Abstract

This paper presents the design and the automation of a methodology (SciDC) for the creation, execution and administration of large computational and parametric experiments in distributed systems. This methodology is oriented to be a part of a workflow specification framework. These computational experiments involve the execution of a large number of tasks, the grouping of the results and their interpretation. This computational problem is automatically broken down and distributed in a transparent way between local or remote computational resources in a distributed environment. A procedure for specifying experiments is provided, which can work as a part of a general workflow specification procedure. It takes into account the conditions for executing the model, the strategy for executing simultaneously the processes of the computational experiment and provisions for deferred presentation of the results.
