The relationship between client-server distributed computing and message-passing parallel processing is explored in this work through an experimental RPC framework for the PVM system. The project investigates the potential for RPC to complement asynchronous message passing in PVM { both to expand the domain of applications, and to evaluate the eeectiveness of client-server computing for traditi...
A number of MP interfaces are available today but one of the most popular is the PVM software package. PVM permits the user to conngure his own virtual computer by hooking together a heterogeneous collection of UNIX based machines on which the user has a valid login and which are accessible over some network. To provide high-level graphical support for PVM based program development, an integrat...
ITOUGH2 is an optimization code that allows estimation of any input parameter of the nonisothermal, multiphase flow simulator TOUGH2. ITOUGH2 inversions are computationally intensive because the so-called forward problem, i.e., the simulation of fluid and heat flow through the geologic formation, must be solved many times for different parameter combinations to evaluate the misfit criterion or ...
This paper presents the design and preliminary implementation of MpPVM, a software system that supports process migration for PVM application programs in a non-dedicated heterogeneous computing environment. New concepts of migration point as well as migration point analysis and necessary data analysis are introduced. In MpPVM, process migrations occur only at previously inserted migration point...
Harness is the next generation heterogeneous distributed computing package being developed by the PVM team at Oak Ridge National Laboratory, University of Tennessee, and Emory University. This paper describes the changing trends in cluster computing and how Harness is being designed to address the future needs of PVM and MPI application developers. Harness (which will support both PVM and MPI) ...
Parallel Virtual Machine (PVM) is a widely-used software system that allows a heterogeneous set of parallel and serial UNIX-based computers to be programmed as a single message-passing parallel machine. In this paper, an extension to PVM to support dynamic process migration is presented. Support for migration is important in general-purpose workstation environments since it allows parallel comp...
Background PVM is an established technique for measuring blood [1] and myocardial velocities [2]. However, long scan times can restrict its application. Peak-GRAPPA has been used to accelerate Cartesian PVM up to a factor of 6 (R = 6) without degrading peak velocity measurements [3], however use of efficient k-space trajectories could allow higher temporal resolution (TR) in similar scan time. ...
The PVM system is a programming environment for the development and execution of large concurrent or parallel applications that consist of many interacting, but relatively independent, components. It is intended to operate on a collection of heterogeneous computing elements interconnected by one or more networks. The participating processors may be scalar machines, multiprocessors, or special-p...
Eosinophils are recruited to the airways as a prominent feature of the asthmatic inflammatory response where they are broadly perceived as promoting pathophysiology. Respiratory virus infections exacerbate established asthma; however, the role of eosinophils and the nature of their interactions with respiratory viruses remain uncertain. To explore these questions, we established acute infection...
CAMeL (Computer-Aided Mechatronic Laboratory) is an open CAE design environment for the computer-aided modelling and simulation of complex mechatronic systems. CAMeL consists of a number of tools that, on the basis of the Ada tasking concept, can be combined to form any desired complex system. Communication between the tools is established by passing of messages via channels. This paper will pr...
