In enterprise data centers power usage is a problem impacting server density and the total
cost of ownership. Storage uses a significant fraction of the power budget and there are no …

Benchmarking is critical when evaluating performance, but is especially difficult for file and
storage systems. Complex interactions between I/O devices, caches, kernel daemons, and …

Local storage is required in many sensor network applications, both for archival of detailed
event information, as well as to overcome sensor platform memory constraints. Recent gains …

Reducing power consumption for server-class computers is important, since increased
energy usage causes more heat dissipation, greater cooling requirements, reduced …

Logging has been a common practice for monitoring and diagnosing performance issues.
However, logging comes at a cost, especially for large-scale online service systems. First …

WheelFS is a wide-area distributed storage system intended to help multi-site applications
share data and gain fault tolerance. WheelFS takes the form of a distributed file system with …

We present a new verifiable secret redistribution protocol for threshold sharing schemes that
forms a key component of a proposed archival storage system. Our protocol supports …

Speculator provides Linux kernel support for speculative execution. It allows multiple
processes to share speculative state by tracking causal dependencies propagated through …

Mobile devices face a diverse and dynamic set of networking options. Using those options to
the fullest requires knowledge of application intent. This paper describes Intentional …

Increasingly people manage and share information across a wide variety of computing
devices from cell phones to Internet services. Selective replication of content is essential …
