A Peer-to-Peer Approach to Resource Discovery in Grid Environments

Abstract: Computational grids provide mechanisms for sharing and accessing large and heterogeneous collections of remote resources such as computers, online instruments, storage space, data, and applications. Resources are requested (”discovered”) by specifying a set of desired attributes. Resource attributes have various degrees of dynamism, from mostly static attributes, such as operating system version, to highly dynamic ones, such as available network bandwidth or CPU load. Another dimension of dynamism is introduced by variable and highly diverse sharing policies: resources are made available to the grid community based on locally defined and potentially changing policies. In such a dynamic environment it is often more efficient to forward requests than to disseminate resource information that soon becomes stale. We investigate a set of request forwarding strategies in a peer-to-peer like architecture: each peer acts independently, based on possibly partial or outdated information about the rest of the system and forwards the requests it cannot solve to another peer. We investigate these strategies in environments with different sharing characteristics, different request distributions, and on networks of up to 32768 (215) peers. The results allow to characterize the correlation between resource discovery performance based on request forwarding, resource sharing characteristics, and user request patterns.

Method and system of remote diagnostic, control and information collection using a shared resource

Abstract: A system, method and program product for diagnosing, controlling and collecting information from devices. Information regarding events of a target application executing in an application unit is collected and formatted into one of multiple data formats for transmission through one of multiple communication protocols using at least one shared system resource. The formatted data is transmitted through, e.g., e-mail or FTP to a predetermined destination or may be saved to local storage, e.g., a local disk. By sharing resources, code duplication is reduced or eliminated.

Exploiting locality for data management in systems of limited bandwidth

Abstract: This paper deals with data management in computer systems in which the computing nodes are connected by a relatively sparse network. We consider the problem of placing and accessing a set of shared objects that are read and written from the nodes in the network. These objects are, e.g., global variables in a parallel program, pages or cache lines in a virtual shared memory system, shared files in a distributed file system, or pages in the World Wide Web. A data management strategy consists of a placement strategy that maps the objects (possibly dynamically and with redundancy) to the nodes, and an access strategy that describes how reads and writes are handled by the system (including the routing). We investigate static and dynamic data management strategies.

Electronic document delivery system

Abstract: A document, preferably in a portable format, is forwarded to a remote server ( e.g. using HTTP to push the document to the server). The server sends a generic notification of the document to an intended recipient, and the recipient can download the document from the server using local protocols. A method and system is also provided that sends documents from a desktop computer inside an intranet through a series of firewalls and/or proxy servers to a server residing on the Internet. A computer in an intranet system protected by a firewall or proxy server uses a software application to access the Internet. The software also encodes binary data to be sent as text. This binary data may be subdivided into smaller text packets. The text packets are sent, using HTTP, to a server outside the firewall, which has been configured to accept such text packets. The server converts the text packets back to the original binary data representation. The binary data, once resident on the internet server, can then be forwarded directly to other internet servers, internet desktop computers, printers, or fax machines. A document delivery server is also provided that dynamically customizes the format of a document to be delivered, based on the capabilities of the recipient and the type of document to be delivered. The server attempts to maintain the information contained in the document in a high level representation and deters the decision of when to convert to a lower level representation, thereby maximizing the potential set of options and function at each step in the delivery process.
