System, method, server and device for trial use of application software

Abstract: A system for trial use of application software comprises at least one user device and a server. The server is communicatively coupled to the user device. The server receives a request data for trying an application software, the request data is generated corresponding to an input on the user device, the server executes at least one part of the application software according to the request data and establishes a two-way communication with the user device, and the server and the user device transmits at least one image data and at least one control data via the two-way communication.

Engineering dynamic real-time distributed systems: architecture, system description language, and middleware

Abstract: The paper presents an architectural framework and algorithms for engineering dynamic real-time distributed systems using commercial off-the-shelf technologies. In the proposed architecture, a real-time system application is developed in a general-purpose programming language. Further, the architectural-level description of the system such as composition and interconnections of application software and hardware, and the operational requirements of the system such as timeliness and survivability are specified in a system description language. The specification of the system is automatically translated into an intermediate representation (IR) that models the system in a platform-independent manner. The IR is augmented with dynamic measurements of the system by a language runtime system to produce a dynamic system model. The dynamic model is used by resource management middleware strategies to perform resource management that achieves timeliness and survivability requirements. We present two classes of algorithms: predictive and availability-based, for performing resource allocation. To validate the viability of the approach, we use a real-time benchmark application that functionally approximates dynamic real-time command and control systems. The benchmark results illustrate that the middleware is able to achieve the desired timeliness requirements during a number of load situations. Furthermore, availability-based allocation algorithms perform resource allocation less frequently, whereas predictive algorithms give a better steady state performance for the application.

Method and apparatus to perform an application software migration

Abstract: A method and apparatus to perform a software migration. According to one embodiment of the invention, end-user specific platform information is collected to be used by a set of one or more migration scripts to perform the software migration. The migration scripts are to be executed on an end-user server and generate log files to be used to restart the software migration if an error occurs during the software migration.

Modeling the communication performance of the IBM SP2

Abstract: The objective of this paper is to develop models that characterize the communication performance of a message-passing multicomputer by taking the IBM SP2 as a case study. The paper evaluates and models the three aspects of the communication performance: scheduling overhead, message-passing time, and synchronization overhead. Performance models are developed for the basic communication patterns, enabling the estimation of the communication times of a message-passing application. Such estimates facilitate activities such as application tuning, selection of the best available implementation technique, and performance comparisons among different multicomputers.
