Programming Environment Products Status and Update Sylvia Crain This paper will address the road map and directions for the Cray Programming Environment and MIPSpro compiler releases. General product directions and specifics of recent and upcoming release will be discussed. Additionally the strategy for hardware and software support for Cray Programming Environments and the focus for bug resolution will be addressed. Cray Product Installation and Configuration Scott Grabow The Common Installation Tool (CIT) has had a large impact upon the installation process for Cray software. The migration to CIT for installation has yielded a large number of questions about the methodology for installing new software via CIT. This document discusses the installation process with CIT and how CIT's introduction has brought about changes to our installation process and documentation. Providing Distributed Services in a Heterogeneous Computing Environment Peter Morreale, John Clyne, Craig Ruff, Mark Uris, and Don Middleton The National Center for Atmospheric Research (NCAR) Distributed Computing Services (DCS) project is a five year effort aimed at providing NCAR supercomputing services on local users desktops. The initial effort has focused on providing NCAR Mass Storage System (MSS) services to major compute servers including Cray, SGI, IBM, and Sun systems. The DCS system is designed around OSF's DCE software. DCS makes liberal use of the DCE Remote Procedure Call (RPC) mechanism, as well as the Cell Directory Service (CDS). This paper discusses the design of the NCAR DCS system as currently implemented as well as future directions. MPI Regression Testing and Migration to Origin 2000 Terry Nelson The computing industry, for economic and technical reasons, is moving inexorably towards an increasingly parallel environment. One of the major paradigms to accomplish this is message passing, and one of the major tools in this area is MPI. This paper will describe a set of Fortran and C regression tests which test MPI functionality and performance. A series of runs on a C90, J90, and Origin 2000, as well as tests with production sized jobs, will be described. Particular attention will be given to the migration of programs from the C90 and J90 environments to the Origins. Table of Contents | Author Index | CUG Home Page | Home (Title Page)
