We introduce a simple sequential write benchmark and use it to improve the Linux NFS client’s write performance. We reduce the latency of the write() system call, improve SMP write performance, and reduce kernel CPU processing during sequential writes. Memory write throughput to NFS files improves by more than a factor of three.

This paper compares the efficacy of two anomaly detection classifiers with respect to the classification of processes as either intrusive or non-intrusive. To the task of process classification, both classifiers treat processes as system call sequences, encode those system call sequences as text documents, and apply the k-nearest neighbor text categorization method to classify the processes. In...

With the developments of new technologies appearing very quickly, the attention has been focused more on technology than learning. English centers and institutes have mostly been busy accommodating new programs and technologies and hence have not spent enough time to evaluate the CALL programs and technologies employed to find their affordances and limitations. The present study was an attempt ...

1. LET THE GAMES BEGIN: THE OPENING CEREMONIES. For those who think globally, "down under" may provoke thoughts of Australia-the home of the 2000 Olympic Games. For those who think rationally, "down under" may provoke thoughts of denominators of fractions. In this paper, we hope to provoke both. In basic diophantine approximation, the name of the game is to tackle the following: How close do in...

This is an extension of work presented in 12]. It is proved that the seemingly weak architecture Basic Splice introduced there {in which the coordination of processes is done using only a global set with read/write primitives{ can support a distributed implementation of a large class of requirements speciications, namely LPEs (a CRL intermediate representation of speciications).

After decades of schema-centric research on data management and integration, the evolution of data on the web and the adoption of resource-based models seem to have shifted the focus towards an entity-centric approach. Our thesis is that the missing element to achieve the full potential of this approach is the development of what we call an Entity Name System (ENS), namely a system which provid...

Attacks against privileged applications can be detected by analyzing the stream of system calls issued during process execution. In the last few years, several approaches have been proposed to detect anomalous system calls. These approaches are mostly based on modeling acceptable system call sequences. Unfortunately, the techniques proposed so far are either vulnerable to certain evasion attack...
