Abstract : This report describes the portable scalable implementation of the NRL Layered Ocean Model (NLOM). Scalability is based primarily on the tiled data 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: (1) data parallel, (2) SPMD message passing, (3) autotasking, or (4) SPMD message passing between multi-processor autotasked systems. The code is thus portable onto all machine types likely to be used by ocean modelers.
