Jérémie Lagravière successfully defended his PhD

On Wednesday, June 24, Jérémie Lagravière successfully defended his PhD "The PGAS Programming Model and Mesh-Based Computation: an HPC Challenge".

Main research findings

When it comes to human health and computing, time is important because life depends on it. Thus having applications that runs fast, very fast, is essential.

However, creating optimized application for complex and powerful hardware is a difficult task that requires huge programming and thinking efforts from programmers and scientists.

In our work, we provide solutions to obtain high performance applied to human heart simulation using the most powerful hardware available while trying to lower the programming effort.

To do so, we have used disruptive programming style (PGAS, Partitioned Global Address Space) and we provide a way to predict obtainable performance.

Before the defence, Jérémie Lagravière presented his trial lecture "Applications of machine learning in optimising compilers".

The PhD defence and trial lecture were fully digital.
