Recovery in multithreaded applications using execution monitoring and recovery engine (EMRE)

In today´s cloud computing world, concurrent programming is must for any application. Multithreaded programming represents one aspect of concurrent programming. Multithreaded programming has some advantages like resource utilization and responsiveness but multithreading has its own disadvantages as well, like race condition and deadlock. A deadlock condition in a multithreaded application could lead to application hang. To overcome application hang and to develop a stable and robust multithreaded application, we propose a recovery design paradigm using an execution monitoring and recovery engine (EMRE). EMRE provides recovery over the hang threads in a multithreaded application and prevents application hang. The recovery module increases the stability and fault tolerance capability of the application. At the end, we present a case study of typical multithreaded program to demonstrate the feasibility and practicability of the recovery paradigm using execution monitoring and recovery engine (EMRE).
