“…The system uses queues for different request types (deterministic, statistical, and best-effort). In [20], a decentralized service discovery system is discussed for global computing grids. This system seeks higher scalability and improved fault-tolerance by using a hierarchy of brokers with node replication.…”

DIET (Distributed Interactive Engineering Toolbox) is a toolbox for the construction of Network Enabled Server systems. Client requests for computational services are automatically matched with available resources by a distributed hierarchy of scheduling agents. Traditionally NES systems have used a centralized agent for performance prediction and resource information management; in DIET, these services are distributed by providing them at the DIET server level. DIET has traditionally offered an online scheduling model whereby all requests are scheduled immediately or refused. This approach can overload interactive servers in high-load conditions and does not allow adaptation of the schedule to task or data dependencies. In this article we consider an alternative model based on active management of the flow of requests throughout the system. We have added support for (1) limiting the number of concurrent requests on interactive servers, (2) server and agent-level queues, and (3) window-based scheduling algorithms whereby the request release rate to servers can be controlled and some re-arrangement of request to host mappings is possible. We present experiments demonstrating that these approaches can improve performance and that the overheads introduced are not significantly different from those of the standard DIET approach. Key

“…These works pay attention to a decentralized architecture instead of a centralized one. In such network, the central database or server has been removed and hierarchical [6] resource discovery architectures. A hierarchical architecture is quite complicated, whereas a flat architecture is easier to implement, and there is no doubt to its scalability.…”

Resource discovery in a Grid environment is a critical problem, as a typical Grid system includes a very large number of resources which must be readily identified and accessed to run applications. This paper presents a time-to-live based multi-resources reservation algorithm on resource discovery in Grid environment, which enables the sharing, selection, and aggregation of a wide variety of geographically distributed computational resources, Our algorithm be easily implemented. The deadline for resource discovery time is decided with time-to-live value. With our algorithm, the more resources are automatically decided for any request if multiple available resources are found on forward path of resource discovery, select the best resource from a the table of available matching resources.

“…Here, registries were replicated for fault-tolerance purposes. In [163], a faulttolerant service discovery system was described that is built on top of the Jini Service Discovery protocol [164]. This approach exploited the inherent redundancy of Jini lookup services to build a distributed, hierarchical index of grid resources in which index nodes are replicated and geographically distributed.…”

cdabrowski@nist.gov SUMMARYIn recent years, grid technology has emerged as an important tool for solving computeintensive problems within the scientific community and in industry. To further the development and adoption of this technology, researchers and practitioners from different disciplines have collaborated to produce standard specifications for implementing largescale, interoperable grid systems. The focus of this activity has been the Open Grid Forum, but other standards development organizations have also produced specifications that are used in grid systems. To date, these specifications have provided the basis for a growing number of operational grid systems used in scientific and industrial applications. However, if the growth of grid technology is to continue, it will be important that grid systems also provide high reliability. In particular, it will be critical to ensure that grid systems are reliable as they continue to grow in scale, exhibit greater dynamism, and become more heterogeneous in composition. Ensuring grid system reliability in turn requires that the specifications used to build these systems fully support reliable grid services. This study surveys work on grid reliability that has been done in recent years and reviews progress made toward achieving these goals. The survey identifies important issues and problems that researchers are working to overcome in order to develop reliability methods for large-scale, heterogeneous, dynamic environments. The survey also illuminates reliability issues relating to standard specifications used in grid systems, identifying existing specifications that may need to be evolved and areas where new specifications are needed to better support reliability.
