On mpich's discussion list the point was made that libraries like HDF5
and (Parallel-)NetCDF provide not only the sort of platform
portability Eric desires, but also provide a self-describing file format.

But I do not agree with that.
If MPI
ce no conversion shall be done, but under 32bits
architectures, there shall be some io performance losts, since more
conversions will occur
Thanks for helping me understand!

I recommend using vader for CMA. It has code to get around the ptrace
setting. Run with mca_btl_vader_single_copy_mechanism cma (should be the
default).
Ok, I tried it, but it gives exactly the same error message!
