Power and Energy Analysis on Intel Single-chip Cloud Computer System

AbstractImproving the computing performance of the multicoreand many-core systems is one of the primary interests tocomputer architecture researchers currently. Message PassingInterface (MPI) and Multi-core techniques are converged to solvethis problem. With performance enhancement, the power andenergy consumption increase correspondingly. The Single-ChipCloud Computer (SCC) is an experimental processor createdby Intel Labs. This paper proposed an approach to study thepower and energy consumption on the 48-core SCC many-coresystem and realized the message passing on the SCC. First, weprofile the execution time, voltage and current on each runningset. Later, we calculated the power and energy consumption, andcompared them with increasing number of cores, varying voltageand frequency levels. Finally, we reached a conclusion focus on itsscalability and relationship between power/energy consumptionand system performance in terms of execution time6 Halama
