Infection with respiratory syncytial virus (RSV) in children can progress to respiratory distress and acute lung injury necessitating mechanical ventilation (MV). MV enhances apoptosis and inflammation in mice infected with pneumonia virus of mice (PVM), a mouse pneumovirus that has been used as a model for severe RSV infection in mice. We hypothesized that the Fas/Fas ligand (FasL) system, a d...

In this paper, the benefits of parallel computing using a workstation cluster are explored for satellite orbit prediction. Data and function decomposition techniques are used. Speedup and throughput are the performance metric studied. The software employed for parallelization was the Parallel Virtual Machine (PVM) developed by the Oak Ridge National Laboratory. PVM enables a network of heteroge...

As workstation clusters gain popularity as a parallel computing platform,there is an increasing need for performance tools that support these platforms. Performance prediction is important for performance analysis of scalable parallel applications. Although there are several performance tools available that work with PVM programs,none are capable of performance prediction. We have developed the...

In this paper the simulation and assessment tool CLUE is described. This tool is able to simulate the performance of parallel programs using the message passing library PVM for communication, run on arbitrary parallel m achines, including PC clusters. CLUE redirects calls to PVM to its own functions, providing an additional layer between an application and PVM. The simulation is driven by the a...

In this paper a methodology for parallelizing neural network training algorithms is described, based on the parallel evaluation of the error function and gradient using the Parallel Virtual Machine (PVM). PVM is an integrated set of software tools and libraries that emulates a general–purpose, flexible, heterogeneous concurrent computing framework on interconnected computers of varied architect...

A Migratable User-Level Process Package for PVM Ravindranath Bala Konuru Oregon Graduate Institute of Science & Technology Supervising Professors: Steve Otto and Jonathan Walpole This dissertation studies an approach to supporting e cient processor virtualization and dynamic load balancing for message-based, parallel programs. We propose the User-Level Process (ULP) abstraction that can be used...

Message passing libraries such as Parallel Virtual Machine (PVM) and Message Passing Interface (MPI) provide a common Application Programming Interface (API) to implement parallel programs across multiple computers. Such libraries provide a means to program a collection of normally independent computers to work cooperatively on a single computation. However, for programs written in C and Fortra...
