High Productivity Computing Systems (HPCS) is a DARPA project for developing a new generation of economically viable high productivity computing systems for national security and industry in the 2002–10 timeframe; an extenuated research specialization that's from High-Performance Computing Systems.
The HPC Challenge (High-performance computers challenge) is part of the project. An HPCS goal is to create a multi petaflop systems.
