A Rate-based Prefiltering Approach to BLAST Acceleration

Dionysios Pnevmatikatos, Sotiria Fytraki

DNA sequence comparison and database search have evolved in the last years as a field of strong competition between several reconfigurable hardware computing groups. In this paper we present a BLAST preprocessor that efficiently marks the parts of the data ...

On the prediction of heat transfer in micro-scale flow boiling

John Richard Thome, Wei Zhang, Lorenzo Consolini

Xu et al. have recently published a set of results for boiling heat transfer measurements in a multi- channel micro- scale evaporator for flow boiling of acetone in triangular cross- section channels ( hydraulic diameter of 155.4 mm). In the present collab ...

Database Replication Using Generalized Snapshot Isolation

Willy Zwaenepoel, Sameh Mohamed Elnikety, Fernando Pedone

Generalized snapshot isolation extends snapshot isolation as used in Oracle and other databases in a manner suitable for replicated databases. While (conventional) snapshot isolation requires that transactions observe the “latest” snapshot of the database, ...

NEOBASE: databasing the neocortical microcircuit

Henry Markram

Mammals adapt to a rapidly changing world because of the sophisticated perceptual and cognitive function enabled by the neocortex. The neocortex, which has expanded to constitute nearly 80% of the human brain seems to have arisen from repeated duplication ...

C-JDBC: Flexible Database Clustering Middleware

Willy Zwaenepoel, Emmanuel Cecchet

Large web or e-commerce sites are frequently hosted on clusters. Successful open-source tools exist for clustering the front tiers of such sites (web servers and application servers). No comparable success has been achieved for scaling the backend database ...

Audio-Video Person Clustering in Video Databases

Jean-Marc Odobez

A methodology towards person clustering in meeting databases is presented in this report. Such goal is generic to a number of problem in computer vision and more specifically in content-based video indexing and retrieval. First, the audio-stream was consid ...

Conflict-Aware Scheduling for Dynamic Content Applications

Willy Zwaenepoel

We present a new lazy replication technique, suitable for scaling the back-end database of a dynamic content site using a cluster of commodity computers. Our technique, called conflict-aware scheduling, provides both throughput scaling and 1-copy serializa ...

Database Integration: the Key to Data Interoperability

Stefano Spaccapietra, Christine Parent

Most of new databases are no more built from scratch, but re-use existing data from several autonomous data stores. To facilitate application development, the data to be re-used should preferably be redefined as a virtual database, providing for the logica ...
