Hi,
I see. I built the LAM library with default options, i.e. without "-q
extname". In fact, the program I tested with comes from a software
package. In the this package, all MPI calls are terminated with "_".
Thanks for your help.
Best Regards,
/ST

The AIX compiler folds UPPER case routine names to LOWER case unless you
specify
the "-U" option which "Suppresses lowercase folding of Fortran code", so
(unless
you specify "-U", changing the case from UPPER to LOWER should have no
effect
(you could even call it as "MpI_iNiT" if you wanted to - FORTRAN only,
NOT C/C++).
HOWEVER you have terminated "MPI_INIT" with an underscore ("_") which
you have
removed when you converted the case and this is the problem.
If you built the LAM libraries without '-q extname' (the DEFAULT, same
as '-q
noextname') then the names in the libraries will NOT be terminated with
a '_'.
If you built the LAM libraries with a '-q extname' the names in the
libraries
will have an '_' appended.
I assume you did NOT use '-q extname', in which case you shouldn't have
an '_'
when you call the routines and you shouldn't compile your own code with
'-q
extname'.
Regards
Neil
