If we can get the wording for that right... I think the current sentence was intended as an easier alternative to that. Rajeev

Do we want to further clarify that there is no padding of structures etc? Or is that clear already? -- Rob

Alexander Supalov pointed out to me that the following sentence in the MPI-2 I/O chapter, under external32 data representation, pg 250 lines 24-25 is misleading:

"All data items are stored contiguously in the file."

It is intended to mean that there is no prescribed alignment in the resulting file (to word boundary, etc.). But the data is stored contiguously only as long as the file view is contiguous. Accordingly, we propose to clarify the sentence as follows, with the additional text in parenthesis:

"All data items are stored contiguously in the file (if the file view is contiguous)."
