1. Overview


  • is a code framework, rather than just another MHD/HD code
  • is a system for task based computing with, in principle, unlimited scaling
  • supports different kinds of (co-existing) tasks (e.g., cell-, ray- & particle-based), using HD, MHD, RMHD, non-ideal MHD, and / or particle-in-cell solvers
  • can support and boost the performance of both existing and new solvers
  • relieves solvers from dealing with MPI communication and OpenMP parallelization
  • makes it trivial to implent new solvers, which are required to perform only two tasks:
    1. choose a time step size, based on local variables
    2. update its state, given guard cell or other neighbor information, provided by the framework
