP) conformance test suite on Freescale's i.MX 6 platform. The GC Cores use the latest programmable ScalarMorphic architecture to accelerate parallel data workloads on thousands of concurrent threads to achieve Gigaflops (GFLOPS) of computational performance. Applications taking advantage of Vivante cores to significantly speed-up processing includes image processing, computer vision, analytics, augmented reality and gesture-motion tracking.

Imagination makes the case for mobile OpenCL

Imagination was showing off GPU compute on a cell phone chip at GDC, physics in your pocket. That demo was pretty simple, take a Pandaboard with a TI OMAP 4430, a dual-core ARM A9 CPU and an Imagination SGX540 GPU, and run a cloth simulation on it. Not only could the OpenCL version exploit the GPU to do more balls and sheets than the CPU version, but it saved power while doing so. How much? On one CPU, the simulation took about .68A@5V to run at 14FPS with 100% CPU load. With two A9 cores loaded, the Pandaboard pulled .84A and ran at 24FPS. In OpenCL, CPU load dropped to less than 30%, FPS jumped to 42, and power draw went down to .60A. More than 10% less energy used, 3x the frame rate, and you could run more simulations on the same box if you wanted. Not bad at all.
