Program comprehension is the most expensive activity of software maintenance. The diierent phases of a reuse reengineering process involves comprehension activities for understanding the structure of existing systems, the functionality implemented by a reuse-candidate module and the reengineering eeort. We present an integrated environment implemented in Prolog for reuse reengineering existing ...

In this paper we present our most recent work carried out in the wider context of the IST-ADRENALIN project, to facilitate formation and lifecycle management of networked enterprises. The projects focus is in designing and building an execution “kernel” for mobile agent applications written in Java, using the Aglets platform and integrating it with any existing ERP system. For integrating mobil...

A knowledge management system is more than an archive of textual documents; it provides context information, allowing to know which documents where used by people with a common goal. In the hypothesis that a set of textual documents with a common context can be assimilated to the long term memory of a human expert executor, we can use on them mining techniques inspired by the mechanic of human ...

Nested parallelism exists in scientific codes that are searching multi-dimensional spaces. However, implementations of nested parallelism often have overhead and load balance issues. The Orbital Analysis code we present exhibits a sparse search space, significant load imbalances, and stopping when the first solution is reached. All these aspects of the algorithm exacerbate the problem of using ...

The production process uses various management and control methods, which are the driving force for development improvement of production, its efficiency. most important elements object, method executor control, as well regulatory documentation control. Improving competitiveness demand consumers is provided through a multi-level system that allows to monitor compliance products with technologic...

In this paper, we study one kind of irregular computation on distributed arrays, the irregular prefix operation, that is currently not well taken into account by the standard data-parallel language HPF2. We show a parallel implementation that efficiently takes advantage of the independent computations arising in this irregular operation. Our approach is based on the use of a directive which cha...

Sheer increase in volume of data over the last decade has triggered research in cluster computing frameworks that enable web enterprises to extract big insights from big data. While Apache Spark is gaining popularity for exhibiting superior scale-out performance on the commodity machines, the impact of data volume on the performance of Spark based data analytics in scale-up configuration is not...

The engineers who analyze traac on high band-width networks must lter and aggregate either recorded traces of network packets or live traac from the network itself. These engineers perform operations similar to database queries, but cannot use conventional data managers because of performance concerns and a semantic mismatch between the analysis operations and the operations supported by commer...

In this paper, we present our contribution for handling irregular applications with HPF2 and some experimental results. We propose a programming style of irregular applications close to the regular case, so that both compile-time and run-time techniques can be more easily performed. We use the well-known tree data structure to represent irregular data structures with hierarchical access, such a...

Object-relational databases management systems (ORDBMS) extend the capabilities of the relational databases by allowing definition of new data types and methods to operate on these data types while retaining most of the relational model semantics. In this paper, we examine issues related to parallel processing of queries in object-relational model with respect to efficient storage and retrieval...
