The Array Processor Experiment (APE) was an initiative started by the Istituto Nazionale di Fisica Nucleare (INFN) under the guidance of Prof. Nicola Cabibbo and partnered by a number of physics institutions all over Europe.
Since its start in 1984, it has developed four generations of APE custom HPC machines: APE (1986), APE100 (1994), APEmille (1999) and apeNEXT (2005) dedicated to theoretical physics.

Since then, a long journey has been traveled, and several different research lines have been followed. Now, APE is Advanced Physics and Engineering: even when moving from our original path, we still keep in mind what we love and what we care.
