    Hi all,

    Is it possible to use STXXL with MPI? Can anyone please give a light upon this with an example scenario?

    - how to address disk access in .stxxl?
    - how to make? etc.

    Stxxl has been successfully used with MPI (for communication between different nodes) and thread parallelism (to exploit all the cpu cores of a node) in the DEMSort project. http://sortbenchmark.org/demsort.pdf

    The scratch files specified in your .stxxl cannot be shared by different processes any can only be accessed from the local node.
