Cosmology Application

• C/F77 cosmology application
• Employs adaptive mesh refinement (AMR).
• Currently runs as a shared memory multithreaded
  application
• Ideal candidate already an object-oriented
  code, the objects are coarse-grain, interesting
  communication relationships
• Typical simulation spawns 500-1000 objects
  (grids) which have both concurrent and sequential
  modes of execution
• Grids easily fit into the RAM memory of typical
  desktop or clustered PC

NCSA Symera current lines of development...

• Port the cosmology application and let it drive
  the development of Symera as a supporting
  middle-tier system
• Leverage off of our COM-centric approach and
  focus on specific issues concerning development
  and large application management
• Address the strengths of our system and provide
  users with our component-based tools such as
  scheduling mechanisms, state management and
  dynamic application partitioning.
• Establish inter-operative relationships with
  Globus, Condor and
• other Grid projects
