“…In early days they were created by partitioning the circuit into smaller parts by node or branch tearing [20], [21]. Nowadays, the circuit matrix is created in parallel [22]. The main limitation of this approach is the communication overhead that puts an obstacle of the maximum speed-up of the simulation in this way: "The maximum speed-up obtained with parallel system of N processors that has α % of communication overhead can be no greater than 1/(1α*100)".…”

In this paper, we apply artificial neural networks (ANNs) to the diagnosis of a mixed-mode electronic circuit. In order to tackle the circuit complexity and to reduce the number of test points hierarchical approach to the diagnosis generation was implemented with two levels of decision: the system level and the circuit level. For every level, using the simulation-before-test (SBT) approach, fault dictionary was created first, containing data relating the fault code and the circuit response for a given input signal. Also, hypercomputing was implemented, i.e. we used parallel simulation of large number of replicas of the original circuit with faults inserted to achieve fast creation of the fault dictionary. ANNs were used to model the fault dictionaries. At the topmost level, the fault dictionary was split into parts simplifying the implementation of the concept. During the learning phase, the ANNs were considered as an approximation algorithm to capture the mapping enclosed within the fault dictionary. Later on, in the diagnostic phase, the ANNs were used as an algorithm for searching the fault dictionary. A voting system was created at the topmost level in order to distinguish which ANN output is to be accepted as the final diagnostic statement. The approach was tested on an example of an analog-to-digital converter

“…As for modeling tools, the closest competitor of ICOMM WebALLTED is GridModelica [1] and pAlecsis [6] but they lack workflow capabilities and have weaker mathematical background. The closest analog of a service-oriented workflow management system is Taverna Workbench [4] but it is not primarily designed for remote web access, has its own (non-standard) orchestration language and is not tailored for engineering simulation.…”

This paper presents a multi-layered architecture of computer simulation software capable of utilizing grid and cloud resources, characterized in that the functionality of the system is distributed according to a service-oriented approach, and the system supports the execution of custom user-defined computing scenarios in grid or in cloud (by web services orchestration with an adherence to existing standards) but hides the complexity of direct web services management from the user with the help of the abstract workflow model and a web-accessible problem solving environment with a graphical workflow editor.

“…10 Given a certain application, to be efficiently distributed on an existing computing infrastructure, a grid framework of this kind is required. For example, Andjelković et al 11 describe the parallelization of the simulation of electronic circuits and systems, as well as the development of a grid interface. Furthermore, Evans et al 12 has developed a platform that enables programming parallel and distributed DES simulations, either by parallelizing multiple executions of a given simulation or by the implementation of a distributed DES.…”

Decision-making on discrete event systems with alternative structural configurations is a field with application to the efficient design and operation of many systems, ranging from manufacturing facilities to communication networks. The solution of this problem may be afforded by its transformation into an optimization problem. A variety of statements for this optimization problem can be presented by using different formalisms able to describe the model of the system. These different statements allow developing diverse optimization algorithms for solving the problem, which may be very demanding for a computer. In this paper, several approaches are presented in order to reduce the computing requirements needed by the mentioned algorithms, some of them are implemented in one processor and others are based on distributed computing. In particular, this paper presents a new distributed methodology, which associates sets of alternative structural configurations of the system to different alternative aggregation Petri net (AAPNs), regarding the number of available processors. Under certain conditions, this methodology alleviates the computational requirements for every processor and speeds up the optimization process. A case-study is presented and different techniques are applied to solve it, for illustrating diverse distributed and non-distributed methodologies, regarding the available processors, as well as for comparing their relative performance.
