Title
Analytical Energy Models for MPI Communications on a Sandy-Bridge Architecture
Abstract
Complexity in parallel computation for current HPC systems has being modeled in order to estimate time and energy consumption, which have been conduced to evaluate real costs. Communication analytical models for time and energy comsumption are an attractive issue as part of this cost analysis in parallel computation. In this paper, we present time and energy analytical models for MPI communications using OSU micro benchmarks under Sandy Bridge-EP computer architecture. RAPL (Running Average Power Limit) interface has been setup to provide mechanisms to enforce real energy consumption measurements for OSU micro benchmarks on this architecture. Our applied methodology defines an experimental framework based on several core configurations and different transmission rates. The RAPL interface allows us to obtain different energy values for the OSU benchmark executions. The measures obtained are used to obtain time and energy consumption parameters of our models, establishing average errors below 1% for almost all configurations in real executions under this computer architecture for an ad-hoc model. Alternative and simpler time and energy models are also proposed with errors up to 3.1% for the worst case.
