In this thesis, the focus is on the development of scheduling algorithms for Sim-PETEK which is a framework for parallel and distributed execution of simulations. Since it is especially designed for running parameter sweep applications in a heterogeneous distributed computational environment, multi-round and adaptive scheduling approaches are followed. Five different scheduling algorithms are designed and evaluated for scheduling purposes of Sim-PETEK. Development of these algorithms are arranged in a way that a newly developed algorithm provides extensions over the previously developed and evaluated ones. Evaluation of the scheduling algorithms is handled by running a Wireless Sensor Network (WSN) simulation over Sim-PETEK in a heterogeneous distributed computational system formed in TUBITAK UEKAE ILTAREN. This evaluation not only makes comparisons among the scheduling algorithms but it also and rates them in terms of the optimality principle of divisible load theory which mentions that in order to obtain optimal processing time all the processors used in the computation must stop at the same time. Furthermore, this study adapts a scheduling approach, which uses statistical calibration, from literature to Sim-PETEK and makes an assessment between this approach and the most optimal scheduling approach among the five algorithms that have been previously evaluated. The approach which is found to be the most efficient is utilized as the Sim-PETEK scheduler.

Implementation of concurrent constraint transaction logic and its user interface Altunyuva, Fethi; Karagöz, Pınar; Department of Computer Engineering (2006) This thesis implements a logical formalism framework called Concurrent Constraint Transaction Logic (abbr.,CCTR) which was defined for modeling and scheduling of workflows under resource allocation and cost constraints and develops an extensible and flexible graphical user interface for the framework. CCTR extends Concurrent Transaction Logic and integrates with Constraint Logic Programming to find the correct scheduling of tasks that involves resource and cost constraints. The developed system, which integ...
A simulation tool for mc6811 Sarıkan (Tuncer), Nazlı; Güran, Hasan; Department of Electrical and Electronics Engineering (2004) The aim of this thesis study is to develop a simulator for an 8-bit microcontroller and the written document of this thesis study analyses the process of devoloping a software for simulating an 8 bit microcontroller, MC68HC11. In this simulator study a file processing including the parsing of the assembler code and the compilation of the parsed instructions is studied. Also all the instruction execution process containing the cycle and instruction execution and the interrupt routine execution is observed th...
Test driven development of embedded systems İspir, Mustafa; Bilgen, Semih; Department of Electrical and Electronics Engineering (2004) In this thesis, the Test Driven Development method (TDD) is studied for use in developing embedded software. The required framework is written for the development environment Rhapsody. Integration of TDD into a classical development cycle, without necessitating a transition to agile methodologies of software development and required unit test framework to apply TDD to an object oriented embedded software development project with a specific development environment and specific project conditions are done in ...
Design and implementation of a plug-in framework for distributed object technologies Kadıoğlu, Koray; Doğru, Ali Hikmet; Department of Computer Engineering (2006) This thesis presents a framework design and implementation that enables run-time selection of different remote call mechanisms. In order to implement an extendable and modular system with run-time upgrading facility, a plug-in framework design is used. Since such a design requires enhanced usage of run-time facilities of the programming language that is used to implement the framework, in this study Java is selected because of its reflection and dynamic class loading facilities. A sample usage of this frame...
Implementation and simulation of mc68hc11 microcontroller unit using systemc for co-design studies Tuncalı, Cumhur Erkan; Aşkar, Murat; Department of Electrical and Electronics Engineering (2007) In this thesis, co-design and co-verification of a microcontroller hardware and software using SystemC is studied. For this purpose, an MC68HC11 microcontroller unit, a test bench that contains input and output modules for the verification of microcontroller unit are implemented using SystemC programming language and a visual simulation program is developed using C# programming language in Microsoft .NET platform. SystemC is a C++ class library that is used for co-designing hardware and software of a system...
