Title: Concurrency and Parallel Methods for multi-core Platforms
Authors: Fredén Jansson, Johannes

Abstract: This master thesis has been written at Saab Electronic Defence Systems. Its main purpose is to evaluate the amount of resources needed to rewrite sequential Java components running in Saabs systems, in such a way that they can take advantage of multi-core processors. The research of the thesis addresses issues with concurrent programming in Java, available frameworks and methods and how they can be implemented for different kinds of applications. The research has been used to parallelize a Saab component called Threat Evaluation and Weapons Allocation (TEWA). As a result of the parallelization, a general purpose concurrency framework, called Concurrent Eventhandling and Loop Parallelization (CELP) framework, has been developed. CELP can be used, together with standard Java concurrency tools, to parallelize more of Saabs event based components, making them scalable and safe. This has been shown with the results of the parallelized TEWA, which includes good scalability, 15 times performance increase compared to the sequential version and improved deterministic behavior.
