Automatic generation of profiling libraries


Up: Contents Next: Writing wrapper definitions Previous: Appendices

The profiling wrapper generator (wrappergen) has been designed to complement the MPI profiling interface. It allows the user to write any number of `meta' wrappers which can be applied to any number of MPI functions. Wrappers can be in separate files, and can nest properly, so that more than one layer of profiling may exist on indiividual functions.

Wrappergen needs three sources of input:

    1. A list of functions for which to generate wrappers.
    2. Declarations for the functions that are to be profiled. For speed and parsing simplicity, a special format has been used. See the file proto.
    3. Wrapper definitions.
The list of functions is simply a file of whitespace-separated function names. If omitted, any forallfn or fnall macros will expand for every function in the declaration file.
