The cluster consists of four nodes, each equipped with a Samsung Exynos 5 Octa (5422) CPU. The system promises high computational power under low energy consumption. In this paper, the applicability of such a systems to scientific problems is investigated. Therefore, flow computations using a lattice-Boltzmann method are employed to evaluate the single core, single node, and multi-node performance and scalability of the cluster. The lattice-Boltzmann code is part of a larger simulation framework and scales well across several high-performance computers. Performance measurement results are juxtaposed to those obtained on high-performance computers and show that the ODROID-MC1 can indeed compete with high-class server CPUs. Energy measurements corroborate the ODROID’s energy efficiency. Its drawbacks result from the limited amount of available memory, the corresponding memory bandwidth, and the low-performing Cortex A7 cores of the big.LITTLE architecture. The applicability to scientific applications is shown by a three-dimensional simulation of the flow in a slot burner configuration. 000861525 536__ $$0G:(DE-HGF)POF3-513$$a513 - Supercomputer Facility (POF3-513)$$cPOF3-513$$fPOF III$$x0 000861525 588__ $$aDataset connected to CrossRef 000861525 7001_ $$0P:(DE-Juel1)144441$$aPleiter, Dirk$$b1 000861525 7001_ $$0P:(DE-HGF)0$$aSchröder, Wolfgang$$b2 000861525 773__ $$0PERI:(DE-600)2020551-X$$a10.1016/j.future.2018.12.059$$gVol. 95, p. 149 - 162$$p149 - 162$$tFuture generation computer systems$$v95$$x0167-739X$$y2019 000861525 8564_ $$uhttps://juser.fz-juelich.de/record/861525/files/Lintermann_FGCS_OdroidMC1.pdf$$yOpenAccess 000861525 8564_ $$uhttps://juser.fz-juelich.de/record/861525/files/Lintermann_FGCS_OdroidMC1.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000861525 909CO $$ooai:juser.fz-juelich.de:861525$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000861525 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)165948$$aForschungszentrum Jülich$$b0$$kFZJ 000861525 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)144441$$aForschungszentrum Jülich$$b1$$kFZJ 000861525 9131_ $$0G:(DE-HGF)POF3-513$$1G:(DE-HGF)POF3-510$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lSupercomputing & Big Data$$vSupercomputer Facility$$x0 000861525 9141_ $$y2019 000861525 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000861525 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology 000861525 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bFUTURE GENER COMP SY : 2017 000861525 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000861525 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000861525 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000861525 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000861525 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000861525 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000861525 920__ $$lyes 000861525 9201_ $$0I:(DE-Juel1)JSC-20090406$$kJSC$$lJülich Supercomputing Center$$x0 000861525 9201_ $$0I:(DE-82)080012_20140620$$kJARA-HPC$$lJARA - HPC$$x1 000861525 980__ $$ajournal 000861525 980__ $$aVDB 000861525 980__ $$aI:(DE-Juel1)JSC-20090406 000861525 980__ $$aI:(DE-82)080012_20140620 000861525 980__ $$aUNRESTRICTED 000861525 9801_ $$aFullTexts
