GPUs have evolved to programmable, energy efficient compute accelerators for massively parallel applications. Still, compute power is lost in many applications because of cycles spent on data movement and control instead of computations on actual data. Additional cycles can be lost as well on pipeline stalls due to long latency operations. To improve performance and energy efficiency, the authors introduce GPU-CC: a reconfigurable GPU architecture with communicating cores. It is based on a contemporary GPU, which can still be used as such, but also has the ability to reorganize the cores of a GPU in a reconfigurable network.
