Programming scientific and distributed workflow with Triana services

TLDR

Triana supports multiple distribution mechanisms and underlying architectures. The paper presents a real‑world application scenario using three workflow types in Triana: serial scientific, job submission, and monitoring workflows. The authors employ the Grid Application Prototype (GAP), a middleware‑independent abstraction layer, to advertise, discover, and communicate with Web and P2P services. Gravitational‑wave search algorithms were distributed across the European GridLab testbed via Web services, Globus, and P2P infrastructures, demonstrating effective computation and data distribution. © 2005 John Wiley & Sons, Ltd.

Abstract

Abstract In this paper, we discuss a real‐world application scenario that uses three distinct types of workflow within the Triana problem‐solving environment: serial scientific workflow for the data processing of gravitational wave signals; job submission workflows that execute Triana services on a testbed; and monitoring workflows that examine and modify the behaviour of the executing application. We briefly describe the Triana distribution mechanisms and the underlying architectures that we can support. Our middleware independent abstraction layer, called the Grid Application Prototype (GAP), enables us to advertise, discover and communicate with Web and peer‐to‐peer (P2P) services. We show how gravitational wave search algorithms have been implemented to distribute both the search computation and data across the European GridLab testbed, using a combination of Web services, Globus interaction and P2P infrastructures.
