Exploring Efficiencies in Data Reduction, Analysis, and Distribution in the Exascale Era
No full text
DataDirect Networks (DDN) is world leader in massively scalable storage. Fellinger will discuss how the growth of data sets beyond the petabyte boundary presents new challenges to researchers in delivering and extracting usable information. He will also explore a Big Data processing architecture that overcomes constraints in network bandwidth and service layers in large-scale data distribution to enable researchers to request raw data through a filter or an analysis library. This technology, operating directly within the storage device, enables the reduction of service latency and process cycles to provide a more efficient feedback loop in iterative scientific experiments to increase data-intensive processing efficiency by up to 400%.

Optimized Architectural Approaches in Hardware and Software Enabling Very High Performance Shared Storage Systems
No full textThere are issues encountered in high performance storage systems that normally lead to compromises in architecture. Compute clusters tend to have compute phases followed by an I/O phase that must move data from the entire cluster in one operation. That data may then be shared by a large number of clients creating unpredictable read and write patterns. In some cases the aggregate performance of a server cluster must exceed 100 GB/s to minimize the time required for the I/O cycle thus maximizing compute availability. Accessing the same content from multiple points in a shared file system leads to the classical problems of data "hot spots" on the disk drive side and access collisions on the data connectivity side. The traditional method for increasing apparent bandwidth usually includes data replication which is costly in both storage and management. Scaling a model that includes replicated data presents additional management challenges as capacity and bandwidth expand asymmetrically while the system is scaled. In some cases, systems must also be designed for minimum acceptable bandwidths in the case of a subsystem failure such as a disk drive or data channel leading to increased hardware and management costs. An architectural model will be presented that is in use today in demanding high performance shared access environments. This architecture allows simultaneous data access requiring high bandwidths without the use of data replication. Data can be shared in dynamic multiple path environments allowing for multiple point simultaneous data analysis without a concern for data "hot spots". Further benefits include online scalability where bandwidth and capacity scale linearly as the system is expanded. Additionally, planning for subsystem failures is greatly simplified since the system throughput is maintained regardless ofsystem status. An object based file system will also be presented that is highly scalable and can take full advantage of the hardware architecture. The future roadmap of both the hardware and software will be discussed including block level interfaces that will improve data movement efficiency through the server layer.

From Pedrolino to a Pierrot: The Origin, Ancestry and Ambivalence of the British Pierrot Troupe
No full textIn this article, the author considers the British development of the seaside Pierrot troupe, arguing that its construction is consistent with the notion of invented tradition, and the associated concerns with identity and nationality. Tracing the history of the character from its origins as Pedrolino in the commedia dell’arte, the article considers the traditional and novel elements of the British form. This also allows a brief account of the origin and aesthetics of the British tradition. Reflecting on the synthesis of the archaic and contemporary dimensions of the form, the author proposes that the new structure constructed an ambivalent class of character. The composition of both troupes and audiences was drawn from across the range of social strata. Through its collectivity and its treatment of contemporary social themes, it is argued the British Pierrot troupe approached and negotiated questions of a cultural and national identity in the late-Victorian period.

The collapsible space between us : the interrelationship between testifier, author, and reader in Dave Eggers's "What Is the What"
No full textThesis (M.A.)--Georgetown University, 2009.; Includes bibliographical
references. This project investigates the collaborative relationship between testifier
(Valentino Achak Deng, a Lost Boy of Sudan), author (Dave Eggers), and readers in Dave Egger's
What Is the What. I explore the changing genre of memoirs. I use narrative and reader-response
theories to analyze Eggers's meticulous narrative construction. Finally, I argue that Eggers
builds a collaborative relationship with the reader in order to transform them into an
