Applications

ETP4HPC organises a workshop on (pre)-exascale demonstrators in Frankfurt on June 22. This meeting will provide insight into the extreme scale demonstrator concept and its setup, and allow interested industrial HPC users and ISVs to express needs and expectations regarding the potential use of extreme scale demonstrators.

On the EPCC blog Nick Johnson explains some tricks to speed up Python on the ARCHER supercomputer. He is concentrating on a Marine tech project by the London Firedrake team. Running on ARCHER, it scales well in the computation phase, but not well at start-up. "Why?", Nick Johnson asks. At start-up, the Python interpreter parses its paths and loads a default set of modules, each accessing the same files. On 1000 nodes, this takes about 45 minutes for the 24,000 Python interpreters to go through this routine. Read further...
In his latest blog post "Balancing act: optimise for scaling or efficiency?" on the EPCC site, Adrian Jackson writes about choices to make when optimising parallel applications especially when preparing for exascale. There are many unknowns so it is hard to make correct choices at this moment. Read further...

Focus on Europe

This year the Latin American Conference on High Performance Computing (CARLA 2017) will be held in Buenos Aires, from September 20 to September 22. The main goal of CARLA 2017 is to provide a regional forum fostering the growth of the HPC community in Latin America through the exchange and dissemination of new ideas, techniques, and research in HPC.
