D2.6.1 Operational model analysis and initial specifications

PRACE will provide the research community with a single, unique permanent infrastructure, thus permitting and encouraging users to invest in the development of simulation codes based on computational sciences.
A consistent operational model is thus required for PRACE to achieve this goal, in the face of evolving technologies and architectures, across multiple interconnected distributed sites. It must also allow for building a coherent ecosystem ensuring that PRACE tier-0 systems are easy to use for users familiar with the other 2 tiers of the European HPC environment.
This document presents an analysis of the operational model for PRACE and initial specifications.
