Right now we're generating one big HDF5 file, and then one to
three .xmf files for the Xdmf grids (time series), which reference
that HDF5 file.

Are you generating one big HDF5 file or one per time step or one per
time step per process?

Hello,
So far we have just used Xdmf/HDF5 and ParaView to view data from
small runs on a single machine, where we generate a time series as
the
simulation progresses by appending snapshots of the data to the same
HDF5 file. As we work towards larger simulations (on a cluster) which
will run much longer, my collaborators are wondering whether we will
be able to view any of the data before the whole run is over? This
could be a snapshot of the current state, or the ability to animate
the data up to the most recent time step, and it wouldn't have to be
an auto-update, as in "Animating Live Data" (although they would like
this ability, too :).
Do any of you have experience checking on your Xdmf/HFD5 data while
it's being generated? And, if so, are there any special tricks to it?
(I know I had trouble reading an HDF5 file one time that I hadn't
closed properly, so I wouldn't be surprised if there are issues
regarding whether the file is closed between writes, but I don't know
if there are other issues, too.)
Thanks for the help,
-Eric
