General

  • Multi-bunch intensity handling (beam.ratio: total number of particles/total number of macro-particles)
  • Beam.intensity keeps the total intensity
  • Simon: Pull request for beam addition, everywhere ratio is used now
  • Alex: "full" version of drift to be re-written for alpha only

Simon & Alex: related code

  • LoCa: functions for optimisation
  • Tomo: tomography
  • Impedance toolbox: impedance database
  • CEDAR: data analysis
  • Can we remove part of the duplication?
  • Propose: single toolbox, possible overlaps
  • Discuss it during BLonD meeting

Kostis: Dynamics load balancing for BLonD-MPI

  • Some workers are faster than others
  • Dynamics load balancing to balance computation time to minimise synchronisation time (no waiting for communication)
    • Re-distribution interval dynamically adjusted
  • Task parallelism for tasks that are not necessary to be in order
  • Task parallelism & load balancing to be combined
