In the last years, the availability and models of use of networked computing resources within reach of e-Science are rapidly changing and see the coexistence of many disparate paradigms: high-performance computing, grid, and recently cloud. Unfortunately, none of these paradigms is recognized as the ultimate solution, and a convergence of them all should be pursued. At the same time, recent works have proposed a number of models and tools to address the growing needs and expectations in the field of e-Science. In particular, they have shown the advantages and the feasibility of modeling e-Science environments and infrastructures according to the service-oriented architecture. In this paper, we suggest a model to promote the convergence and the integration of the different computing paradigms and infrastructures for the dynamic on-demand provisioning of resources from multiple providers as a cohesive aggregate, leveraging the service-oriented architecture. In addition, we propose a design aimed at endorsing a flexible, modular, workflow-based computing model for e-Science. The model is supplemented by a working prototype implementation together with a case study in the applicative domain of bioinformatics, which is used to validate the presented approach and to carry out some performance and scalability measurements.

Although conceived for web services, it is shown how BPEL (Business Process Execution Language) can be used to orchestrate a collection of grid services. This is achieved using the technique of CRESS (Communication Representation Employing Systematic Specification) to describe the composition of grid services. CRESS descriptions are automatically translated into LOTOS (Language Of Temporal Ordering Specification), allowing systematic checks for interoperability and logical errors prior to implementation. MUSTARD (Multiple-Use Scenario Test and Refusal Description) is used to validate the generated specification against use case scenarios. The same CRESS descriptions are then automatically converted into BPEL/WSDL code for practical realisation of the composed services. Grid services are executed by Globus Toolkit 4, while their orchestration is supported by the ActiveBPEL engine. The MUSTARD scenarios are used again to evaluate the implementation. The overall approach therefore supports rigorous development and automated creation of orchestrated grid services.

“…This shows that when the number of process instances increases in ActiveBPEL, the number of threads may go well beyond what most systems can handle, eventually making the workflow to be aborted. Also users may run in to deadlocks if they try to limit the size of the thread pool of the servlet container [13]. The above study concludes by deciding that the scalability of ActiveBPEL is limited only by the limited hardware resources, which will be not an acceptable remark for an embeddable engine.…”

“…Interesting study about the scalability of ActiveBPEL engine has been presented in an earlier study [13].According to that ActiveBPEL engine requires two OS threads for the creation of a new BPEL process instance. This shows that when the number of process instances increases in ActiveBPEL, the number of threads may go well beyond what most systems can handle, eventually making the workflow to be aborted.…”

Abstract. Web Services have become the de-facto standard for architecting and implementing business collaborations within and across organization boundaries. Web service composition refers to the creation of new (Web) services by combining the functionalities provided by existing ones. A process-oriented language for service composition has been proposed as WSBPEL. WSBPEL specification defines an XML based formal language and provides a general overview of the framework. However no design and implementation issues are described in it. Most of the available BPEL compliant process engines are heavy weight, complex and not extensible. This paper describes the design and implementation of an embeddable, scalable and extensible WSBPEL compliant process engine. This paper highlights the concepts and strategies that were followed during the design and implementation. Primary contribution of this paper is the design of stateless process model and the design of run time core engine using a multi-processor scheduler.
