Exascale Computing – Architectures and Parallel Programming Techniques
Nowadays, the most powerful supercomputers in the world, needed for solving complex models and
simulations of critical scientific problems, are able to perform tens of PetaFLOPS (1015).
Although such a big amount of computational power may seem enough, scientists and engineers
always need to solve more accurate models, run broader simulations and analyze huge amount of
data in less time. In particular, experiments that are currently impossible, dangerous, or too
expensive to be realized, can be accurately simulated by solving complex predictive models
on an exascale machine (1018 FLOPS).
Unfortunately, because of the high energy requirements, building an exascale system with the
technology we currently use on petascale machines would represent an unaffordable project.
Deep changes in computer architectures and parallel programming techniques are already
happening and people involved in High Performance Computing will be compelled to change the
way they write parallel software.
This talk, composed by two parts, first introduces the audience to exascale computing, showing the
architectural trends and the most revolutionary changes compared to the current architectures. Then,
it proposes and analyzes the potential benefits of Partitioned Global Address Space (PGAS)
languages on exascale machines, showing practical programming examples.
Seguirà tavola rotonda con il Prof. Beniamino Di Martino.
