Scope

The aim of the workshop is to bring together people from different disciplines whose research involves the development or application of so-called 'fast Coulomb solvers' - algorithms designed to overcome the O(N2) bottleneck of many-particle systems dominated by classical long-range interactions. These techniques - in particular the fast multipole method, tree codes and advanced mesh-based methods - are becoming increasingly popular in their 'home' research fields, but there are currently few opportunities to exchange ideas and experiences with workers using one of these algorithms in a different scientific context.

The workshop will provide an informal, interdisciplinary forum open to participants from any area of computational science (e.g. astrophysics, physical & quantum chemistry, biophysics, plasma physics or applied mathematics) with an active and/or keen interest in modern 'long-range' methods. The workshop aims to address all aspects of fast N-body algorithms for both static and dynamic problems and will include topics such as:

  • algorithms

    • FMM
    • tree-codes
    • particle-particle/particle-mesh (P3M)
    • particle-mesh-Ewald (PME)
    • multigrid
  • precision/accuracy issues
  • scaling with problem size: O(N) vs. O(NlogN).
  • adaptability: complex geometries; homogeneity
  • benchmarking: algorithm comparison
  • parallelization
