Applications of computing underpin all aspects of our lives. It is a cornerstone of academia and industry where everything, from fundamental physics and climate research to self-driving cars and financial trading, depends on algorithms to deliver solutions that are accurate, fast, safe and cheap. Data is driving a scientific revolution that relies heavily on computing to process, analyse, and translate information into knowledge and technological innovations.
Simultaneously, computing is undergoing a tectonic change with the end of Moore's law for hardware and extensive deployment of accelerator technologies where traditional modelling is increasingly complemented by data-driven approaches and artificial intelligence. We are witnessing a revolution in humankind's ability to solve complex problems by relying on the synergy of advanced algorithms, data, and hardware. The US, China and Japan are making great strides in these frontiers, and PRACE calls attention to the urgent need for an expanded European advanced computing infrastructure to cover a broad range of applications, education and workforce training.
European researchers are leading in algorithm and software development in many fields, which has helped create a thriving computational community. However, the present infrastructure's compute capacity, as well as insufficient investments in algorithms and software, are currently the major bottlenecks to European leadership, applications and industrial impact. Moreover, enhanced synergies between scientists working on hardware, algorithms, and applications is required for advancing the frontiers of science and industry in Europe for the benefit of its citizens.
PRACE and EuroHPC are expected to invest in an ambitious programme for promoting such synergies and a critical aspect of this will be the promotion of technical staff to curate algorithms and software and their effective development on HPC infrastructures. The PRACE Scientific Steering Committee has formulated this third version of the scientific case in relation to a number of areas of major societal relevance, and identified both success stories and breakthroughs that will be possible with investments in next generation infrastructure.
