What is ApGrid?

A meeting point for all Asia-Pacific HPCN
  researchers
  ..doing grid-related work
Communication channel to the Global Grid
  Forum, and other grid communities
Pool for finding international project
  partners
 Not a single source funded “project”!
  Unlike EuroGrid, eGrid, IPG, etc.

ApGRID: motivations (1)

 Establish a regional wide testbed for
  global computing (Grid and/or Meta)
   Disseminating research activities
   Providing an easy-access environment for
    researchers, students, vendors, etc.
   Improving interoperability of existing tools
   Testbed for software development and trial
    to have evaluation of usability and to
    archive performance numbers
   Finding demonstrative applications
ApGRID: motivations (2)

  Create a competitive/collaborative community
   to the iGRID and the eGRID for:
    Making international collaborations
    Supporting and collaborating with network people,
     ex. APAN, IM-net, etc.
    Attempt to negotiate for standardization with real
     experience (in Global Gridforum.)
  Also, domestic (intra-country) service
    Nation-wide
       Several “non-cooperative” network communities 
       Seeking governmental and/or industrial funding
    Campus-wide
       Find Volunteers within our friends

 Ninf server + Ninf RPC protocol
    transparent execution of Ninf library program on
    computational server
 Ninf database server
    direct query on accurate constant database
 Ninf Client Interface
    easy-to-use programming interface
 Ninf Metaserver
    scheduling of computation, asynchronous and
    automatic parallel computation,
Ninf RPC Protocol

   Exchange interface information at run-time
     No need to generate client stub routines (cf. SunRPC)
     No need to modify a client program when server’s libraries
      are updated.

  Just kicked off, and some of the resources
   are ready, but still we need:
    Hiring people to maintain and to install the regular
     services initially
    Considering to have meeting in mid. March, 2001
    Contributing to the GGF
  Enrolling more partners
    Reserved: apgrid.org, Web site will be open shortly
    Find international partners
    Creating much stronger relation with APAN
     activities
   Summary
 Some success stories
   Collaboration with Application Scientists
   International Collaborations
      Osaka-U/UCSD (Globus)
      NetSolve/Ninf Collaboration
   WGCC2000, Grid Forum, metacomputing WS
   Government funded several projects
 the Asia-Pacific Grid (ApGrid)
   TACC is ready for providing computing resources
