  Most periodicity search algorithms used in pulsar astronomy today are highly
efficient and take advantage of multiple CPUs or GPUs. The bottlenecks are
usually represented by the operations that require an informed choice from an
expert eye. A typical case is the presence of radio-frequency interferences in
the data, that often mimic the periodic signals of pulsars, and require visual
inspection of hundreds or thousands of pulsar "candidates" satisfying a number
of preselected criteria. CICLOPS is a citizen science project designed to
transform the search for pulsars into an entertaining 3D video game. We build a
distributed computing platform, running calculations with the user's CPUs and
GPUs and using the unique human abilities in pattern recognition to find the
best candidate pulsations.
