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.}, cin = {JSC / JARA-HPC}, ddc = {004}, cid = {I:(DE-Juel1)JSC-20090406 / $I:(DE-82)080012_20140620$}, pnm = {513 - Supercomputer Facility (POF3-513)}, pid = {G:(DE-HGF)POF3-513}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000465509600014}, doi = {10.1016/j.future.2018.12.059}, url = {https://juser.fz-juelich.de/record/861525}, }
