In this work, we optimise the Android IO stack for user-level filesystem. Android imposes user-level filesystem over native filesystem partition to provide flexibility in managing the internal storage space and to maintain host compatibility. The overhead of user-level filesystem is prohibitively large and the native storage bandwidth is significantly under-utilised. We overhauled the FUSE laye...

We study the problem of using proxy servers to stream video stored at a geographically separate location. The separation of the server and the storage introduces a nonnegligible delay in retrieving video frames in real time. To ensure network stability, we use an additive-increase and multiplicative-decrease transport protocol to support the streaming process. We develop an effective scheme to ...

A novel single-chip shared buffer ATM switch architecture is presented, in which a Content Addressable Memory (CAM) is used to control access to the shared buffer RAM, in place of a linked list mechanism. Switch operation is explained in detail, and performance is compared to that of a Linked List switch. Memory capacity requirements are decreased, and cell storage and retrieval is simplified. ...

Scientific discoveries are increasingly dependent upon the analysis of large volumes of data from observations and simulations of complex phenomena. Scientists compose the complex analyses as workflows and execute them on largescale HPC systems. The workflow structures are in contrast with monolithic single simulations that have often been the primary use case on HPC systems. Simultaneously, ne...

Three variants of the chloramine-T radioiodination method were used to iodinate staphylococcal enterotoxin A with 125I. Only one method consistently produced usable labels for radioimmunoassay. The iodine incorporation was 55 to 76%; the specific activity was 3.5 to 5.5 muCi/microgram of enterotoxin, and the label was extremely stable on storage at -20 degrees C. Determinations of the enterotox...

BACKGROUND In modern biotechnology, there is a need for pausing cell lines by cold storage to adapt large-scale cell cultures to the variable demand for their products. We compared various cell culture media/solutions for cold storage of Vero-B4 kidney cells, a cell line widely used in biotechnology. RESULTS Cold storage in RPMI 1640 medium, a recommended cell culture medium for Vero-B4 cells...

With the increasing processing speeds, there is a shift away from the paradigm of centralized, sequential storage systems towards distributed and network based storage systems. Further, with the new imaging and real time multimedia applications, it is becoming more than ever important to design powerful, efficient and scaleable U 0 systems. In this paper, the requirements of storage subsystems ...

This paper presents a new approach to global clock distribution in which traditional tree-driven grids are augmented with onchip inductors to resonate the clock capacitance at the fundamental frequency of the clock node. Rather than being dissipated as heat, the energy of the fundamental resonates between electric and magnetic forms. The clock drivers must only provide the energy necessary to o...

Multimedia computing requires support for heterogeneous data types with differing storage, communication and delivery requirements. Continuous media data types such as audio and video impose delivery requirements that are not satisfied by conventional physical storage organizations. In this paper we describe a physical organization for multimedia data based on the need to support the delivery o...
