The energy efficiency of program executions is an active research field in recent years and the influence different programming styles on consumption part effort.In this article, we concentrate SIMD study effect vectorization performance as well power consumption.Especially, programs using AVX instructions are considered focus load store instruction set.Several semantically similar but selected used to build versions for same algorithm.As example application, Gaussian elimination has been chosen due its interesting feature arrays varying length each factorization step.Five have implemented, which uses instructions.Performance, power, measurements all provided Intel Sandy Bridge, Haswell Skylake architectures results discussed analyzed.
