Project: NPACI-Grid
Description: The NPACI-Grid's goal is to provide an advanced cyber-infrastructure for the scientific computing requirements of the NPACI community. This production class grid consists of hardware, software, and other resources located at SDSC, TACC, UMich, and CalTech. These resource sites have deployed an integrated set of grid middleware and advanced NPACI applications to enable a robust environment for your computing needs, and enable you to perform scientific research at ever increasing levels of simulation and sophistication. NPACI represents a classic Virtual Organization and a great opportunity for grid technologies: * the resources comprising the grid belong to four different administrative domains, each with their own rules, regulations, requirements, accounting procedures, etc. * the resources are heterogeneous and distributed: a large AIX cluster in San Diego; a 435 GFlop AMD based Linux cluster in Michigan; three large shared-memory server nodes in Texas delivering 1160 GFlops; etc. Some of the advantages to using the grid interface to these resources include: Scheduler abstraction: using the Resource Specification Language from the Globus Toolkit, you don't need to code job submission in different formats depending on whether the job(s) will be submitted to LoadLeveler or PBSPro Security: single sign on for multiple hosts Advanced job submission capabilities from Condor-G, such as providing a single access point for running and monitoring jobs across NPACI Grid resources Network bandwidth monitoring and prediction between resource sites via the Network Weather Service
Participants: The NPACI Grid comprises four major resource sites (SDSC, TACC, Caltech, and the University of Michigan).
