Over at the Cray Blog, David Wallace looks at OpenACC, its programming benefits, and how it is evolving as an industry coalition. OpenACC allows HPC programmers to worry more about the problem they are trying to solve and less about the language and hardware they are using to solve the problem. By enabling parallelism via […]
Today Cray introduced new OpenACC 2.0 support for directives-based programming of accelerators and coprocessors in the company’s supercomputers. Leveraging years of successful production accelerator experience and supercomputing domain knowledge, the Cray OpenACC programming implementation now supports Nvidia Tesla GPU accelerators and Intel Xeon Phi coprocessors on the Cray XC30 series of supercomputers. Congratulations to Cray […]
Today The Portland Group announced that their new PGI Beta release supports OpenACC directive-based accelerator programming for AMD APUs and discrete GPUs. One of PGI’s goals is to increase productivity and provide performance portability for applications developed and maintained by science and engineering domain experts,” said Douglas Miles, Director of The Portland Group. “The OpenACC […]
In this video from the 2013 GPU Technology Conference, Michael Wolfe from The Portland Group demos how OpenACC enables programmers to generate a single binary that runs on Nvidia GPUs and AMD Firepro accelerators.
In this video from SC12, Caps-Enterprise CTO François Bodin describes the company’s tools with support for programming Directives for GPUs, APUs and Intel Xeon Phi using OpenACC.
In this video from SC12, Michael Wolfe from The Portland Group discusses the origins of the OpenACC standard for programming directives in GPUs. He also weighs in on the recent OpenMP 4.0 technical report, which proposes to incorporate OpenACC directives into OpenMP 4.0 sometime in 2013.
This week the The Portland Group announced plans to extend its PGI Accelerator compiler technology with OpenACC to Intel Xeon Phi coprocessors. Using their existing code bases and with only minor modifications to their build scripts, software developers using PGI Accelerator compilers will soon be able to target Intel Xeon Phi coprocessors as well. Until now, […]
The OpenACC standards group has posted a draft of the new OpenACC Version 2.0 specification at the SC12 Conference. With new controls over data movement including better handling of unstructured data, the new version allows for superior performance in parallelizing code and an improved developer experience. OpenACC is an open standard designed to be easy […]
