Implementação de um Mecanismo de Recuperação por Retorno para o Ambiente de Computação OurGrid

OurGrid is a middleware that supports the execution of applications on resources available in a grid. A central node performs the scheduling and control of applications, which makes it a critical element in the system in case of faults. Aiming to decrease the loss of computation caused by crash failures of the central node, we propose an implementation of a rollback recovery mechanism. The overhead of this mechanism on the OurGrid scheduler is assessed in scenarios with various characteristics.
