LISA (Localhost Information Service Agent)
Grid computing has gained an increasing importance in the last years,
especially in the academic environments, offering the possibility to rapidly
solve complex scientific problems. The monitoring of the Grid jobs has a vital
importance for analyzing the system's performance, for providing the users an
appropriate feed-back, and for obtaining historical data which may be used for
performance prediction. Several monitoring systems have been developed, with
different strategies to collect and store the information. We shall present
here a solution based on MonALISA, a distributed service for monitoring,
control and global optimization of complex systems, and LISA, a component
application of MonALISA which can help in optimizing other applications by
means of monitoring services. The advantages of this system are, among others,
flexibility, dynamic configuration, high communication performance.Comment: Proc. of the 15th International Conference on Control Systems and

A Distributed Agent Based System to Control and Coordinate Large Scale Data Transfers
We present a distributed agent based system used to monitor, configure and
control complex, large scale data transfers in the Wide Area Network. The
Localhost Information Service Agent (LISA) is a lightweight dynamic service
that provides complete system and applications monitoring, is capable to
dynamically configure system parameters and can help in optimizing distributed
applications.
As part of the MonALISA (Monitoring Agents in A Large Integrated Services
Architecture) system, LISA is an end host agent capable to collect any type of
monitoring information, to distribute them, and to take actions based on local
or global decision units. The system has been used for the Bandwidth Challenge
at Supercomputing 2006 to coordinate global large scale data transfers using
Fast Data Transfer (FDT) application between hundreds of servers distributed on
major Grid sites involved in processing High Energy Physics data for the future
Large Hadron Collider experiments.Comment: Proc. of 16th International Conference on Control Systems and

Simulation Framework for Modeling Large-Scale Distributed Systems
Simulation has become the evaluation method of choice for many areas of
distributing computing research. However, most existing simulation packages
have several limitations on the size and complexity of the system being
modeled. Fine grained simulation of complex systems such as Grids requires high
computational effort which can only be obtained by using an underlying
distributed architecture. We are proposing a new distributed simulation system
that has the advantage of being able to model very complex distributed systems
while hiding the computational effort from the end-user.Comment: International Conference on Control Systems and Computer Science
