Dok en español #2 ¡Suelten el Krake! Trayendo la Energía al Lazo de Cómputo // Juan A. Fraire

Abstract of the talk…

ENG: Cloud&Heat has always focused on providing energy-efficient data centers. In the last 8 years, we have developed an innovative water cooling technology for servers, converting waste heat into a valuable asset. By doing so, we have already greatly improved the energy efficiency of individual data centers. However, this isn’t enough. To globally maximize the efficiency of distributed data center infrastructures, this talk presents Krake. Krake is an orchestration software for compute-intensive jobs. It improves the global cost and energy efficiency of infrastructures by balancing the load between data centers. Krake evaluates and selects the most efficient site to run jobs based on certain metrics, such as energy availability, heat demand, and latency. It also reacts to changes in the system by migrating jobs. In other words, it ensures a job is run in the most energy- and/or cost-efficient way at any given time.

ESP: Cloud & Heat siempre se ha centrado en proporcionar centros de datos energéticamente eficientes. En los últimos 8 años, hemos desarrollado una innovadora tecnología de refrigeración por agua para servidores, que convierte el calor residual en un activo valioso. Al hacerlo, ya hemos mejorado enormemente la eficiencia energética de los centros de datos individuales. Sin embargo, esto no es suficiente. Para maximizar globalmente la eficiencia de las infraestructuras de centros de datos distribuidos, en esta charla presentaremos Krake. Krake es un software de orquestación para trabajos intensivos en computación. Mejora el costo global y la eficiencia energética de las infraestructuras al equilibrar la carga entre los centros de datos. Krake evalúa y selecciona el sitio más eficiente para ejecutar trabajos según ciertas métricas, como la disponibilidad de energía, la demanda de calor y la latencia. También reacciona a los cambios en el sistema mediante la migración de trabajos. En otras palabras, asegura que un trabajo se ejecute de la manera más eficiente en términos de energía y costo en un momento dado.

Bio…

ES: Juan A. Fraire es investigador asistente en CONICET en Argentina, profesor asociado en la Universidad de Saarland en Alemania y arquitecto de soluciones cloud en Cloud&Heat en Alemania. Su principal interés gira en torno a las aplicaciones en red y distribuidas habilitadas por técnicas informáticas de vanguardia. Además de aplicar esto al dominio del cloud computing en tierra, Juan lidera un esfuerzo internacional para llevar la visión al dominio del espacio. De hecho, Juan es el fundador y presidente del STINT Workshop desde 2014, ha sido coautor de más de 55 artículos publicados en revistas internacionales y conferencias líderes, y ha construído una visión novedosa de redes en su libro “Delay-Tolerant Satellite Network ” en coautoría con colegas de la NASA.

EN: Juan A. Fraire is an assistant researcher at CONICET in Argentina, an associate professor at Saarland University in Germany, and cloud solutions architect at Cloud&Heat in Germany. His main interest revolves around networking and distributed applications enabled by state-of-the-art informatics techniques. Besides applying this to the cloud domain on ground, Juan leads an international effort in pushing the vision into the space domain. Indeed, Juan is the founder and chair of the annual Space-Terrestrial Internetworking Workshop (STINT) since 2014, has co-authored more than 55 papers published in international journals and leading conferences, and has imprinted a novel networking vision in his “Delay-Tolerant Satellite Network” book co-authored with colleagues from NASA.
