1. Who are the users? BioExcelCoEGSSECAMEoCoE academia and industry policy makers, public bodies, NGOs, industries, academia, SME extended CECAM academic community + industrial associates researchers of meteo, material, water & fusion ESiWACEMaXNoMaDPOP Climate scientists & centres performing weather prediction ICT, energy, health pharma, transportation manufacturing Academic & industrial researchers and the public Code developers interested on assessment of applications

2. How close to exascale? BioExcelCoEGSSECAMEoCoE Exascale target varies between the codes due to the nature of the algorithms Hard to estimate not primarily aimed at exascale - ESiWACEMaXNoMaDPOP Currently climate modeling is far away from exascale doubling scalability of codes every 18-24 months Massively large-scale materials information will lead to exascale Performance analysis is a mandatory step to move real codes to exascale

3. Co-Design? BioExcelCoEGSSECAMEoCoE work with h/w manufacturers for early porting & optimization on general & accelerator systems Co-Design with selected vendors outside of the consortium -- ESiWACEMaXNoMaDPOP - part of the co-design is carried out with a SME Apache Flink system, preliminary results expected in 6 months Analysing performance of applications gives insight for co-design

4. PRACE 0.5% for HPC CoEs BioExcelCoEGSSECAMEoCoE large-scale benchmarking / verification of supported software At a project advanced stage Under discussion (3 PRACE centers are partners) large scale performance analysis & code testing ESiWACEMaXNoMaDPOP Evaluation of PRACE software stack for Earth System modeling internal development & specific enabling actions for HPC users calculations demanded by the users, re- computation of suspected low-veracity data large scale studies / or when user has no resources available
