European joint Effort toward a Highly Productive Programming Environment for Heterogeneous Exascale Computing (EPEEC)

Livrables

Revised application specification and porting report

Updated version of the content of D52 with feedback from application developers after preliminary assessment of the porting of simplified test programs This report will also feature the latest performance figures on the simplified test programs after their adaptation to the GASPIOmpSs and OmpSsArgoDSM models This is an outcome of Task 52

User's guide for application developers and system managers

This document is the main outcome of Task 47

Training Plan

This deliverable will specify all training needs, activities, and materials needed during the project. This plan will also include exploiting the existing training channels such as PRACE training centres, among others to participate actively with the suggested trainings, and trying to accommodate the courses to their requirements, if any. The initial idea is to organise two courses each year about the hot topics defined by the various work package leaders, as well as to include sessions in summer schools such as PUMPS, ISC/SC tutorials or BoF sessions, or the organisation of a dedicated PATC course at BSC and the participation in the yearly hackathon.

Final dissemination report

The dissemination report will include the various dissemination activities from the third project year and its analysis

Initial report of OmpSs+OpenACC/OpenMP interoperability

Initial report of the proposed syntax for the combination of OmpSs and accelerator kernels defined with OpenACC and OpenMP syntaxes. Includes semantics and syntax compatibility of OmpSs and OpenACC/OpenMP accelerator kernel definitions, as well as proposals of interoperability improvement for the OpenACC and OpenMP specifications. This is an outcome of Task 3.2.

Initial application specification and porting report

This document will report on the main programming features of application codes and the definition of simplified test programs that are representative of the main compute-intensive, data-intensive, and extreme-data parts of the full application codes. It will also report on the first development actions on these simplified test programs. This is an outcome of Task 5.2.

Specification report on requirements of application codes
