This version brings two majors changes to FBPIC: The code now supports multi-threading on CPU (when using numba>=0.34), and is therefore much faster then it used to be on multi-core CPU architectures. The code does not rely on the proprietary library accelerate anymore, and uses the open-source library pyculib instead. As a consequence, all the dependencies of FBPIC are now open-source. In addition to these changes, several minor improvements have been made to the GPU code, including faster sorting routines (prefix_sum) and shorter compilation time (function signatures have been removed).
