These changes have had and will continue to have a major impact on our software. Some of the software and algorithm challenges have already been encountered, such as management of communication and memory hierarchies through a combination of compile--time and...

    The exponential growth of computation is very close to an evolutionary step in the way we use HPC extending and expanding the class of problems they can address. The ongoing digital transformation and software containerization are enabling the use of HPC s in most of the fields of human activities. The new digital hyperconnected world need HPC scientists and not just only Data Scientist.

  19. 11. Finite Element Methods at Realistic Complexities
    Wolfgang Bangerth (Texas A&M)
    2/25/16, 3:45 PM
    Solving realistic, applied problems with the most modern numerical methods introduces many levels of complexity. In particular, one has to think about not just a single method, but a whole collection of algorithms: a single code may utilize fully adaptive, unstructured meshes; nonlinear, globalized solvers; algebraic multigrid and block preconditioners; and do all this on 1,000 processors or...

  20. 12. MHPC Thesis: Hybrid Parallelisation Strategies for Boundary Element Methods
    Mr Nicola Giuliani (MHPC - SISSA)
    2/25/16, 4:25 PM
    Whenever a mathematical problem admits a boundary integral representation, it can be straightforwardly discretised by Boundary Element Methods (BEM). In this work, we present an efficient hybrid parallel solver for FSI problems based on collocation BEM. The major bottlenecks for a serial implementations of BEM is the computational cost and memory requirements needed to respectively assemble...

    Simone Scacchi (UNIMI)
    2/25/16, 5:15 PM
    The complex interaction between the cardiac bioelectrical and mechanical phenomena is modeled by a system of non-linear partial differential equations (PDEs), known as cardiac electro-mechanical coupling (EMC) model. Due to the extremely different spatial and temporal scales of the physical phenomena occurring during a single heartbeat, the discretization of the EMC model with finite elements...

  23. 15. Here and now: the intersection of computational science and computer science
    Nicola Marzari (EPFL)
    2/26/16, 8:45 AM
    Quantum-mechanical simulations have become dominant and widely used tools for scientific discovery and technological advancement; since they are performed without any experimental input or parameter they can streamline, accelerate, or replace actual physical experiments. This is a far-reaching paradigm shift, substituting the cost- and time-scaling of brick-and-mortar facilities, equipment,...

    Marco Borelli (MHPC - SISSA)
    2/26/16, 9:45 AM
    We developed a parallel implementation of the “Density Peak” clustering algorithm, exploiting C++11, OpenMP and the FLANN library for k-nearest-neighbour search. The modified algorithm is approximately 50 times faster than the original version on datasets with half a million points, and scales almost linearly with the dataset size. Thanks to improvements on the density estimation and...

    Multicenter numerical integration scheme for polyatomic molecules has been implemented as an initial step to develop a complete basis-set-free Hartree-Fock (HF) software. The validation of the integration scheme includes the integration of the total density and the calculation of Coulomb potentials for several diatomic molecules. A finite difference method is used to solve Poisson's equation...

    Volker Springel (The Heidelberg Institute for Theoretical Studies)
    2/26/16, 10:45 AM
    Numerical simulations on supercomputers play an ever more important role in astrophysics. They have become the tool of choice to predict the non-linear outcome of the initial conditions left behind by the Big Bang, providing crucial tests of cosmological theories. However, the problem of galaxy and star formation confronts us with a staggering multi-physics complexity and an enormous dynamic...
