Edgar and Christoph,
i do not think ROMIO supports this yet.
from ompi/mca/io/romio/romio/README
"This version of ROMIO includes everything defined in the MPI I/O
chapter except support for file interoperability [...]"
i also ran ompi/mca/io/romio/romio/test/external32.c :
on a x86_64 box (litt
the way you launch the app, you will be using ROMIO, and I am not 100%
sure about how the data representation stuff is integrated with OMPI. I
am pretty sure that we are not doing the right thing for OMPIO, but I
will look into later this week.
Thanks
Edgar

Hello,
It seems for me that the endianness is wrong in Open MPI's I/O for the
external32 data representation. :O
Find attached my test programs which write the integer -30 and the double 16.25
into a file.
Here the output on my Linux system:
mpicc c-xdr.c -o c-xdr
mpicc mpi-io-extern
