ASC Project Goals

• Develop a useful software base for applying the
  numerical
• treatment of Einstein theory to astrophysics
  research.
• Promote collaborative development among
  distributed
• teams of scientists, researchers and
  developers.
• Make software and tools widely-available to
• astrophysics and computational science
  researchers.
• To coordinate the use of computational and
  data-storage
• resources among members of the astrophysics
  community.

ASC Proposed Solution

• Build a Web Portal
• To enable a Virtual Organization of
  astrophysicists and
• computational science researchers to
  collaborate from any
• location in the world.
• Use standard Grid technologies
• To overcome the practical obstacles of
  accessing resources
• due to the tremendous variety of resource
  types, mechanisms,
• and access policies that exist today.
• Support development with Cactus
• Cactus provides the modular framework we
  require for building
• high-performance, parallelized applications.
  Plus, Cactus
• compiles and runs in most computing
  environments.

ASC Grid Architecture
The ASC Portal is an N-tier, Web-based
application that is directly supported by several
key services and relies upon Grid technologies to
access remote resources.

GridSphere Overview

• GridSphere is a Java-based Grid application
  server development framework that extends the
  JavaCoG Toolkit and other public libraries to
  support the efficient use of Grid Services among
  multiple users.
• GridSphere provides packages with extensible APIs
  for managing users, security, information about
  resources, accessing services, and managing
  Cactus applications.
• GridSphere provides runtime administrative
  support, and this is particularly important for
  Grid Portals since they are always up,
  highly-available services.

8
Orbiter Overview

• Orbiter is a Java Servlets/JSP application server
  framework, built upon GridSphere, for delivering
  end-user applications as DHTML pages (and more
  recently Java Applets).
• Orbiter packages collections of JSP pages as
  modules to which access policies can be set on
  a per user basis.
• Our end goal is to develop an extensible JSP tag
  framework to will make it easier to construct
  DHTML pages for delivering Grid application
  services.
• We plan to extend Orbiter to use XML/XSLT as
  intermediary step to producing DHTML pages
  (looking at JetSpeed for content delivery).

GridLab Portal Development

• GridLab Portals will be developed with
  GridSphere/Orbiter, from which we plan to develop
  an open-source project.
• We will extend GridSphere with an OGSA
  communication framework.
• OGSA will provide us with a communication
  infrastructure with which we can construct Grid
  portals as collections of distinct services,
  where each service may be administered from
  distinct host environments.
• This will make it easier to plug services
  developed by other Work Packages into our Grid
  application server framework.

GridSphere/Orbiter Development
GridSphere/Orbiter
GridSphere will get its own hosting environment
to encourage collaboation fromother Grid Portal
projects.
However, GridSphere will likely be supported by
the GridLab project in the long term.
