Open Grid Computing Environments: Advanced

Gateway Support Activities

RT Project ReviewOctober 7th, 2010

Software Description

OGCE Gadget Container

Google Gadget/Open Social compatible software for building Web-based user interfaces.

XBaya A visual user interface for composing, launching and monitoring workflows

GFAC An application factory service for wrapping command-line tools as Web services

XRegistry A service and workflow registry

Registry Gadget, Experiment Builder

User interface for registering services and creating online experiments with registered workflows

Software Strategy• We develop and package downloadable software• Focus on gadget container and tools for running

science applications on grids and clouds.• Provide a tool set that can be used in whole or in

part.– If you just want GFac, then you can use it without

buying an entire framework.• Outsource security, information services, data

and metadata, etc to other providers.– MyProxy, TG IIS, Globus, Condor, XMC Cat, iRods, etc.

• NCSA/UIUC: Sudhakar Pamidighantam (Co-PI), Shaowen Wang, Yan Liu

• UTHSCSA: Emre Brookes (Co-PI), Borries Demeler

Project Highlights• Full Circle Development

– Directly fund both software developers and gateway consumers.

• Directly supported (non-IU) gateways: – UltraScan (UTHSCSA), GridChem (NCSA),

SimpleGrid/GISolve (UIUC), Purdue CCSM and Environmental Data Gateways

– Among the most used TG gateways.• Sustainability strategy: Apache Incubator for

workflow suite of tools – XBaya, GFac, and supporting services.

UltraScan High Level Overview

UltraScan Middleware

• Immediate Goals: Use GFAC as a replacement job submission service. – GRAM 2, 4, 5 independence– Significant effort into GRAM5

testing on Ranger.• Longer term goals

– Integrate with TG information services to provide better job scheduling.

• OGCE Resource Prediction Service– Support UNICORE job

management. Current Architecture

Gram5 Testing Steps• Developed Testing harness to run different

UltraScan cases.• Started with small number of jobs and increased

the concurrency later• Watched job behavior of the job on resource and

monitored the gram log– There were lot of issue which we found from

the logs and working with Globus team to fix them

• Recorded all the job run data to create a google gadget to create graph for different runs on different resources.

• There were problems with Sun Grid Engine job manager (sge.pm) not loading system environment and user environment settings.

• You can't load modules using Gram parameters. – On Ranger all the libraries are modules and user may want to load

some special module version for his job. – Example is if you have different version of your code using different

modules.

• On Ranger user default shell is C shell and Gram runs using bash shell. This is not a problem but users need to be informed where to add user environment.

• You can look at detailed results on followinghttp://teragridforum.org/mediawiki/index.php?title=GRAM_5_Testing

Learning from this exercise on Ranger

GridChem Science Gateway• A chemistry/material Science Gateway for running

computational chemistry codes, workflows, and parameter sweeps.

• Integrates molecular science applications and tools for community use.

• 400+ users heavily using TeraGrid. One of the consistent top5 TeraGrid Gateway users.

• Supports all popular Chemistry applications including Gaussian, GAMESS, NWChem, QMCPack, Amber and MolPro, CHARMM

• ParamChem is a follow-on project to develop workflows for chemical parameter studies and provide the infrastructure to execute them.

Cyberenvironments for ParameterizationComputational Reference Data Generation

GridChem , ParamChem Integration

• Immediate Goals: integrate XBaya workflow composer with GridChem user interface and middleware.– Target SC10

• Longer term goals: provide part of GridChem next generation middleware; support large scale ParamChem workflows.

SimpleGrid (UIUC)

SimpleGrid is a Gateway teaching tool that is also the core of GISolve

SimpleGrid Gadgets

Yan and Gerald’s work from our Oct 6th hacking session.

SimpleGrid, GISolve

• Short term goal: develop SimpleGrid Gadgets deployable into gadget container.– Must meet security requirements– Support PHP development– Support interactivity requirements

• Integrate YUI JavaScript libraries with Gadget JavaScript.

• Longer term goals: investigate workflow, job management tools. Apply to GISolve

Purdue CCSM and Data Portals

• Short terms goals: Develop CCSM and data management gadgets and necessary backing middleware.– Support GWT development– Interactivity and security requirements.– Significant requirements overlap with SimpleGrid

• Longer term goals: Build gateways out of gadgets hosted by multiple containers; examine workflow and other tools.

Conclusion• We focus initially on one component per

gateway.– SimpleGrid, CCSM, Data Portal: gadgets

• Other gadget based gateways at UC– GridChem: Xbaya– UltraScan: GFac

• Goal is to establish an Apache-style meritocracy for contributed code.

• Making distributed teams work: hacking retreats, SourceForge, Jira, Google apps

Putting It All Together

Software Strategy

• Focus on gadget container and tools for running science applications on grids and clouds.

• Provide a tool set that can be used in whole or in part.– If you just want GFac, then you can use it without

buying an entire framework.

• Outsource security, information services, data and metadata, etc to other providers.– MyProxy, TG IIS, Globus, Condor, XMC Cat, iRods, etc.

Advanced Support Scenarios

• GridChem/ParamChem workflow support• UltraScan Job Submission (GFAC)• EST Pipeline

– Bioinformatics pipeline for managing mass job submission.

More Information• This is downloadable, packaged software.

– Apache Maven build system provides everything you need to to build the gadget container, gadgets, workflow composer, and backing services.
