First Co-design report. Deliverable D4.3 of the HORIZON-EUROHPC-JU-2021-COE-01 project MaX (101093374)

This deliverable is the first of task T4.1 of WP4. Its purpose is the exploration of the co-design opportunities for applications involved in the MaX project. The methodology exposed in this document will help to analyze the status of the MaX codes in terms of porting and targeting the best performance on the European processor Rhea from the EPI project, developed by SiPearl and that will equip the European Pilot for Exascale “EUPEX”. Focus is the exploitation of Rhea characteristics such as SVE (Scalable Vector Extension) vectorization and high-speed memories, such as HBM, and the development of mini-apps to assess performance of the MaX applications on future platforms.
