Background
• TeraGrid User Portal (TGUP) is a web portal
that aggregates and simplifies access to
TeraGrid information and services for active
TeraGrid users.
• The purpose of the TGUP is to:
– Make resources and services easier to use.
– Increasing productivity.
– Facilitate greater impact of the TeraGrid project.
Background
• The current TGUP provides both information and
applications.
–
–
–
–
–
–
Account, allocation, and user profile management
Resource monitoring
Remote visualization
Remote login and file management
Education and training
Searchable knowledge base
• It does a lot of stuff!!
• Currently receives about and 300,000 hits/month
Background
• New trends are appearing:
– Mobile web traffic more than doubled last year
and industry leader, Cisco, predicts this will
continue at least through 2013 [2].
– Today, one third of mobile users own a
smartphone with another third indicating they
plan on purchasing one as their next mobile
device [3].
Background
Two approaches taken to address this changing
market.
• Native Apps
• Webapps
Design
• Purpose is to keep users connected and informed
while on the go.
• Built for smartphone audience.
• Driving use cases are influenced by the user
interface, though not defined by them.
• Webapp solution to serve most popular platforms
first (Apple and RIM > 78% of U.S. web requests),
keeping in mind those coming on (WebOS,
Android)
• Minimally require that all browsers support
HTML, CSS, JavaScript, and cookies.
Design
Initial subset of features
• User job information
• TeraGrid news items
• TeraGrid resource status
• User allocation information and balances
• Direct contact mechanism for the TeraGrid
Help Desk
• User profile information and updating
Architecture
Reuse as much of the existing TeraGrid SoA as
possible.
• MyProxy Single Sign-on
• TeraGrid Integrated Information Services
• TeraGrid User Profile Service
• GridPort Information Repository
• Inca Grid Monitoring Service
• MetaData Directory Service (MDS)
• TeraGrid News
Architecture
Implementation
Requirements
• Fast and responsive
• Low bandwidth consumption
• Secure
• Modern Web 2.0 Look-And-Feel
Implementation
Solutions
• PHP
• iUI JavaScript library
• jQuery JavaScript library
• SSL
• Authenticated session management
Implementation
Client-side :: public view
• News
• System Status
• Help
• Etc
Implementation
Cross-platform
iPhone
Palm Pre
HTC Hero (Android)
Implementation
Client-side :: authenticated view
• My TeraGrid section
– User profile
– Allocations
– Accounts
– Jobs
Implementation
Active user jobs listing
Detailed job and
Notification page
User profile page
Implementation
Server-side :: public information
• News: cached TeraGrid News RSS feed, page
scraping for full text
• System status: GPIR, Inca
Implementation
Server-side :: authenticated information
• Profile, account, and allocation info: User Profile
service
• Jobs
– Running/Queued/Pending: cached MDS job info
• Note: not available at every site
– Finished: TGCDB
• Note: very costly query
• Job notifications: job registry and cron trigger
service
Implementation
Server-side :: background processes
• System info: queries GPIR and caches to disk
• Batch queue query: copies cached MDS queue
info from IIS.
• Trigger processing: runs after batch queue
query and processes relevant job notifications.
Implementation
Server-side :: auditing
• Log everything to disk
• Roll logs monthly
• Run analytics script on log files for usage info.
Community Acceptance
• Roughly 2000 hits/month
• News, System Status, and Job info are most
popular pages.
• Still advertising TGUP Mobile to the
community.
Future Work
• Consulting ticket support
• Managing training class registrations
• TeraGrid file management through virtual
home space
• Integrating Resource Discovery Service
• Integrating RESTful downtime service
