The introduction of personal computing and wireless communication technology provides an option for on site device software updating and data retrieving. This is especially true for any devices sitting in a remote site where computing network is not accessible. In many advanced computing systems, frequent software updating and configuration profiles refreshing are required. This is clumsy and e...

Abstract. Hard disks, most prevalent mass-storage devices, have high power consumption and high response time for random I/O requests. Recent remarkable technology improvement of flash memory has made it a rising secondary storage device but flash memory still has high cost per bit. Usage of heterogeneous storage devices such as a pair of a hard disk and a flash memory can provide reasonable co...

A thermal response model for designing a hybrid thermal energy storage (TES) heat sink is developed. The stabilization time and maximum operating (hot side) temperature-totransition temperature difference are used to characterize the performance of the heat sink. The thermal properties of the PCM employed in the design are investigated. Integration of a design optimization algorithm into a ther...

Storage-class memory (SCM) combines the benefits of a solidstate memory, such as high performance and robustness, with the archival capabilities and low cost of conventional hard-disk magnetic storage. Such a device would require a solid-state nonvolatile memory technology that could be manufactured at an extremely high effective areal density using some combination of sublithographic patternin...

Computer vision applications today run on a wide range of mobile devices. Even though these devices are becoming more ubiquitous and general purpose, we continue to see a whole spectrum of processing and storage capabilities within this class. Moreover, even as the processing and storage capacity of devices are increasing, the complexity of vision solutions and the variety of use cases create g...

First implementations of Quantum-key Distribution Cryptosystems have shown the need to use a storage device on which to keep a copy of the key that such cryptosystems create and distribute between a pair of users. Such users must be able to access their device to take enough key to code and decode the messages they send each other over a public channel. Because of the importance of the key stor...

How do we incorporate security into a high performance commodity storage subsystem? Technology trends and the increasing importance of I/O bound workloads are driving the development of commodity network attached storage devices which deliver both increased functionality and increased performance to end-users. In the network attached world, storage devices co-exist on the network with their cli...

Applications that generate bursty I/O load, like checkpointing, require additional support to perform efficiently on next generation petascale supercomputers. Tens of thousands of processors, generating terabytes of snapshot data at once at each timestep, can easily overwhelm a storage system. Further, even at the current peak I/O bandwidth rates, offered by parallel file system deployments at ...
