Description

This release introduces an important change on GPU: FBPIC now uses the cupy package instead of the pyculib package (since pyculib is no longer supported); see #356 #363 #367. As a result, it is now possible to use FBPIC with Numba 0.43 (or higher).

It also introduces official support for MPI-decomposed simulation ; see #348

In addition, this release adds various improvements to FBPIC:

New features:

  • FBPIC can now initialize beams with arbitrary charge #364
  • The external fields can be automatically transformed to the boosted frame #342
  • The ParticleChargeDiagnostic is now smoothed, in the same way as the regular charge density diagnostic #349

Optimizations:

  • The number of threads per block were optimized for modern GPUs #365
  • Certain arrays are now kept on GPU, and never copied to CPU #361

Bug-fix:

  • There was a bug when restarting a simulation involving ionization on GPU #360
