Corporations are using computational GRIDs to improve their operations. Future GRIDs will allow an organisation to take advantage of computational GRIDs without having to develop a custom in-house solution. GRID Resource Providers (GRP) make resources available on the GRID so that others may use these resources. GRPs allow companies to make use of a range of resources such as processing power or mass storage. However simply providing resources is not enough to ensure the success of a computational GRID. Access to these resources must be controlled otherwise computational GRIDs will simply evolve to become a victim of their own success, unable to offer a suitable Quality of Service (QoS) to any user. The task of providing a standard querying mechanism for Computational GRID Environments (CGE) has already witnessed considerable work from groups such as the Globus project who have delivered the Metacomputing Directory Service (MDS) which provides a means to query devices attached to the GRID. This paper describes a monitoring component both capable of the dynamic discovery of available resources in a computing GRID environment and executing user jobs on the available resource at a given moment in time. Consideration has been paid to integrating with GRID accounting systems.

“…Security has long been a gleam in the eye of the QoS community: many QoS research and development "request for proposals" and QoS system-design presentation slides have included a placeholder for security, without defining security as a true QoS dimension (as above). Some of these presentations have provided access control mechanisms within the QoS framework (Sabata, Chatterjee, Davis, Sydir, Lawrence, 1997) (Lee, et al, 1998), but they have only touched on security as a QoS dimension.…”

“…Other systems such as Infospheres [CRSM96] and Globe [STKS98] use a distributed object model to construct large scale distributed systems. Globus, a metacomputing framework defines a QoS component called Qualis [LKSR98] where low level QoS mechanisms can be integrated and tested. The QuO project from BBN [ZBS97] deals with the specification, monitoring and control of application level QoS.…”

With the evolution of the global information infrastructure, service providers will need to provide effective and adaptive resource management mechanisms that can serve more concurrent clients and deal with applications that exhibit Quality of Service (QoS) requirements. Flexible, scalable and customizable middleware can be used as enabling technology for next generation systems that adhere to the QoS requirements of applications that execute in highly dynamic distributed environments. To enable application aware resource management, we are developing a customizable and composable middleware framework called CompOSE|Q based on a reflective metamodel. In this paper, we describe the architecture and runtime environment for CompOSE|Q and briefly assess the performance overhead of the additional flexibility. We also illustrate how flexible communication mechanisms can be supported efficiently in the CompOSE|Q framework.
