Abstract
A día de hoy nuestra sociedad es plenamente consciente de lo que supone el ahorro energético para el medio ambiente. Sabemos que en los centros de procesamiento de datos el consumo energético es realmente elevado y la solución no siempre pasa por obtener una mayor capacidad de computación, sino que en ocasiones puede ser beneficioso sacrificar parte de esta capacidad en favor de una mayor eficiencia energética, con el consecuente ahorro de energía.
El primer paso a dar hasta alcanzar dicha eficiencia, sin embargo, comienza por desarrollar procesos, metodologías y mecanismos que permitan realizar mediciones de consumo fiables, reproducibles y detalladas. Existen en el mercado una amplia variedad de equipos de medición, siendo muy pocos los asequibles económicamente para la gran mayoría de empresas, grupos de investigación o usuarios particulares que requieren de su funcionalidad.
El objetivo principal de nuestro trabajo es proveer de una plataforma precisa, fiable y económica a todos aquellos que quieran ser capaces de medir en tiempo real la potencia eléctrica consumida por un determinado hardware de un equipo, principalmente de altas prestaciones, y poder optimizar de esta manera sus procedimientos de cálculo.
Para conseguir nuestro propósito de accesibilidad, la base principal de desarrollo será una plataforma Open Hardware de bajo coste, que nos permitirá disponer en nuestro entorno de múltiples dispositivos de manera simultánea sin que ello suponga un gran desembolso.
La combinación de un entorno preciso y de bajo coste nos brindará la posibilidad de, por aproximadamente 150€ , instrumentar código de una manera fácil y muy eficaz.
Nowadays, our society is completely conscious of the impact of power saving on the natural environment. As of today, massive datacenters consume a considerable amount of power, and the solution to this problem is not always to attain higher computational throughput, but to trade off part of these computing capabilities for a higher energetic efficiency, with the corresponding energy savings. The first step towards attaining that efficiency is, however, to develop processes, methodologies and mechanisms that provide reliable, reproducible and precise energy consumption measurements. There exist a wide variety of measurement equipment in the market, but only a few are affordable for small companies, research groups, or even individuals requiring their functionality. The main goal of our project is to provide a precise, reliable and affordable platform to the community, with the ability to provide real-time power measurements of a given hardware, mainly focusing on high-performance computing facilities, in order to optimize energy efficiency. To attain our goals in terms of ease of access, the main parts of the project will be based on low-cost Open Hardware, which will allow us to attain a powerful measurement environment at a low acquisition cost. The combination of a precise and low-cost environment will give us the possibility of instrumenting a given code in an easy and effective way for roughly 150€.
