A viewer tool for multi-active object

International audienceActive object is a concurrency design pattern, which is based on allocating a singlethread and control for each independent activity. However today in the era ofmulticore machines using one thread is a great disadvantage. Using a single threadmay also cause deadlocks during the execution. That is why solution calledmultiactive object was presented and implemented in a java library called ProActive.The core idea of this solution is to make these activities multithreaded. In this work Iwill present a tool, which demonstrates the behavior of the multiactive objects basedon the logs made by the library. The main purpose of the tool is to help users to debugtheir applications. Several use cases will be presented revealing main features of thetool and the way user should use them
