ADT SPETABARU-H

Participants : Bérenger Bramas, Vincent Loechner, Paul Cardosi.

Duration: 2019 - 2021

The SPETABARU task-based runtime system is now being developed in CAMUS. This tool is the first runtime system build on the tasks and dependencies paradigm that supports speculative execution. It is at the same time a robust runtime system that could be used for high-performance applications, and the central component to perform research in parallelization, speculation and scheduling.

The SPETABARU-H project started in November 2019 for 2 years aims in improving SPETABARU on several aspects:

• Implement a generic speculative execution model based on the team's research;

• Implement the mechanisms to make SPETABARU supporting GPUs (and heterogeneous computing nodes in general);

• Split the management of the workers and the management of the graph of tasks to allow multiple independent graphs to be used on a single node;

• Use SPETABARU in the Complexes++ application, which is a bio-physic software for protein simulation;

• Maintain and update the code to keep it modern and up to date.

Idex Prim'Eau

Participant : Jens Gustedt [contact] .

In the framework of the Prim'Eau project of the University of Strasbourg, we study surface runoff for hydrological periods of several days. We use an efficient domain decomposition method that we apply to a real world example of Mutterbach (Moselle) with geological and flood data from the years 1920, 1940 and 2017. As the time and memory usage for these computations is important, we aim to parallelize them.
