Modern user-facing applications deployed in datacenters use a distributed system architecture that exacerbates the latency requirements of their constituent microservices (30-250$\mu$s). Existing CPU power-saving techniques degrade the performance of these applications due to the long transition latency (order of 100$\mu$s) to wake up from a deep CPU idle state (C-state). For this reason, server v...Show More
User-facing applications running in modern datacenters exhibit irregular request patterns and are implemented using a multitude of services with tight latency requirements (30–250$\mu$s). These characteristics render existing energy-conserving techniques ineffective when processors are idle due to the long transition time (order of 100$\mu$s) from a deep CPU core idle power state (C-state). While ...Show More
