  • @redies Please try if this works and solves your performance issue. To use the code you have to

    1. put a call to sync_eig before and after the code section in which there is only read access
    2. compile with CPP_MPI3 (probably this could also be used to mask the sync_eig call)

    Then we switch from passive sync (locks) to active sync (fence).
