The conventional wisdom is that CPU resources such as cores, caches, and memory
bandwidth must be partitioned to achieve performance isolation between tasks. Both the …

Interactive services, such as Web search, recommendations, games, and finance, must
respond quickly to satisfy customers. Achieving this goal requires optimizing tail (eg, 99th+ …

Interactive service providers have strict requirements on high-percentile (tail) latency to meet
user expectations. If providers meet tail latency targets with less energy, they increase …

Multi-tenancy for latency-critical applications leads to resource interference and
unpredictable performance. Core reconfiguration opens up more opportunities for …

A commercial web search engine shards its index among many servers, and therefore the
response time of a search query is dominated by the slowest server that processes the …

Interactive web services increasingly drive critical business workloads such as search,
advertising, games, shopping, and finance. Whereas optimizing parallel programs and …

Web services from search to games to stock trading impose strict Service Level Objectives
(SLOs) on tail latency. Meeting these objectives is challenging because the computational …

Managing tail latency is a primary challenge in designing large-scale Internet services.
Queuing is a major contributor to end-to-end tail latency, wherein nominal tasks are …

Infrastructure as a Service (IaaS) Clouds have grown increasingly important. Recent
architecture designs support IaaS providers through fine-grain configurability, allowing …

Most multi-core architectures nowadays support dynamic voltage and frequency scaling
(DVFS) to adapt their speed to the system's load and save energy. Some recent …
