[svn-r4592] Purpose:

    New addition
Description:
    Initial version of the Parallel I/O performance measurement program.
    Not fully implemented yet but checking them in before I may destroy
    them by accident.
    Don't run this in small file system (like AFS or eirene) since it
    generates gigabytes test files.
Platforms tested:
    modi4 64bits.  It compiled and ran but took a long time because
    the current test parametes are too "wild".
