Welcome to PACI.org. The information contained on this Web site is your first step to understanding, accessing, and using the Partnerships for Advanced Computational Infrastructure (PACI) resources.
The following information can be found at this Web site:
Started in 1997, PACI is a program of the National Science Foundation's (NSF's) Directorate for Computer and Information Science and Engineering (CISE). PACI is creating the foundation for meeting the expanding need for high-end computation and information technologies required by U.S. academic researchers. PACI partners contribute to the development of the information infrastructure by developing, applying and testing the necessary software, tools, and algorithms that contribute to the further growth of this "national grid" of interconnected high-performance computing systems.
The NSF's Division of Shared Cyberinfrastructure (SCI) provides support for and access to high-end computing infrastructure and research through the PACI program. PACI offers more than 22 high-performance computing systems that represent an unprecedented amount of computational resources made available by the NSF. The following are PACI's national partnerships and leading-edge sites:
|
National Computational Science Alliance (Alliance) |
National Partnership for Advanced Computational Infrastructure (NPACI) |
Pittsburgh Supercomputing Center (PSC) |
|
The Alliance is a partnership made up of more than 50 academic, government, and industry research partners from across the United States. The University of Illinois' National Center for Supercomputing Applications (NCSA) is a PACI leading-edge site and is also the lead site for the Alliance partnership. |
NPACI is a partnership of 46 institutional members from 20 states across the country and four international affiliates. The San Diego Supercomputer Center (SDSC) is a PACI leading-edge site, and is also the lead site for the NPACI partnership. |
PSC is a PACI leading-edge site operating the 6-Tflop NSF Terascale Computing System (TCS), an HP Alphaserver Cluster comprising 750 4-processor compute nodes. In addition, PSC's 512-processor Cray T3E-900 is available to the U.S. computational science community via the PACI program. |
Launched by NSF in August 2001, the TeraGrid is a multi-year effort to build and deploy the world's largest, fastest, distributed infrastructure for open scientific research. It will eventually include 20 teraflops of computing power distributed at five sites. The TeraGrid also will include facilities capable of managing and storing nearly 1 petabyte of data, high-resolution visualization environments, and toolkits for grid computing. These components will be tightly integrated and connected through a network operating at 40 gigabits per second. TeraGrid resources are allocated through the PACI Allocations process.
The computational resources and services of the PACI program are complemented by the joint Education, Outreach and Training-Partnership for Advanced Computational Infrastructure (EOT-PACI). EOT-PACI's mission is to develop human resources through innovative use of emerging technologies to understand and solve problems.
