Due to the fall in the price of multicore processors, today's non-dedicated clusters tend to include this kind of hardware in their configurations. However, most current resource managers and job schedulers are optimized with the aim of maximizing the throughput in single-core environments. Additionally, job schedulers balance thread loads without considering such aspects as cache affinity, resource contention or other additional criteria. In the same way, general purpose Operating System schedulers will support requirements like the coexistence of soft-real time, best effort or interactive applications are open questions that need to be addressed carefully. For these reasons, new user interfaces, middlewares, and environments that can fill the gap between the user and the new processor architectures are needed. Our CISNE environment has been extended to take into account issues discussed earlier: the mixture of different types of applications considering the multicore features of current desktop environments.
