High performance parallel Java with Javaparty

摘要

To achieve better performance with Java applications, computers can be interconnected with fast networks to form a cluster making available multiple Java Virtual Machines. Unfortunately, Java does not provide an elegant, easy to use mechanism for parallel programming on clusters. JavaParty transparently adds remote objects to Java while avoiding the disadvantages of programming with remote method invocation (RMI) and many disadvantages of the message-passing approach in general. This thesis presents a performance analysis of a cluster running a Java benchmark using JavaParty. It reveals quantitative performance measurements showing a decrease in application execution time by adding more machines. In addition, this thesis presents a method to increase the performance of the cluster network in the presence of network congestion using Quality of Service (QoS).
