DescriptionLegion is a programming model designed for portable,
scalable and high performance applications on
contemporary and future supercomputers. In this
tutorial, participants will be introduced to Regent, a
high-level programming language for the Legion
programming model. The tutorial will be organized around
teaching Regent “from the ground up”, beginning with the
motivation for task-based programming, simple examples
and hands-on exercises, and working up to advanced
programming concepts. The examples and exercises using
Regent will allow participants to progress quickly from
being introduced to the basics of task-based programming
to writing parts of and thoroughly understanding a
non-trivial, self-contained Regent application at the
end of the tutorial. The cloud-based exercises will
allow participants to run experiments on a cluster of
multicore machines with GPUs. Tools for visualizing the
functional behavior and performance of Regent
applications will show participants the effect of
different choices in mapping tasks and data onto complex
machines. Overall, the tutorial will provide
participants with an overview of task-based programming
and performance tuning, as well as a starting point for
developing their own task-based applications.
