Stxxl provides an stl replacement using an abstraction layer to storage devices to allow for the optimal layout of data structures. this allows for multi-terabyte datasets to be held and manipulated in standard c++ data structures, whilst abstracting the complexity of managing this behaviour efficiently. stxxl utilises multi-disk i/o to speed up i/o bound calculations. stxxl has been developed at the university of karlsruhe.
