  We investigate the spectral properties of plasma turbulence from fluid to
sub-ion scales by means of high-resolution three-dimensional (3D) numerical
simulations performed with the hybrid particle-in-cell (HPIC) code CAMELIA. We
produce extended turbulent spectra with well-defined power laws for the
magnetic, ion bulk velocity, density, and electric fluctuations. The present
results are in good agreement with previous two-dimensional (2D) HPIC
simulations, especially in the kinetic range of scales, and reproduce several
features observed in solar wind spectra. By providing scaling tests on many
different architectures and convergence studies, we prove CAMELIA to represent
a very efficient, accurate and reliable tool for investigating the develpoment
of the turbulent cascade in the solar wind, being able to cover simultaneously
several decades in wavenumber, also in 3D.
