SUMMARY:Nektar++: an open-source spectral/hp element frameworks - Chris Ca

DESCRIPTION:The spectral/hp element method combines the geometric flexibil
 ity of traditional low-order finite element methods\, with the performance
  advantages of pure spectral techniques. The price of these benefits is in
 creased implementational complexity and challenges in consistently obtaini
 ng good performance across the richer space of discretisations and hardwar
 e architectures. Nektar++ is a framework designed with the goal of address
 ing these challenges and enabling the use of these otherwise complex metho
 ds by a range of application scientists and industrial users.\n\nIn this t
 alk\, motivated by a range of example problems\, I will give an overview o
 f the design of the framework and some of the implementation choices made.
  I will discuss some recent algorithmic advances in the library and our jo
 urney towards achieving scalable performance across a broad range of polyn
 omial orders and element shapes. Finally\, I will also touch on the growth
  of a community around the framework and our development practices which w
 e depend on to make Nektar++ a successful  software project.
