Applications Performance of the Parallel Climate Model on the SGI Origin 2000 and the CRAY T3E Thomas Bettge, Anthony Craig, Rodney James, Warren G. Strand, Jr., and Vincent Wayland The DOE Parallel Climate Model (PCM) is a tightly coupled model of the earth's physical and dynamic climate system, and includes fully active components of the atmosphere, ocean, land, and sea ice. It was designed for use on the T3E massively parallel machine architecture, and adapted for use on the distributed shared memory Origin 2000. The computational design of the PCM is discussed. Performance experiences on the T3E and Origin 2000 are presented. Experiences with Porting the Parallel CFD Code N3S to Fortran 90 Jean-Pierre Grégoire We first present the difficulties we have overcome using the CF90 parallelizer-compiler to obtain a parallel version of the N3S code which is similar to that obtained using the CF77 parallelizer-compiler. We also discuss the stability of the results produced after this porting. We finally describe the difficulties encountered in controlling the memory consumption when moving from the Fortran 77 static memory allocation to the Fortran 90 dynamic memory allocation. Teraweb™: Web-based High Performance Computing Joel Neisen, David Pratt, and Ola Bildtsen Using standard browsers, Teraweb provides a seamless and unified graphical environment for users of High Performance Computing (HPC) equipment. Teraweb can be used to run computational models, manipulate data files, print or visualize results, or display system usage information without having to learn cryptic command-line interfaces of operating system commands.
