Today the ARCHER national supercomputing service in the U.K. announced that it has deployed the Allinea MAP profiling tool to enable computational scientists and developers to tackle scalability and performance in key scientific applications that run on their 2.5 Petaflop Cray XC30 system.

Video: Intro to Compiler Directives for Accelerators

openACC

“Geoscientists need tools to allow them to rapidly develop algorithms that run fast on accelerators, while at the same time deliver portability and improve productivity. They demand a single source code, with no need to maintain multiple code paths, using a high-level approach that presents a low learning curve. OpenACC provides directives-based approaches to rapidly accelerating applications for GPUs and other parallel architectures. This talk will serve as an introduction to programming with OpenACC 2.0.”
