Some SARS background info…
When the medical staffs of several key hospitals in Taiwan
were quarantined by the SARS epidemic, threatening to
make a critical situation even worse, computer scientists
there, in the U.S., and throughout the Asia Pacific Rim turned
to grid computing technology and old-fashioned teamwork.
PRAGMA -- the Pacific Rim Applications and Grid
Middleware Assembly -- showed how relationships and
expertise developed to tackle computational research could
also help thousands of SARS patients in Taiwan.

SARS and AG
•There were designated hospitals to be quarantined.
•Doctors and patients in those hospitals would be
quarantined
•But there would be new discoveries about the SARS form
those hospitals
•Quarantined doctors had many valuable first-hand data, eg
SARS patients` X-ray, to discuss with other doctors and the
only way is via video conferencing
•And AG could help

AG & Collaborative teaching



What?
• Giving lectures collaboratively
• Means several teachers for one class
How?
• Demo the possibility on Aug 14. 2003
• 5 professors/universities in Taiwan involved
• The facilitator was joining the session from Australia
• Session was via NCHC’s bridge server
Hope to give accredited courses via AG in this coming fall

More friendly user interface
Vic codec modification
Security
Inter-domain multicast
AG over VPN
Keep being supportive for any future AG
deployments in Taiwan
Thanks for those who had helped us during SARS.
