Sustainable and cost-effective long-term storage remains an unsolved problem. The most widely used storage technologies today are magnetic (hard disk drives and tape). They use media that degrades over time and has a limited lifetime, which leads to ...

Grove is a concurrent separation logic library for verifying distributed systems. Grove is the first to handle time-based leases, including their interaction with reconfiguration, crash recovery, thread-level concurrency, and unreliable networks. This ...

Cloud systems are increasingly being managed by operation programs termed operators, which automate tedious, human-based operations. Operators of modern management platforms like Kubernetes, Twine, and ECS implement declarative interfaces based on the ...

Modern applications are highly concurrent with a diverse mix of activities. One activity can adversely impact the performance of other activities in an application, leading to intra-application interference. Providing fine-grained performance ...

The global scale and challenging requirements of modern cloud applications have led to the development of complex, widely distributed, service-oriented applications. One enabler of such applications is the remote procedure call (RPC), which provides ...

This paper presents DNS-V, a verification framework for our in-production DNS authoritative engine, which is the core of our DNS service. The key idea for automated verification in general is based on the layered verification principle. However, we ...

Silent Data Corruption (SDC) in processors can lead to various application-level issues, such as incorrect calculations and even data loss. Since traditional techniques are not effective in detecting processor SDCs, it is very hard to address problems ...

Datacenter applications expect microsecond-scale service times and tightly bound tail latency, with future workloads expected to be even more demanding. To address this challenge, state-of-the-art runtimes employ theoretically optimal scheduling ...
