  1. 278. Lecture: MPI Basics
    Lilit Axner (PDC - Center for High-Performance Computing)
    23/08/2010, 09:15
    Parallel Programming
    This lecture gives you an overview of MPI functionality and discuss the value of having a standard message passing library. It provides a tailored tour of the basic concepts and mechanisms that will be of most value to you as beginning MPI programmers. This includes gaining a familiarity with some of the most commonly used MPI calls, the way in which MPI is initialized and...

  2. 279. Lecture: MPI Point-to-Point Communications I
    Lilit Axner (PDC - Center for High-Performance Computing)
    23/08/2010, 10:15
    Parallel Programming
    In point to point communication, one process sends a message and a second process receives it. This is in contrast to collective communication routines, in which a pattern of communication is established amongst a group of processes. This lecture will cover the different types of send and receive routines available for point to point communication.

    Lilit Axner (PDC - Center for High-Performance Computing)
    24/08/2010, 08:30
    Parallel Programming
    During this question and answer period, we will discuss questions that came up from yesterday's lectures and labs on MPI Basics and Point-to-Point Communication.

  6. 283. Lecture: MPI Point-to-Point Communications II
    Michaela Lechner (PDC - Center for High-Performance Computing)
    24/08/2010, 09:15
    Parallel Programming
    MPI Point to Point Communication I introduced many of the routines related to sending a message between two processes, with a focus on programming with blocking and non-blocking routines. This lecture will discuss another important area: communication mode. Choosing a communication mode gives the programmer some control over how the system handles the message and can improve...

  7. 284. Lecture: MPI Collective Communications
    Michaela Lechner (PDC - Center for High-Performance Computing)
    24/08/2010, 10:15
    Parallel Programming
    There are certain communication patterns that appear in many different types of applications. Rather than requiring each programmer to code these using point to point communication, MPI provides routines that handle these patterns for you, called collective communication routines. This lecture will survey these routines, the communication pattern established, and their syntax.

  11. 296. Lecture: MPI Hybrid (MPI+OpenMP)
    Olav Vahtras (PDC - Center for High-Performance Computing)
    26/08/2010, 09:15
    Parallel Programming
    When OpenMP is used in conjunction with the Message Passing Interface (MPI), the result can provide a second level of parallelism which has the possibility to gain the greater efficiency on clusters of SMP nodes. In this lecture, we will show how to do such hybird programming by using examples.

    Olav Vahtras (PDC - Center for High-Performance Computing)
    26/08/2010, 13:15
    Parallel Programming
    In this lab exercise, you will parallelize some simple algorithms using shared memory programming (OpenMP) and distributed memory programming (MPI) simultaneously.

  15. 300. Lecture: MPI Virtual Topologies
    Olav Vahtras (PDC - Center for High-Performance Computing)
    27/08/2010, 09:15
    Parallel Programming
    A virtual topology is a mechanism for naming the processes in an MPI communicator in a way that fits the communication pattern better. In this lecture we cover the basic concept behind virtual topologies, the main MPI calls used to achieve it, and some examples.
