jGASW: A Service-Oriented Framework Supporting HTC and Non-functional Concerns

Abstract

Although Service-Oriented principles have been widely adopted by High Throughput Computing infrastructure designers, the integration between SOA and HTC is made difficult by legacy. j GASW is a framework for wrapping legacy scientific applications as Web Services and integrating them into an intensive computing-aware SOA framework. It maps complex I/O data structures to command lines and enables dynamic allocation of computing resources; including execution on local hosts or on grid infrastructures; data transfer management and support of non-functional concerns.

Scalable and Resilient Workflow Executions on Production Distributed Computing Infrastructures

“…In our architecture, both middleware and application components are deployed as services. The application code is instrumented non-invasively to comply to this model through a Web service builder aware of DCIs computing capability [19]. Using an SOA approach allows users to scale the execution of their applications and flexibly extend the execution framework according to the computation needs.…”

“…From a user's point of view, an end-toend system enabling the exploitation of DCIs should provide high expressiveness to describe applications; design and enact applications composition making use of consistent interfaces; and transparent access to DCI resources. The framework architecture, based on MOTEUR [20] and jigsaw [19] components, is pictured in Fig. 1.…”

Characterizing Semantic Service Parameters With Role Concepts to Infer Domain-Specific Knowledge at Runtime

“…This deployment shows three collaborating sites A, B, C and end-users interacting with their proper site gateway (Site A) through the client application. Processing tools are syntactically described and instrumented as relocatable bundles through jGASW (Rojas Balderrama et al, 2010) to enable their deployment and invocation on various computing infrastructure. The MOTEUR (Glatard et al, 2008) …”

Service Oriented Configuration Management of ‎Software ‎Architecture

“…Appling these service-oriented principles in this field can create a comprehensive and efficient infrastructure [4] that could be used for composite services and to create any new services required. In this context, service-oriented principles is important to almost all of the principles, models, and standards used in service-oriented architecture that lead to characteristics, such as loose coupling, abstraction, reuse, heritability, autonomy, etc [5]. Applying these principles may improve some issues in configuration management of the infrastructure such as reusability of fine grain at different levels, scalability, flexibility, availability, reliability, complexity, and efficiency.…”
