Tackling this challenge requires advanced coupling and supercomputing technologies for earth system models that are discussed in this study, utilizing the example of the implementation of the newly developed Terrestrial Systems Modeling Platform (TerrSysMP) on JUQUEEN (IBM Blue Gene/Q) of the Jülich Supercomputing Centre, Germany. The applied coupling strategies rely on the Multiple Program Multiple Data (MPMD) paradigm and require memory and load balancing considerations in the exchange of the coupling fields between different component models and allocation of computational resources, respectively. These considerations can be reached with advanced profiling and tracing tools leading to the efficient use of massively parallel computing environments, which is then mainly determined by the parallel performance of individual component models. However, the problem of model I/O and initialization in the peta-scale range requires major attention, because this constitutes a true big data challenge in the perspective of future exa-scale capabilities, which is unsolved. 000171937 536__ $$0G:(DE-HGF)POF2-246$$a246 - Modelling and Monitoring Terrestrial Systems: Methods and Technologies (POF2-246)$$cPOF2-246$$fPOF II$$x0 000171937 536__ $$0G:(DE-HGF)POF3-255$$a255 - Terrestrial Systems: From Observation to Prediction (POF3-255)$$cPOF3-255$$fPOF III$$x1 000171937 536__ $$0G:(DE-HGF)POF2-411$$a411 - Computational Science and Mathematical Methods (POF2-411)$$cPOF2-411$$fPOF II$$x2 000171937 536__ $$0G:(DE-Juel-1)ATMLPP$$aATMLPP - ATML Parallel Performance (ATMLPP)$$cATMLPP$$x3 000171937 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000171937 7001_ $$0P:(DE-HGF)0$$aGoergen, K.$$b1 000171937 7001_ $$0P:(DE-Juel1)151405$$aKollet, S.$$b2$$ufzj 000171937 7001_ $$0P:(DE-HGF)0$$aShrestha, P.$$b3 000171937 7001_ $$0P:(DE-HGF)0$$aSulis, M.$$b4 000171937 7001_ $$0P:(DE-HGF)0$$aRihani, J.$$b5 000171937 7001_ $$0P:(DE-Juel1)132112$$aGeimer, M.$$b6$$ufzj 000171937 773__ $$0PERI:(DE-600)2456729-2$$a10.5194/gmdd-7-3545-2014$$gVol. 7, no. 3, p. 3545 - 3573$$n3$$p3545 - 3573$$tGeoscientific model development discussions$$v7$$x1991-962X$$y2014 000171937 8564_ $$uhttps://juser.fz-juelich.de/record/171937/files/FZJ-2014-05491.pdf$$yOpenAccess 000171937 8767_ $$92014-07-02$$d2014-07-08$$eAPC$$jZahlung erfolgt 000171937 909CO $$ooai:juser.fz-juelich.de:171937$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire 000171937 915__ $$0LIC:(DE-HGF)CCBY3$$2HGFVOC$$aCreative Commons Attribution CC BY 3.0 000171937 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000171937 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000171937 9141_ $$y2014 000171937 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)159138$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000171937 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)151405$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000171937 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132112$$aForschungszentrum Jülich GmbH$$b6$$kFZJ 000171937 9132_ $$0G:(DE-HGF)POF3-255$$1G:(DE-HGF)POF3-250$$2G:(DE-HGF)POF3-200$$aDE-HGF$$bPOF III$$lMarine, Küsten- und Polare Systeme$$vTerrestrische Umwelt$$x0 000171937 9132_ $$0G:(DE-HGF)POF3-511$$1G:(DE-HGF)POF3-510$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bPOF III$$lKey Technologies$$vSupercomputing & Big Data$$x1 000171937 9131_ $$0G:(DE-HGF)POF2-246$$1G:(DE-HGF)POF2-240$$2G:(DE-HGF)POF2-200$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bErde und Umwelt$$lTerrestrische Umwelt$$vModelling and Monitoring Terrestrial Systems: Methods and Technologies$$x0 000171937 9131_ $$0G:(DE-HGF)POF3-255$$1G:(DE-HGF)POF3-250$$2G:(DE-HGF)POF3-200$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-255$$aDE-HGF$$bErde und Umwelt$$lTerrestrische Umwelt$$vTerrestrial Systems: From Observation to Prediction$$x1 000171937 9131_ $$0G:(DE-HGF)POF2-411$$1G:(DE-HGF)POF2-410$$2G:(DE-HGF)POF2-400$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bSchlüsseltechnologien$$lSupercomputing$$vComputational Science and Mathematical Methods$$x2 000171937 9201_ $$0I:(DE-Juel1)IBG-3-20101118$$kIBG-3$$lAgrosphäre$$x0 000171937 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x1 000171937 9801_ $$aFullTexts 000171937 980__ $$ajournal 000171937 980__ $$aVDB 000171937 980__ $$aI:(DE-Juel1)IBG-3-20101118 000171937 980__ $$aI:(DE-Juel1)JSC-20090406 000171937 980__ $$aUNRESTRICTED 000171937 980__ $$aFullTexts 000171937 980__ $$aAPC 000171937 981__ $$aI:(DE-Juel1)JSC-20090406
