Ocean Prediction with the Hybrid Coordinate Ocean Model (HYCOM)

This chapter provides an overview of the effort centered on the HYbrid Coordinate Ocean Model (HYCOM) to develop an eddy-resolving, real-time global and basin-scale ocean prediction system in the context of the Global Ocean Data Assimilation Experiment (GODAE).

The NRL layered ocean model

Abstract We describe the portable scalable implementation of the NRL Layered Ocean Model (NLOM). Scalability is based primarily on the tiled data parallel parallel programming paradigm. This is sufficiently general that the actual technique used on a given machine to obtain scalability can be selected at compile time from: (i) data parallel, (ii) SPMD message passing, (iii) autotasking, or (iv) SPMD message passing between multi-processor autotasked systems. The code is thus portable onto all machine types likely to be used by ocean modelers.
