piccante is a massively parallel fully-relativistic electromagnetic 3D particle-in-cell code, released by the authors to the whole laser-plasma community under a GPLv3 license.
Its strengths are related to flexibility: the user is able to define an arbitrary number of particle species with arbitrary density functions and an arbitrary number of Gaussian laser pulses.
The code is proved to scale very well up to 32768 MPI processes.
In its present state, the code could be considered in beta status.
