Dev. Preview for TG09

Gadgets, Open Social Portals

Open Social containers, gadgets, OAuth, OpenID

SVN, will build

Incubator projects

Pylons portals, metascheduling services, bio-gadgets, etc.

SVN if you dare

Tutorial will focus on the bold-faced items.

OGCE and Gateways We develop and package software for use by TeraGrid

Science Gateways and other resources BioVLAB use OGCE tools to run on Amazon

A lot of this comes from active Gateways. Information Services (GPIR, QBETS): TeraGrid User Portal Workflow tools: LEAD Resource Discovery Service, File Browser Applet: TGUP,

GridChem SIDGrid, OLSG

We contribute codes back to these projects.

Decorate with bridge and container jars, xml config files.

GTLAB gadgets can also run as portlets with no code changes by using the JSF portlet bridge.

GTLAB MyProxy Example<h:form id="form"> <h:outputText value="Username:"/> <h:inputText value="#{resource.username}" required="true"/>

<h:outputText value="Password: "/> <h:inputSecret value="#{resource.password}" required="true"/>

<h:outputText value="MyProxy Server: "/> <h:inputText value="#{resource.myproxyHostname}" required="true"/>

<o:submit id="submit" value="Submit" binding="#{builder.body}" action="#{builder.junkAction}" >

<o:multitask id="multi" persistent="true" taskname="#{resource.taskname}"> <o:myproxy id="mypr" hostname="#{resource.myproxyHostname}"

lifetime="2" password="#{resource.password}" port="7512"

username="#{resource.username}"/> </o:multitask> </o:submit> </h:form>

Packaging, Building and Testing

All builds are designed to be self contained Use Apache Maven 2.0Download includes everything you need.

Portal, Axis Services, and Xregistry all build nightly on the NMI Build and Test facility at UW.17 Linux platforms, Mac PPC, and Mac X86 Java 1.5

Apache JMeter test suite for the portal. Run against your installationAutomated tests nightly

JMeter test suite

OGCE Portal

Components for Science Portals

OGCE is founded on the principal that portals should be built out of reusable parts.

Key standard in our first phase: the JSR 168 portlet specification.

Portlets can run in multiple containersuPortal, Sakai, GridSphere, LifeRay, etc.

Allows us to build Grid specific components and deploy along side third party componentsSakai collaboration tools, RSS feed readers,

contributed portlets, etc.

Future (?): Open Social compliant Google GadgetsFacebook apps

Downloading and Installing OGCE Portal Software

You can have a basic portal up and running in a few minutes.

Installation process:Update properties in pom.xml to match

your Grid.Run “mvn clean install”That’s it

OGCE GPIR portlet can interoperate with TeraGrid and your own GPIR

services.

Manage TeraGrid MyProxy credentials with the OGCE

ProxyManager portlets.

OGCE file management client portlets interact with TeraGrid

GridFTP servers.

General purpose batch and interactive job submission to GRAM, WS-GRAM is supported.

Dashboard Portlet

19

Check on your jobs with a simple dashboard portlet.

Queue forecasting portlets work with the NWS QBETS to predict wait times and deadlines.

Condor and Condor-G

OGCE IFrame Portlet can be used to integrate external

sites.

Under the Hood: Building Components

Portlets can be built with our Apache Velocity bridge.Still some interest in this.“Template” or “steal this code” approach.

OGCE portlets use the Java COG Abstraction Layer to access Grid services.Provides a buffer over different Grid toolkits and

versions.Provides ability to compose graph-based workflows.Tutorial in itself

We have also developed Grid Tag Libraries and Beans (GTLAB) to simplify development process.

Some OGCE ServicesInformation Web Services and build framework

Resource Discovery Service

Extracted from the TeraGrid User PortalContributed by Rion Dooley, TACC

Axis2 Web service

Integrates information from INCA, GPIR services.What machines are in my GridWhich ones are actually running?

Works with TeraGrid deployed services, but you can use it with your own information service installations.

Resource Prediction Service (RPS)

• Predicts an optimal set of resources for running scientific applications– Predicts a set of resources on which the sum of data

transfer time, queue wait time and compute time for the application will be minimum

– Data transfer time: Uses input data size and NWS info

– Queue wait time: Uses QBETS info– Compute time: Uses application performance info

• Axis2 web service with a MySQL backend

• RPS is a subset of the Fault Tolerance and Recovery service used in LEAD and VGrADS

Packaging ServicesEverything builds with one command

mvn clean install

We use Apache Maven 2 for builds.Structured, modular builds and consistent layouts

Build a single module: mvn clean install –f somemod/pom.xml

We include Apache Tomcat in the download, so all you need is Java and MySQL.

Suitable also for the NMI build and test system.

Want the Javadoc? mvn javadoc:javadoc

Upcoming Services

XMC-CAT metadata cataloging service with JSDL sample implementation.See also our demo on Wednesday.

Swarm Web Service for mass job submission and management.http://escience2008.iu.edu/sessions/SWARM.shtml

GPIR Web Service for information on your Grid. This is being repackaged; older packaged version (but same code) is already available.

Workflow suite services will be integrated in the future.
