Installing Nektar++ on OS X through MacPorts or Homebrew

Installing Nektar++ on OS X through MacPorts or Homebrew
This post briefly summarises how to install Nektar++ using either the MacPorts or Homebrew package managers. Both of these install a version of Nektar++ that includes MPI for parallel execution, ARPACK for stability analysis, FFTW for homogeneous expansions, PETSc support and a full set of solvers. They can also both be used to install development versions of Nektar++.

An adaptable parallel algorithm for the direct numerical simulation of incompressible turbulent flows using a Fourier spectral/hp element method and MPI virtual topologies

An adaptable parallel algorithm for the direct numerical simulation of incompressible turbulent flows using a Fourier spectral/hp element method and MPI virtual topologies
DOI: 10.1016/j.cpc.2016.04.011
Abstract: A hybrid parallelisation technique for distributed memory systems is investigated for a coupled Fourier-spectral/hp element discretisation of domains characterised by geometric homogeneity in one or more directions.

Nektar++ on the Mira Cluster

Mira is a Blue Gene/Q supercomputer ran by the Argonne national laboratory. As of 2016, it is ranked as the fifth-fastest supercomputer in the world. If you are interested in using Nektar++ on Mira, please read on. Users of Mira often have access to Cetus, a smaller  cluster with the same architecture as Mira. The […]
