SPECTRUM D5.3 Landscape of RIs: technologies, services, gaps

This Deliverable documents and analyzes the technical characteristics of  20 European e-Infrastructures in the areas of High-Performance Computing, High-Throughput Computing,  Cloud Computing, and Data, which are open for use by European scientists. It compares and contrasts them with the requirements of European research communities, in particular the High-Energy Physics and Radio Astronomy fields, with a focus on the use cases described in Spectrum Deliverable D5.1 (Representative use cases: analysis and alignment), and identifies and discusses recommendations for the future evolution of the e-Infrastructure landscape in Europe.
