The key results achieved during the sprint are an evaluation of the parallel efficiency of a standalone application of the ICON-Ocean model with PDAF, code analysis, and the development of a strategy for GPU offloading. Preliminary GPU porting of core PDAF subroutines and subsequent performance testing were also carried out. 001049575 536__ $$0G:(DE-HGF)POF4-5111$$a5111 - Domain-Specific Simulation & Data Life Cycle Labs (SDLs) and Research Groups (POF4-511)$$cPOF4-511$$fPOF IV$$x0 001049575 536__ $$001LK2107B1$$aBMFTR-01LK2107B1 - Nationale Modellierungsstrategie - ESM-Unterstützungsteam (natESM) (01LK2107B1)$$c01LK2107B1$$x1 001049575 7001_ $$0P:(DE-HGF)0$$aNerger, Lars$$b1 001049575 8564_ $$uhttps://www.nat-esm.de/services/support-through-sprints/documentation/250710-natesm_sprint_report_pdaf2gpu_final.pdf 001049575 8564_ $$uhttps://juser.fz-juelich.de/record/1049575/files/natesm_sprint_docu_pdaf2gpu.pdf$$yOpenAccess 001049575 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)200302$$aForschungszentrum Jülich$$b0$$kFZJ 001049575 9101_ $$0I:(DE-HGF)0$$6P:(DE-HGF)0$$aExternal Institute$$b1$$kExtern 001049575 9131_ $$0G:(DE-HGF)POF4-511$$1G:(DE-HGF)POF4-510$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5111$$aDE-HGF$$bKey Technologies$$lEngineering Digital Futures – Supercomputing, Data Management and Information Security for Knowledge and Action$$vEnabling Computational- & Data-Intensive Science and Engineering$$x0 001049575 9141_ $$y2025 001049575 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 001049575 920__ $$lyes 001049575 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x0 001049575 980__ $$areport 001049575 980__ $$aVDB 001049575 980__ $$aUNRESTRICTED 001049575 980__ $$aI:(DE-Juel1)JSC-20090406 001049575 9801_ $$aFullTexts
