The goal of ASKALON is to simplify the development and optimization of applications that can harness the power of Grid computing. The ASKALON project crafts a novel environment based on new innovative tools, services, and methodologies to make Grid application development and optimization for real applications an everyday practice.

Features and Technology

Askalon is designed as a distributed service-oriented architecture comprising the following set of services:
- Resource broker service targets negotiation and reservation of resources required to execute a Grid application.
- Resource monitoring supports the monitoring of Grid resources by integrating and extending existing Grid resource monitoring tools and by developing new techniques for Grid resource monitoring (e.g. rule-based monitoring).
- Information service is a general purpose service for scalable discovery, organisation, and maintenance of resource and application-specific data (including online and post-mortem).
- Workflow executor service targets dynamic deployment, coordinated activation, and fault tolerant completion of activities onto the remote Grid sites.
-
(Meta)-scheduler
performs appropriate mapping of single or multiple workflow
applications onto the Grid. This work continues our initial scheduling
efforts in the context of the ZENTURIO experiment
management and optimization tool.
- Performance prediction is a service through which we are currently investigating new techniques for accurate estimation of execution time of atomic activities and data transfers, as well as of Grid resource availability.
- Performance analysis is a service that unifies the performance monitoring, instrumentation and analysis for Grid applications and supports the performance bottleneck interpretation.
