This is a terrain following coordinate ocean modeling code using advanced numerical methods and physical parameterizations, intended to expand capabilities of the existing family of SPEM/SCRUM/POM modelsin terms of numerical/computational performance, grid resolution, degree of realisticity in simulating ocean. From the computer engineering point of view the code employs explicit, coarse-grainedparallelization approach based on a two-level hierarchical subdomain partitioning (blocking) in bothhorizontal dimensions, and using either multi-threaded (for shared-memory architectures), or MPI (fordistributed), or both simultaneously (hybrid, running Open MP threads within each MPI subdomain)implementation to ensure affinity with the architecture of modern computing hardware – Linux clustersof SMP nodes with multi-core CPUs.Grant and Funding History: Participated as Co-Principal Investigator (Co-PI) in several researchgrants under guidance of Prof. McWilliams.
