Full Day tutorials (8:30am-5:00pm)

TeraGrid Institute: User Introduction to TeraGrid
The Teragrid (TG) user support team will present an introduction to the TG resources, how to apply for a TG grant, how to use the TG User Portal as a single resource and information access point, and sample usage scenarios.

Globus for the TeraGrid
In this tutorial we will give an overview of the basic components of Globus (core, security, data management, execution management, information services) from an architectural point of view, discuss use cases in the TeraGrid, and any adaptations made for TeraGrid, discuss the use of Globus information available through the portal, and other aspects.

TeraGrid Visualization Workshop
The TeraGrid Visualization workshop will start with an overview of the analysis resources and services available through TeraGrid and will explore how to best utilize these resources. Additionally, we will cover the tools and services that are best suited to your data exploration and visualization needs.

Building Blocks for a Simple TeraGrid Science Gateway
This tutorial will provide instruction to those planning to build a science gateway. The tutorial will cover topics including gateway design, technology selection, usability issues, and when and how to access more powerful resources. Also included will be a TeraGrid resource and services overview.

Using Condor
This tutorial will present a synopsis on using Condor for high- throughput computing. It will present the basics of Condor, its capabilities and related functionality such as Condor-G and DAGman, discuss applications well suited for Condor and the Purdue TG Condor pool, and provide an opportunity for hands-on access to Condor at Purdue.

Half Day tutorials – Morning (8:30am-noon)

Logging into the TeraGrid: User authentication for the TeraGrid Portal, SSH sessions, grid services, and unattended jobs
This tutorial will guide users through use of new, easier access methods and authentication details. Examples of common TeraGrid authentication issues and solutions will be presented. In addition, the tutorial will cover advanced credential management methods used to sustain access to TeraGrid resources during long-running user applications.

Gateway to the TeraGrid for Bio-Scientists: A Tutorial. What does it do? How is it used in course curricula? How was it constructed?
This tutorial will have three specific areas of focus: description of the capabilities of the portal; description of experiences using this platform as part of course curricula for college; and description of construction of the portal.

Introduction to IU's Big Red PowerPC Cluster and IU storage resources via the TeraGrid
The primary purpose of this tutorial is to enable existing and new TeraGrid users to learn about the Big Red system (IBM e1350 cluster) so that they can easily use codes already ported and optimized for that system (e.g. WRF, NAMD, MILC) or rapidly migrate other existing applications to Big Red so as to accelerate scientific discovery.

Swift: Fast, Reliable, Loosely Coupled Parallel Computation
You need to run an analysis pipeline on a thousand functional magnetic resonance imaging (fMRI) files. The files are in some funny directory structure, the TeraGrid is miles away, and neither writing an MPI program nor performing the many analysis tasks manually is attractive. Swift addresses such challenges. A few lines of SwiftScript describe how your analysis procedures should be applied to the many fMRI images. Swift tools dispatch the thousands of tasks to TeraGrid nodes. Your computation is performed quickly and reliably, and the results are documented with data about how they were computed. Life is good.

Half Day tutorials – Afternoon (1:30pm-5:00pm)

Rule-Oriented Data Management
This tutorial describes the next generation of data management systems, as represented by the integrated Rule-Oriented Data System (iRODS), the creation of management policies, and the automated execution of the management policies.

Using nanoHUB.org as a Science Gateway
nanoHUB.org is the Nanoscience Gateway for the TeraGrid. In 2006, more than 19,000 people accessed nanoHUB to view seminars, tutorials, animations, homework assignments, and most importantly, to run nanotechnology simulations. The middleware powering the nanoHUB can launch tool sessions on virtual machines in the nanoHUB cluster. Users can access these tool sessions from any Web browser. Pressing the Simulate button on the tools graphical interface launches a job on the nanoHUBs local cluster or sends the job to more powerful computing resources, including Violin virtual clusters and TeraGrid resources. In 2006, more than 4,200 users from all over the world launched over 142,000 simulation jobs. This tutorial will demonstrate the various simulation resources available through nanoHUB, including TeraGrid access through nanoHUB tools and workspaces.

Best Practices for Data Transport on the TeraGrid
The TeraGrid Data Working Group addressed data transfer challenges observed for TeraGrid users, and planned for future TeraGrid data services. Among the needs identified were instructional materials and tutorials regarding current best practices for TeraGrid users regarding methods for reliable and efficient data transfer of large volumes of data to, from and between TeraGrid data storage resources, including computing systems, file systems and archives. This tutorial serves to address these needs in part with presentations, demonstrations and examples of current best practices for large volume data transfers using GridFTP, RFT, and related data transfer methods.

Pegasus and DAGMan Tutorial
Pegasus is a workflow planner for the grid. Pegasus maps high-level workflow descriptions onto the available cyberinfrastructure resources and produces an executable workflow. DAGMan is a production quality workflow executor developed as part of the Condor project that executes the workflow created by Pegasus by performing dependency analysis and releasing workflow jobs to the grid as and when they are ready for execution. This tutorial will cover the basics of workflow creation, planning, and execution.
