- new preferred API calls for registering MCA parameters are
mca_base_param_reg_{int|string} and
mca_base_param_reg_{int|string}_name.
- See opal/mca/base/mca_base_param.h for docs on new calls.
- Can now register and lookup a value at the same time.
- Can now mark a parameter "read only" at registration time
- Can now mark a parameter "internal" at registration time
- Can now associate a help message with the parameter at registration
time; displayed in the ompi_info output.
The old API calls are still available for backwards compatibility
(mca_base_param_register_{int|string}. They will eventually be
removed -- all developers are encouraged to use the new APIs from here
on out and replace any old calls with the new API.
Some params were also renamed -- the previous convention of using
"base_" as a prefix for any param that was not associated with a
component is henceforth deprecated. Instead, use one of the following
prefixes:
mca: for anything in the MCA base itself
opal: for anything in OPAL
orte: for anything in ORTE
mpi: for anything in OMPI
