Developing and tuning computational science applications to run on extreme scale systems
are increasingly complicated processes. Challenges such as managing memory access and …

A significant percentage of the computing capacity of large-scale platforms is wasted
because of interferences incurred by multiple applications that access a shared parallel file …

A new atmospheric general circulation model (dynamical core) based on the discontinuous
Galerkin (DG) method is developed. This model is conservative, high-order accurate and …

The main mechanisms for the initiation and propagation of the Madden‐Julian Oscillation
(MJO) are still widely debated. The capacity of operational global climate models (GCMs) to …

In large-eddy simulations (LES), it is crucial to ensure that discretization errors do not
contaminate the subgrid effect of the turbulence model in a wavelength range larger than the …

With the ever-growing need of data in HPC applications, the congestion at the I/O level
becomes critical in super-computers. Architectural enhancement such as burst-buffers and …

It has been recently demonstrated that stratiform heating plays a critical role in the scale-
selection of organized tropical convection, in an aquaplanet version of a coarse-resolution …
