Computational Peer-To-Peer (P2P) grids are a cheap and efficient platform to run \"Bag-of-tasks\" parallel applications, consisting of a large number of tasks that do not need to communicate amongst themselves and can be executed independently. When these applications handle a large amount of data, it is crucial that the overhead involved with data transfer does not impact application performance substantially, hindering any benefits that its parallelization can bring. Fortunately, many of these applications have a high rate of data reuse, whether in the same or in successive runs of the application, which allows a caching strategy to be used, so to minimize the loss of performance caused by data movement.
