Approach

Revisit the entire software stack:Programming modelPerformance modelling toolsSystem software (RTS, OS)Hardware abstraction

With the purpose of enabling performance predictability and portability

PaPP – Developing Future-Proof Parallel SoftwareARTEMIS Joint Undertaking

Overall objective

Achieve predictable performance portability of software when moved from current platforms to future parallel platforms
