Scheduling resources in multi-user, heterogeneous, computing environments with SmartNet

Abstract: It is increasingly common for computer users to have access to several computers on a network, and hence to be able to execute many of their tasks on any of several computers. The choice of which computers execute which tasks is commonly determined by users based on a knowledge of computer speeds for each task and the current load on each computer. A number of task scheduling systems have been developed that balance the load of the computers on the network, but such systems tend to minimize the idle time of the computers rather than minimize the idle time of the users. The paper focuses on the benefits that can be achieved when the scheduling system considers both the computer availabilities and the performance of each task on each computer. The SmartNet resource scheduling system is described and compared to two different resource allocation strategies: load balancing and user directed assignment. Results are presented where the operation of hundreds of different networks of computers running thousands of different mixes of tasks are simulated in a batch environment. These results indicate that, for the computer environments simulated, SmartNet outperforms both load balancing and user directed assignments, based on the maximum time users must wait for their tasks to finish.

The gSOAP Toolkit for Web Services and Peer-to-Peer Computing Networks

Abstract: This paper presents the gSOAP stub and skeleton compiler. The compiler provides a unique SOAP-to-C/C++ language binding for deploying C/C++ applications in SOAP Web Services, clients, and peer-to-peer computing networks. gSOAP enables the integratation of (legacy) C/C++/Fortran codes, embedded systems, and real-time software in Web Services, clients, and peers that share computational resources and information with other SOAP-enabled applications, possibly across different platforms, language environments, and disparate organizations located behind firewalls. Results on interoperability, legacy code integration, scalability, and performance are given.

Computer apparatus and method for providing a common user interface for software applications accessed via the world-wide web

Abstract: The present invention provides the capability to easily access many different application programs over the WWW via a common user interface. By providing standard procedures, routines, tools, and software "hooks" for accessing software applications over the WWW, software developers can concentrate on the functionality of the application program and easily use HTML to provide a GUI interface for the application program. HTML is a well-known language which can be used by almost any computer system on the market today. In addition, since HTML is a fairly well controlled and standardized language, new software application features can be added as they are developed and supported by HTML. In addition, since HTML is a widely adopted, non-proprietary technology, the present invention can provide open access to a large market for even very small software developers. Further, the present invention also allows software developers to adopt a standard access protocol, which allows them to provide support for any computer system which is capable of utilizing a HTML cognizant browser. Finally, by providing easy-to-implement, standardized solutions to the issues of user interface, authentication/security, and web transaction support, the common user interface of the present invention overcomes the limitations existing in previous solutions.

An overview of the Real-Time CORBA specification

Abstract: A growing class of real-time systems require end-to-end support for various quality-of-service (QoS) aspects, including bandwidth, latency, jitter and dependability. Applications include command and control, manufacturing process control, videoconferencing, large-scale distributed interactive simulation, and testbeam data acquisition. These systems require support for stringent QoS requirements. To meet this challenge, developers are turning to distributed object computing middleware, such as the Common Object Request Broker Architecture, an Object Management Group (OMG) industry standard. In complex real-time systems, DOC middleware resides between applications and the underlying operating systems, protocol stacks and hardware. CORBA helps decrease the cycle time and effort required to develop high-quality systems by composing applications using reusable software component services rather than building them entirely from scratch. The Real-Time CORBA specification includes features to manage CPU, network and memory resources. The authors describe the key Real-Time CORBA features that they feel are the most relevant to researchers and developers of distributed real-time and embedded systems.
