Examples needed for a system of handlers. Looking at mcs.anl.gov two manipulations look promising, MPI_MODE_UNIQUE_OPEN and MPI_MODE_SEQUENTIAL. However, most of the entries are tagged as deprecated. Can anyone suggest examples I can look at of file systems that allow users to open and close files which may be unique but also may be shared?
