Heidi Poxon blogs on the Cray site about "Optimizing HPC Program Performance with OpenMP and Reveal". With Reveal you can profile MPI programmes. "Cray Reveal shows you a ranked list of important loops and relevant optimization inhibitors. It lets you browse your source code, get explanations for some of those more confusing optimization messages produced by the compiler, and, with a click of a button, analyzes all of the most relevant loops in your programme and presents parallelization success or failures for your review. Loops are flagged green if no dependencies were found, and Reveal can automatically build and insert OpenMP directives into your source for these loops. A loop is flagged red if Reveal finds issues that require user intervention", Poxon writes. So Reveal can reduce the time it takes to add parallelism to your programme using OpenMP directives.

Focus on Europe

Thousands of British organisations will receive guarantees over EU funding in a new move by Chancellor Philip Hammond of the British Government announced. This includes funding for UK organisations that participate in Horizon 2020 projects. Many advanced e-Infrastructure and supercomputing projects could be affected. This holds for projects that start when the UK is still in the process of exiting the European Union. What happens after that remains unclear. There has been some reluctance of other European organisations to take on board UK partners in European Horizon2020 project proposals. Whether this announcement gives enough reassurance remains to be seen. Apart from the funding of the UK partners, also some contribution for the funding for the overall Horizon 2020 administration seems to be needed. And a lot of legal issues still need to be sorted out. Read further...
