Re: Canonical (External?) Data Representation

Just one precision to what you are saying Albert.
MPI views are dynamic in their nature, and there is not
one-to-one mapping between MPI files and MPI views.
There can even be several views for the same open file
on a given process.
Views are associated with open files when the MPI
application runs, and they are usually different on different
MPI tasks in order to achieve file data partitioning across
tasks. Therefore, in most cases, there is more than one
view associated with an MPI file.
The purpose of the canonical representation of file data is
to maintain persistence of data representation across runs
in different MPI environments.
Therefore, I do not think we can relate canonical representation
to MPI views.
