Description

The HBM (HIROMB-BOOS Model) ocean circulation model scaling on the selected PRACE Tier-0 systems is described. The model has been ported to the BlueGene/Q architecture and tested against OpenMP and mixed OpenMP/MPI parallel performance and scaling with a given test case scenario. Benchmarking of the selected computational kernels and model procedures with a micro-benchmarking module has been proposed for further integration with the model code. Details on the micro-benchmark proposal and results of the scaling tests are described.
