Hi Jeff,
I will now rebuild LAM_MPI with all of the comipler
options set exactly the same(i.e. FCOPT and CCOPT and
the like all set exactly the same). I am sure now
that this is an XL compiler problem. If I had noticed
the phrase "QIPA" in the output I would have figured
it out because this option is one that requires the
most system resources. I think it involves
optimization across many different object files. If
the build does not go with all of the flags set the
same then I will try the build without the "-qipa"
flags set and at a lower optimization level.
Thanks for your feedback!
