To this end, we benchmarked our MPI-parallel fluid solver NaSt3DGPF on several HPC compute nodes of the cloud system. Our solver can use CPUs and GPUs to calculate the simulation results. With a pre-requested number of instances we observe for both, CPUs and GPUs, good scalability even for a larger number of parallel processes, provided that the GPUs run in the non-ECC mode. Furthermore, we see a high potential for medium sized parallel compute problems which are typically present in industrial engineering applications.}, keywords = {}, doi = {10.1109/NCCA.2011.19}, issn = {}, annote = {series}, http = {http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6123441&tag=1} }
