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

ApGrid: Current Status
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
