ABSTRACT
Re-factoring HBM for XEON-PHI Jacob Weismann Poulsen and Per Berg, DMI Abstract: HBM, the HIROMB-BOOS Model, is an ocean circulation model code that is developed and applied at DMI in different setups from operational forecast model for the official Danish stormsurge warning system to research projects such as climate and bio-geo-chemical modelling on Pan-European scale. The model code is being developed for present and future architectures, and therefore has matured support for shared and distributed memory systems using openMP and MPI, respectively. More recently, our attention has been towards many-core architectures, and we would like to share some details of the work we did for re-factoring for Intel's XEON PHI co-processor. Some of our work was published e.g. here: Better Concurrency and SIMD on HBM by Jacob Weismann Poulsen, Per Berg and Karthik Raman Chapter 3 in High Performance Parallelism Pearls -- Multicore and Many-core Programming Approaches.
