NVIDIA Enables New Video Processing, I/O Capability for Quadro and Tesla GPUs with OpenCL and CUDA

At the International Broadcasting Convention 2011NVIDIA introduced NVIDIA GPUDirect for Video. This technology enables application developers to deliver higher quality, more realistic on-air graphics -- or take faster advantage of the parallel processing power of the GPU for image processing. This is done by permitting industry-standard video I/O devices to communicate directly with NVIDIA professional Quadro and Tesla graphics processing units (GPUs) at ultra-low latency. Nick Rashby, President, AJA Video Systems says "this will allow developers whose apps support AJA video I/O products to take better advantage of the power of NVIDIA Quadro and Tesla GPUs, resulting in low-latency access for both graphics compositing and general purpose processing using CUDA or OpenCL, with all the I/O and performance they depend on from AJA."

Harlan targets complexity for GPGPU programming and compiles to OpenCL

HPC programmers who are tired of managing low-level details when using OpenCL or CUDA to write general purpose applications for GPUs (GPGPU) may be interested in Harlan, a new declarative programming language designed to mask the complexity and eliminate errors common in GPGPU application development. The idea with Harlan is to keep developers focused on the high-level HPC programming challenge at hand, instead of getting bogged down with the nitty gritty details of GPU development and optimization. Harlan's syntax is based on the language Scheme, and compiles to Khronos Group's OpenCL.
