Perl is a powerful and versatile programming language that can be used for a wide variety of programming tasks, including, but not limited to, text/data processing, system administration, and Web applications. Combing elements of C, Unix shell scripting languages, as well as text-processing utilities such as sed and awk, Perl can be used for both large scale projects and for small applications. Some experience in a command line environment (e.g. Unix) is helpful, but the basics of Perl are simpler than those of other languages making it accessible to a new programmer. Attending our Introduction to Linux tutorial or equivalent background is recommended. Please remember to sign up for all four sessions to complete the tutorial.

Wednesday, September 9, 3:30pm – 5:30pm
MATLAB (for MATrix LABoratory) is a numerical computing environment developed by MathWorks, Inc. MATLAB is essentially an interpretive high level language that does not require data type declaration or compilation. It can be used to implement mathematical computations such as matrix manipulations with existing linear algebra packages. Many plotting and visualization tools are available as an integral part of MATLAB. MATLAB operations are very intuitive, user-friendly, and are used primarily in an interactive environment to enable fast proto-typing of research activities and efficient software development. Many highly specialized applications, such as Mathematical Finance, Bioinformatics, and Image Processing, are also available as toolboxes.
In this tutorial, many of the basic MATLAB operations, including basic 2D and 3D graphics, will be introduced. You will learn many of these operations hands-on. No prior programming experience in any languages is required to attend this course.

MATLAB Parallel Computing Toolbox is now available to Boston University’s MATLAB users. This toolbox enables users to solve computationally intensive and data intensive problems on multi‐cored personal computers, laptops, and especially the Shared Computing Cluster (SCC) managed by the Research Computing Services group of Information Services & Technology.
Parallel processing operations such as parallel for‐loops, parallel numerical algorithms, and message‐passing functions let you implement task‐ and data‐parallel algorithms in MATLAB. Converting serial MATLAB applications to parallel MATLAB applications usually requires few code modifications and no programming in a low‐level language.
The prerequisite for this course is a basic knowledge of MATLAB, either developed on your own or from our Introduction to MATLAB tutorial.

The OpenMP and OpenACC application program interfaces (APIs) provide simple and flexible tools to develop parallel software for shared-memory multiprocessor systems and GPU accelerators. The two APIs share a similar basic approach – the programmer inserts directive statements into the code to assist the compiler in mapping computation onto the CPUs or GPUs. The beauty of this approach is that it is often possible to create efficient parallel code with only minor modifications to a serial code. This tutorial covers the major features of the OpenMP and OpenACC through discussion, examples in C and Fortran, and short hands-on exercises.
Prerequisites: This course is for those who are new to parallel programming with OpenMP and OpenACC, but have some experience in C or Fortran programming. Understanding of parallel programming in general is helpful, but not required.
Tuesday, September 29, 1:00pm – 3:00pm
On contemporary computers, speeding up computations is most often achieved by employing multiprocessors concurrently on shared‐memory multi‐cored nodes or multiprocessor distributed‐memory clusters. MPI is a library of communication functions to enable and enhance multiprocessing on these computer architectures. This tutorial introduces many of the basic MPI functions through practical examples. Working knowledge of C or Fortran is required to attend the course. Basic knowledge of Unix/Linux will be helpful. MPI Part Two is a sequel to MPI Part One while MPI Part Three is a hands-on practice session for both MPI Part One and Part Two.
Thursday, October 1, 1:00pm – 3:00pm

In this tutorial we will show you how to get started using Maya. We will teach you the basic workflow for modeling, creating and applying materials, animation, and rendering. We will also cover the basics of importing scientific geometric data and creating high quality renderings and animations from it.
Ordinarily Maya is considered to have a steep learning curve, but in this tutorial we will present a workflow which will provide a sound foundation for pursuing more complex projects.
Note the different location for this tutorial. It will be held at the CAS Computer Lab, 685 Commonwealth Avenue, Room 327.
