ORNL Introductory Tutorials On Concurrent Kernels
The OLCF at Oakridge National Laboratory (ORNL) is working to educate users about how to best use their computing resources. As part of that process, the OLCF has published two very introductory tutorials to teach how to utilize concurrent kernels on their systems. Part 1 (concurrent kernels) and Part 2 (batched library calls) teach how to launch concurrent kernels using CUDA … [Read more...]
IPMACC – An Open Source OpenACC to CUDA/OpenCL Translator
IPMACC is a research-grade open-source framework for translating OpenACC source code to CUDA or OpenCL. Binary executables can then be created with OpenCL or CUDA compilers. The authors (Ahmad Lashgar - University of Victoria, Alireza Majidi - Texas A&M University, Amirali Baniasadi - University of Victoria) verified correctness and performance using benchmarks from … [Read more...]

MultiOS Gaming, Media, and OpenCL Using XenGT Virtual Machines On Shared Intel GPUs
At last, a full (opensource!) GPU virtualization solution that allows virtualized guest operating systems to "own" a shared Intel GPU yet allows applications to run with near-native performance! This means games, both DRM and free media, plus OpenCL applications can run in separate guest operating systems on a single Intel GPU system (convenient for users) or in a shared cloud … [Read more...]
AMD and Pathscale Join OpenACC Standards Committee
AMD and Pathscale announced at SC14 that they have joined the OpenACC standards committee. OpenACC provides an efficient and performance-portable path for developing massively parallel programs across a wide range of accelerators, including GPUs, many core coprocessors and multi-core CPUs. OpenACC has been gaining traction for parallel programming. Such a move appears … [Read more...]
