A simulation of distributed STM

Abstract

This paper presents an extension of the IaaS Cloud simulator CloudSim. Computational tasks are modeled in the form of a transaction on a transactional memory and communication between the data center is based on the Two-Phase Commit protocol. The model of the distributed STM prototype is implemented using the extended CloudSim simulator. The obtained results are as expected and in accordance with desired system behavior. The presented results are positive and they stimulate future work in development of distributed STM. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no.
