Serverless computing has emerged as a widely-used paradigm for running services in the cloud. In serverless, developers organize their applications as a set of functions, which are invoked on-demand in response to events, such as an HTTP request. To

Shared on-chip last-level caches (LLCs) play a key role in capturing the large working sets of today’s data-intensive workloads. However, they pose a fundamental scalability challenge in the transistor-limited post-Moore regime. Recent work has arg
