  1. PaPP ̶ Developing Future Proof Parallel Software Mats Brorsson, Professor, Swedish Institute of Computer Science Oct 26, Paris, France ARTEMIS Joint UndertakingThe public private partnership for R&D actors in embedded systems

  2. This is PaPP • Predictable performance, for • Parallel applications, on • Heterogeneous embedded manycores

  3. PaPP -- Consortium

  4. Technological Innovation • Multiple application domains • Task-centric parallelism • Separation of concerns • Enables better resource management • Multi-level, co-operative scheduling and resource management • Hypervisor • OS(s) • RTS:s • Demonstrator of feasibility for multiple domains and architectures Domain A Domain B Domain C DSL:s Framework Standard languages Run-time systems Run-time systems OS1 OS2 Hypervisor Arch 1 Arch 2 Arch 3

  5. Approach • Revisit the entire software stack: • Programming model • Performance modelling tools • System software (RTS, OS) • Hardware abstraction • With the purpose of enabling performance predictability and portability

  6. Overall objective • Achieve predictable performance portability of software when moved from current platforms to future parallel platforms Tle-GX100 Nvidia CARMA

  7. Sub-objectives • Efficient and accurate performance models • Demonstrated performance portability across platforms • Demonstrated portability of the software stack across application domains • Vastly improved resource usage and management • Reusable parallel software components • Improved software developer productivity

  8. Market Innovation • For the space application domain • Verify ongoing ESA features • For the mobile communication domain • Improve the power/performance trade-offs • Cutting time of (re)certification • In the multimedia domain • Reuse of media processing IP:s on wider set of heterogeneous processors

  9. Next steps • Yearly integration of tool chains • Workshops and tutorials • Demonstrators • Contribution to ARTEMIS Tools platforms
