Fujitsu develops technology to visualize the energy required to execute software
Fujitsu Laboratories today announced that it has developed technology that precisely calculates the energy required to execute various software programs running on server CPUs, for energy-efficient programming. Servers equipped with Intel-made CPUs include a power-control mechanism that can measure power consumption for the CPU as a whole. Until now, however, it was not possible to calculate the energy required to execute software on a core-by-core basis, so it has been difficult to take a software-based approach to reducing power consumption. Now Fujitsu Laboratories has developed technology that uses information that can be tracked at the individual core level, such as clock cycles and cache-hit percentages, to estimate energy consumption in detail, down to the program module level. This makes energy-efficient programming a more efficient process, contributing to both lower overall server energy usage and, by using surplus power, higher software performance. Details of this technology are being presented at the...
