Automatic model generation is studied as part of a hybrid modeling strategy using simulation for performance analysis. Two major steps have to be carried out in this context. The program which is being investigated has to be translated into a model. During the translation, runtime has to be estimated for numerous computational blocks of statements which are replaced by simple delays. For performance estimation, the model has finally to be analyzed by an evaluation teal. Model evaluation as well as runtime estimation of computational blocks requires values of some variables, the control variables. We discuss the problem of automatic definition of control variables in general and consider some important cases. For the implementation of a model generating tool, we concentrate on parallel Fortran programs using message passing primitives for processes communication.

Clusters of networked commercial, off-the-shelf (COTS) workstations are presently used for computation-intensive tasks that were typically assigned to parallel computers in the past. However, it is hardly possible to predict the timing behavior of such systems or to give guarantees about execution times. In this paper we show how our SONiC(Shared Objects Net-interconnected Computer) system can control timing and partitioning of a workstation as a step towards a distributed real-time system built from COTS components. SONiC provides a class-based programming interface for creation of replicated shared objects of arbitrary, user-defined sizes. Weak consistency protocols are employed to improve system's performance. Our Scheduling Service ensures the requested interactive behavior of a workstation while simultaneously giving a specified number of CPU cycles to parallel tasks. Using off-line scheduling methods we are able to implement real-time Guaranteed Services on COTS workstations.

Cluster computing provides an attractive solution as a low cost parallelcomputing platform consisting of multiple interconnected workstations through commodity network technology as a replacement for an expensive parallel computer. Recent advances in processor technologies made it possible to build a cluster of multi-processor machines more economically usually with Symmetric Multi-Processors. In cluster computing, message passing has been the most widely used programming method due to its simple and efficient programming model and the availability of the programming tools such as Message Passing Interface (MPI). On the other hand, Java technologies have also gained attention as an alternative platform for distributedcomputing thanks to its platform neutral features. In this paper, we present a java based portable parallel runtime system for cluster computing called VCluster and describe its architecture and features.

parallelcomputing on clusters of workstations is receiving much attention from the research community. Unfortunately, many aspects of parallelcomputing over this parallelcomputing engine is not very well understood. Some of these issues include the workstation architectures, the network protocols, the communication-to-computation ratio, the load balancing strategies, and the data partitioning schemes. The aim of this paper is to assess the strengths and limitations of a cluster of workstations by capturing the effects of the above issues. This has been achieved by evaluating the performance of this computing environment in the execution of a parallel ray tracing application through analytical modeling and extensive experimentation.

Quality Critical Decentralised Applications (QCDApp) have high requirements for system performance and service quality, involve heterogeneous infrastructures (Clouds, Fogs, Edges and IoT), and rely on the trustworthy collaborations among participants of data sources and infrastructure providers to deliver their business value. The development of the QCDApp has to tackle the low-performance challenge of the current blockchain technologies due to the low collaboration efficiency among distributed peers for consensus. On the other hand, the resilience of the Cloud has enabled significant advances in software-defined storage, networking, infrastructure, and every technology;however, those rich programmabilities of infrastructure (in particular, the advances of new hardware accelerators in the infrastructures) can still not be effectively utilised for QCDApp due to lack of suitable architecture and programming model.

computing potential is wasted and idle not only when applications are executed, but also when a user navigates by Internet. To take advantage of this, an architecture named Parasite has been designed in order to use distributed and networked resources, without disturbing local computation. This is the working principle of certain global computing projects, but our development introduces new ideas with respect to user intervention, the distributed programming paradigm or the resident software on each user's computer. The project is based on developing software technologies and infrastructures in order to facilitate Web-based distributedcomputing. This paper outlines the most recent advances in the project, as well as discussing the architecture developed and an experimental framework that would validate this infrastructure.

The composition and performance of music is a plural activity that combines the outcomes of a number of procedures, many of which involve functions that operate in parallel. in terms of sound-synthesis operations, a significant number of generative and signal-processing operations involve a combination of concurrent elements, ranging from the production of simultaneous notes by a single instrument to the superimposition of totally independent outputs, where a number of different components contribute to the audio spectrum. The traditional computer processor is a serial device, restricted for the most part to the execution of instructions as a single stream of events. Thus processes that require the aggregation of functions executed in parallel must be simulated by some means of cyclical tasking and data accumulation. In the case of digital audio synthesis and signal processing applications, the resultant effects on overall processor performance quickly become significant, thus limiting the number of individual components that can be handled in real time. About ten years ago, the Music Technology Group at the University of Durham started a series of investigations into the construction of computing architectures for audio applications that embraced a significant degree of true parallelism, based in the first instance on the INMOS Transputer. This article describes some of the most important outcomes of this particular Line of investigation, and highlights aspects that hold a particular relevance for future designs of parallel audio processors.
