Distributed memory parallelization with the Message Passing Interface MPI (Mon, for beginners):
On clusters and distributed memory architectures, parallel programming with the Message Passing Interface (MPI) is the dominating programming model. The course gives an introduction into MPI-1. Hands-on sessions (in C and Fortran) will allow users to immediately test and understand the basic constructs of the Message Passing Interface (MPI).
Shared memory parallelization with OpenMP (Tue, for beginners): The focus is on shared memory parallelization with OpenMP, the key concept on hyper-threading, dual-core, multi-core, shared memory, and ccNUMA platforms. This course teaches shared memory OpenMP parallelization. Hands-on sessions (in C and Fortran) will allow users to immediately test and understand the directives and other interfaces of OpenMP. Race-condition debugging tools are also presented.
Intermediate and advanced topics in parallel programming (Wed-Fri): Topics are advanced usage of communicators and virtual topologies, one-sided communication, derived datatypes, MPI-2 parallel file I/O, hybrid mixed model MPI+OpenMP parallelization, parallelization of explicit and implicit solvers and of particle based applications, parallel numerics and libraries, and parallelization with PETSc. MPI-3.0 introduced a new shared memory programming interface, which can be combined with MPI message passing and remote memory access on the cluster interconnect. It can be used for direct neighbor accesses similar to OpenMP or for direct halo copies, and enables new hybrid programming models. These models are compared in the hybrid mixed model MPI+OpenMP parallelization session with various hybrid MPI+OpenMP approaches and pure MPI. Further aspects are domain decomposition, load balancing, and debugging. Hands-on sessions are included on all days. This course provides scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.

Unix / C or Fortran. For days 3-5, the first two beginners days or equivalent knowledge is required. If you register only for days 3-5, we reserve the right to send you a small test to check whether such participation on only days 3-5 is possible.
To be able to do the hands-on exercises of this course, you need a computer with an OpenMP capable C/C++ or Fortran compiler and a corresponding, up-to-date MPI library (in case of Fortran, the mpi_f08 module is required). Please note that the course organizers will not grant you access to an HPC system nor any other compute environment. Therefore, please make sure to have a functioning working environment / access to an HPC cluster prior to the course. In case of questions, please contact the course organizer (see below).
In addition, you can perform most MPI exercises in Python with mpi4py + numpy (this contribution has been initially supported by the Horizon-2020 Centre of Excellence HiDALGO at HLRS). In this case, an appropriate installation on your system is required (together with a C/C++ or Fortran installation for the other exercises).
Please tar -xvzf TEST.tar.gz using https://fs.hlrs.de/projects/par/events/TEST.tar.gz or unzip TEST.zip using https://fs.hlrs.de/projects/par/events/TEST.zip and verify your MPI and OpenMP installation with the tests described in TEST/README.txt within the archive.

HLRS is part of the Gauss Centre for Supercomputing (GCS), which is one of the six PRACE Advanced Training Centres (PATCs) that started in Feb. 2012. A part of this course is a PATC course (tbc), see also the PRACE Training Portal and Events. For participants from public research institutions in PRACE countries, the course fee is sponsored for this part of the course through the PRACE PATC program. For details, see the section about the course fee above.
HLRS is also member of the Baden-Württemberg initiative bwHPC-C5. This course is provided within the framework of the bwHPC-C5 user Support.
In conjunction with this course, a Train the Trainer Program is provided. Whereas this regular course teaches parallel programming, the Train the Trainer Program is an education for future trainers in parallel programming. For further details, see here.
