Managing Grid Computations: An ORC-Based Approach

Abstract

Abstract.In this paper a model of grid computation that supports both heterogeneity and dynamicity is presented. The model presupposes that user sites contain software components awaiting execution on the grid. User sites and grid sites interact by means of managers which control dynamic behaviour. The orchestration language ORC [9,10] offers an abstract means of specifying operations for resource acquisition and execution monitoring while allowing for the possibility of non-responsive hardware. It is demonstrated that ORC is sufficiently expressive to model typical kinds of grid interactions.

Assessing the Reliability and Cost of Web and Grid Orchestrations

“…The language provides a means for a user to interact with a web or grid environment and to receive responses from it [6]. A brief summary of the language Orc is given here -see [3,7] for a complete description.…”

A Framework for Interactive Parameter Sweep Applications

“…We consider that it is necessary to formally analyze the interaction among this basic grid services within our framework. For analysing the interaction among basic grid services used in the framework, we are considering the use of orchestration language ORC [14]. Grid service interactions including resource discovery, resource contract negotiation, job placement is essential in the development of this interactive framework.…”

“…Grid service interactions including resource discovery, resource contract negotiation, job placement is essential in the development of this interactive framework. It has been shown in [14] that ORC can provide the means to describe these essential features of grid management.…”

Reasoning about orchestrations of web services using partial correctness

“…For example, services are used in the cloud computational model to acquire both software and hardware resources. In [SGC06] it is argued that Orc [Mis04,MC07] provides appropriate combinators for constructing service-based computations. For example, Orc provides operators that can be used to time-out non-responsive services and reschedule computations elsewhere.…”
