Description

This release adds CPU support, making PIConGPU a many-core, single-source, performance portable PIC code for all kinds of supercomputers. We added particle filters to initialization routines and plugins, allowing fine-grained in situ control of physical observables. All particle plugins now support those filters and can be called multiple times with different settings.

Particle probes and more particle initialization manipulators have been added. A particle merging plugin has been added. The Thomas-Fermi model has been improved, allowing to set empirical cut-offs. PIConGPU input and output (plugins) received initial Python bindings for efficient control and analysis.

User input files have been dramatically simplified. For example, creating the PIConGPU binary from input files for GPU or CPU is now as easy as pic-build -b cuda or pic-build -b omp2b respectively.
