Abstract
[ES] La computación en la nube (cloud computing) ofrece servicios de computación bajo demanda a través de una red (habitualmente internet). Es un servicio ampliamente utilizado en la actualidad y, por tanto, existe una gran cantidad de trabajo centrado en el análisis y la mejora de prestaciones de este tipo de servicios. El presente proyecto se centra en cargas de latencia crítica, que son aquellas que deben garantizar una latencia máxima dentro de un umbral para evitar que los usuarios sufran una degradación de prestaciones, cuantificada en términos de calidad de servicio. Aplicaciones como los servicios de búsqueda, el reconocimiento de texto o imágenes y la consulta de bases de datos son aplicaciones de latencia crítica típicas. El presente proyecto propone analizar las prestaciones de este tipo de cargas cuando se ejecutan en un procesador con soporte para la ejecución simultanea de hilos (SMT) utilizando la herramienta perf para determinar las estructuras del procesador que principalmente limitan sus prestaciones.
[EN] Cloud computing offers computing services on demand over a network (usually the internet). It is a widely used service today and, therefore, there is a large amount of work focused on the analysis and improvement of the benefits of this type of service. This project focuses on critical latency loads, which are those that must guarantee maximum latency within a threshold to prevent users from suffering a performance degradation, quantified in terms of quality of service. Applications such as search services, text or image recognition, and database queries are typical latency-critical applications. This project proposes to analyze the performance of this type of workloads when running on a simultaneous multithreading (SMT) processor using the perf tool to determine the processor structures that mainly limit their performance.
