Space Weather Prediction and Exascale Computing
Found in: Computing in Science & Engineering
By Giovanni Lapenta,Stefano Markidis,Stefaan Poedts,Dean Vucinic
Issue Date:September 2013
pp. 68-76
Space weather can have a great effect on Earth's climate. Predicting the impact of space environment disturbances on Earth presents a challenge to scientists. The authors present the ExaScience Lab's efforts, which use exascale computing and new visualizat...
On the scalability of the clusters-booster concept: a critical assessment of the DEEP architecture
Found in: Proceedings of the Future HPC Systems: the Challenges of Power-Constrained Performance (FutureHPC '12)
By Damian Alvarez Mallon, Estela Suarez, Giovanni Lapenta, Maria Elena Innocenti, Norbert Eicker, Thomas Lippert
Issue Date:June 2012
pp. 1-10
Cluster computers are dominating high performance computing (HPC) today. The success of this architecture is based on the fact that it proffits from the improvements provided by mainstream computing well known under the label of Moore's law. But trying to ...
