ASCI DCE Flyer

Vision

Facilitate the joint development and use of terascale applications by establishing a common set of distributed computing services at each of the three laboratories. These computing services are structured to give users a single view of the unique ASCI high-performance computing resources in a secure, user-authenticated environment with a common home directory.

Objectives

• Establish secure middleware infrastructure, spanning PSE from TFLOP to desktop
• Single sign-on for secure, manageable access to ASCI resources
• Enable secure file access and sharing through an ASCI-wide file system with integrated archival storage
• Implement technical solutions for NTK separation

Approach

The Tri-Lab Distributed Computing team (a consortium of computer scientists from LLNL, LANL and SNL) is collaborating to coordinate

• implementations of the DCE and DFS technologies from the The Open Group
• security plans and MOUs for cross-cell trust between sites
• with other PSE components and platforms for a well integrated solution
• with other collaboratory efforts, including the ESnet DCE Working Group
• "early on" with users to establish testbeds and evaluate technologies

Each site will "Think globally, Act locally" when building a DCE infrastructure at their site.
