ERDC MSRC/PET TR/00-08 Dual-Level Parallelism Improves Load-Balance in Coastal Ocean Circulation Modeling

Numerical grid generation techniques play an important role in the numerical solution of partial di erential equations on arbitrarily-shaped regions. For coastal ocean modeling, in particular, a one-block grid covering the region of interest is most commonly used. Most bodies of water have complicated coastlines; e.g., Persian Gulf and Mediterranean Sea. In such a physical domain, the number of...

ERDC MSRC/PET TR/00-12 Scientific Visualization of Water Quality in the Chesapeake Bay

This paper describes our experience in designing and building a tool for visualizing the results of the CE-QUALICM Three-Dimensional Eutrophication Model, as applied to water quality in the Chesapeake Bay. This model outputs a highly multidimensional dataset over very many timesteps – outstripping the capabilities of the visualization tools available to the research team. As part of the Army En...

ERDC MSRC/PET TR/00-32 Practical Experiences with the Fortran Pthreads API

With the growing popularity of symmetric multiprocessors (SMPs), shared-memory programming models have become more important. Of particular relevance to scienti c programmers will be those paradigms that can be used within message-passing codes. POSIX Threads (Pthreads) is one such shared-memory programming model. While only de ned for use within C programs, the Fortran API to Pthreads (FPTHRD)...
