    Perl is a powerful interpreted language that takes very little knowledge to get started. It can be used to automate many research tasks with little effort.


    This tutorial will cover some important properties of Perl and give some examples of simple and useful Perl scripts. We will discuss modules, context, regular expressions, special variables, system calls, and references.

    More and more biological studies involve collection and analysis of three-dimensional images varying over time, often called 4D images. IMARIS is an interactive volume visualization system for 3D and 4D biomedical data.


    This tutorial will introduce users to several features of the IMARIS modules- ImarisTime, Imaris MeasurementPro, and ImarisColoc. It will demonstrate practical applications for image analysis, segmentation, object classification, quantitation, analyze co-localization, and tracking of biological structures in 2D, 3D, and 4D.

    The SAS system is a collection of programs originally designed to perform statistical analysis of data. The SAS software started out in the 1970s as a package for statistical analysis. By the early 1980s SAS had already branched out into graphics and spreadsheets. The SAS system now has a diverse family of products. For example, it includes tools for building interfaces to the World Wide Web and compilers for the C programming language. Most of its products are integrated together and can be used as building blocks to construct a seamless system.


    In this tutorial, we will cover topics such as getting data into the SAS system, summarizing the data, getting started with some basic macro concepts, and using basic statistical procedures.

    The GeneData Expressionist suite is a computational system from GeneData Inc. for analyzing gene expression data from any one- or two-channel microarrays. It consists of three closely integrated modules: Refiner, CoBi, and Analyst (for data quality control, data management, and statistical data analysis).


    This tutorial will cover the main features of each module with some walk-though practice using sample data.

    Insight II is a common user interface for many of the Accelrys modeling, simulation and analysis tools. It can be used graphically or non-graphically. This tutorial covers Insight II as a non-graphical interface and how it can be scripted for modeling and simulation tasks. In addition, participants will learn about Insight II Base Class Library (BCL) programming to develop interfaces within Insight II for other applications.

    Many scientific problems require the optimization of complex functions that have dozens or even thousands of local minima and maxima. Local optimization methods such as Newton-Raphson and its many variants can find nearby local extrema but have little or no chance of finding a global minimum or maximum. Using a genetic algorithm (GA) is often a very efficient means to find a global minimum or maximum for complex functions.


    This tutorial will describe how genetic algorithms work and we will discuss general optimization strategies with GAs. We will also discuss a few GA programs available and how one might parallelize a GA optimization

    Statistics are very important to many scientific research projects. R and S-PLUS are powerful statistical computing environments available at the Supercomputing Institute. Bell Laboratories developed the S language and environment in the 1980s for data analysis. S was further developed into a commercial product called S-PLUS. R is a dialect of the S language.


    This tutorial will demonstrate how to read and manipulate data in the R and S-PLUS environments. In addition, attendees will learn how to perform basic statistical analysis and how to produce graphics with the software packages.

    This one-day workshop on MPI will help researchers write better and portable parallel codes for distributed-memory machines, like Linux clusters. It will focus on basic point-to-point communication and collective communications, which are the most commonly used MPI routines in high-performance scientific computation. In addition, the advantage of using MPI non-blocking communication will be introduced.


    The workshop will combine lecture with hands-on practice. The lecture introduces basic principles, and the hands-on portion focuses on the use of MPI principles via examples.


    Session One: Introduction to basic concepts of "MPI is Small," centering on point-to-point communication.


    Session Two: MPI collective communications including: broadcast, gather, scatter, and Alltoall.


    Programming will be done in Fortran and C, so any background in these two languages will be helpful.

    CHARMM (Chemistry at HARvard Macromolecular Mechanics) is an academically and commercially distributed software for molecular dynamics (MD) simulations. It is used extensively to simulate the dynamic behavior of molecular and biomolecular systems as well as for free energy calculations. This tutorial will cover the fundamental theory of MD simulation and how an MD simulation can be used to study the conformational dynamics of a biomolecular system. This tutorial will also show you how to write command files for doing a simple MD simulation and how to carry out a typical analysis in CHARMM.

    OpenMP is a parallel programming interface for shared memory architectures and is available on the IBM Regatta, IBM SP, and the SGI Altix. For better use of OpenMP programming in high performance computing, the Supercomputing Institute will organize a one-day workshop addressing the different aspects of OpenMP, such as parallel and worksharing constructs, data scope attribute clauses, and synchronization constructs.


    A hands-on practice will follow the lecture. Provided examples will enable the users to insert OpenMP directives for different parallel tasks and data scope attribute clauses. The users are also encouraged to bring in their serial application codes. The User Support Staff members will help you parallelize the code with OpenMP.
