N2 - Models extending Amdahl’s law have been developed to study the behavior of parallel programs energy consumption. In addition, it has been shown that energy consumption of those programs also relies on the layout of the resources on the chip, such as power supply. Other extensions over Amdahl’s law have been conducted to study the behavior of parallel programs speedup for frequency variable processors. Previous models have focused on the use of Turbo Boost in the parallel regions of a program, without considering that Turbo Boost also affects the sequential regions. Hence, we present a model to analyze energy consumption of parallel programs executed on Intel multicore processors with Turbo Boost frequencies to cover this gap. The model is an extension to Amdahl’s law, and it is validated with a double-precision matrix multiplication running on Intel multicore processors that enable Turbo Boost technology.
