The emergence of Multi/Many-core systems signified an increasing need for parallel programming. Transactional Memory (TM) is a promising programming paradigm for creating concurrent applications. At current date, the design of Distributed TM (DTM) tailored for non coherent Manycore architectures is largely unexplored. This thesis addresses this topic by analysing, designing, and implementing a DTM system suitable for low latency message passing platforms. The resulting system, named SC-TM, the Single-Chip Cloud TM, is a fully decentralized and scalable DTM, implemented on Intel’s SCC processor; a 48-core ’concept vehicle’ created by Intel Labs as a platform for Many-core software research. SC-TM is one of the first fully decentralized DTMs that guarantees starvation-freedom and the first to use an actual pluggable Contention Manager (CM) to ensure liveness. Finally, this thesis introduces three completely decentralized CMs; Offset-Greedy, a decentralized version of Greedy, Wholly, which relies on the number of completed transactions, and FairCM, that makes use off the effective transactional time. The evaluation showed the latter outperformed the three.
