Currently we expect that we have to cancel this course because one of the trainers may not be able to come. Soon, a final decision will be published on this webpage. (Last modification, Jan. 19, 2018)
The aim of this course is to introduce participants to the HPX library (http://stellar-group.org/libraries/hpx/ and https://github.com/STEllAR-GROUP/hpx and http://stellar-group.org/) and demonstrate how it can be used to write task based programs. The HPX library implements a lightweight threading model that allows both concurrent, asynchronous, parallel and distributed programming constructs to coexist within the same application with a consistent API based on C++ standards and using futures to synchronize between tasks.
The course is aimed at participants with a good understanding of C++. The material covered will include an introduction to the HPX programming model; asynchronous programming concepts, execution policies and executors; parallel algorithms using tasks (including the parallel STL); writing distributed applications with HPX; profiling and debugging and a final section introducing heterogeneous programming using targets for GPU devices.
Objective: The attendee will gain an understanding of the HPX library and task based programming in general.

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. The mandate for the PATCs is as follows: "The PRACE Advanced Training Centres will serve as European hubs of advanced, world-class training for researchers working in the computational sciences." (see D3.2.3)
This course is a PATC course, see also the PRACE Training Portal and Events. For participants from public research institutions in PRACE countries, the course fee is sponsored through the PRACE PATC program.
