Full Changelog: 0.24.0...0.25.0

0.24.0

This version adds the option to symmetrize a Gaussian beam, so as to avoid random fluctuations in the mean transverse position of the beam. (See 642)

0.23.0

• FBPIC can now be used with numba 0.57 on GPU (See 640)
• FBPIC now supports tracer particles (See 630)
• FBPIC is now compatible with PICMI's new ionization interface (See 631)

0.21.0

This release expands support for the PICMI interface, in particular for boosted-frame simulations. In addition, this release added the new optional argument boost_positions_in_dens_func to the function add_new_species.
This allows the pass the density function directly in the lab frame. (See 463)

0.20.4

This is a bug-fix release. It fixes an issue when using GPU Direct with mpi4py version 4 and above (See #565).

In addition, the internal implementation of the laser profiles has been refactored. (See #560, #561, #562). However, the user interface is unchanged.

0.20.3

This is a bug-fix release. It improves FBPIC's compatibility with recent versions of some of the software dependencies (namely numba and mkl).

• The latest version of numba (numba 0.53.) raised numerous warnings when running previous versions of FBPIC on GPU. These warnings do not appear anymore with this new release. (See #538)

• FBPIC can use the MKL distribution from conda, but was unable to use the MKL distribution from pip. This is now fixed. (See #537)

0.20.2

This is a bug-fix release. It allows FBPIC to run with the latest cupy version (cupy 9.0.0) on GPU (see #532).

0.20.1

This is a bug-fix release. It fixes errors that in detecting the GPU UUID on some plateforms (see #529).

0.20.0

This release introduces several improvements and bug fixes.

Better handling of multiple GPUs on clusters:

• The attribution of individual GPUs to the different MPI ranks is more robust, and avoids oversubscribing certain GPUs while leaving others idle (see #523). In addition, GPU oversubscription is now automatically detected, and a corresponding error message is printed. (see #524)
• Out-of-memory error are handled more properly, and will abort multi-GPU simulations whenever they are encountered by one of the GPUs. (see #521)
• The hostname is now printed even for single-rank simulation. (see #495)
• Kernel launch parameters have been fine-tuned for A100 architecture. (see #525)

Bug fixes:

• The external fields used to be applied to all species, instead of the species specified by the user. This is now fixed. (see #498)
• The installation instructions were updated. (see #515)

New features:

• Added a Mirror class to block the propagation of the laser e.g. in multi-stage simuations. (see #507)
