Introduction to Code Parallelization using OpenMP
Instructor: Marinus Pennings
Time: Friday, April 3, 10:00AM-12:30PM
Location: Zoom session only
Prerequisites: Working knowledge of C/C++ or FORTRAN; Intro to Linux or Unix/Linux skills; Ada account.
This course covers code parallelization on shared memory systems using the OpenMP standard. We will start with a brief discussion about basic hardware architecture and compiling and running OpenMP program. Next we will introduce the OpenMP programming model and we will discuss OpenMP directives, library functions and environmental variables. The course is example driven (Fortran90 and C++ code snippets) to explain the various concepts and there are a few demo problems we will do together in class.
The presentation slides are available as downloadable PDF files.
This course focuses, among others, on the following topics:
- Basic Architectural overview
- Shared memory parallelization concepts
- Compiling and running OMP programs
- Structure of OpenMP directives/pragmas
- OpenMP Work sharing constructs
- Synchronization directives/pragmas
Note: During the class sessions many aspects of the material will be illustrated live via a login to Ada. Attendees are welcome to follow these parts with their own laptops. They will need to configure their laptops to use the TAMULink wireless network. Relevant details on this can be found at: http://tamulink.tamu.edu/
You are encouraged to contact the HPRC helpdesk with any questions regarding Ada.
