Hi Roland, Ian, Everyone,<br>
<br>
Thanks for your input. May I add a few points though to elaborate on
my question. Let's assume we run a simulation with 2 MPI processes
(ranks) with each process writing to it's HDF5 own file. Further
assume we have output from 2 restarts on top of the first output,
i.e. we have Simfactory output directories output-0000, output-0001
and output-0002. So, for a variable rho, for instance, we would then
have<br>
output-0000/<parfile>/rho.file_0.h5<br>
output-0000/<parfile>/rho.file_1.h5<br>
<br>
output-0001/<parfile>/rho.file_0.h5<br>
output-0001/<parfile>/rho.file_1.h5<br>
<br>
output-0002/<parfile>/rho.file_0.h5<br>
output-0002/<parfile>/rho.file_1.h5 <br>
<br>
Now, for purposes of visualizing the data, for instance, one would
be interested in collecting all these data chunks into a single
file. The question is how to bundle these into a single file. I
wanted to know if any of the available Carpet tools can help with
this. <br>
<br>
I stand to be corrected, but I seem to recall that some of the
non-ET tools (e.g. SimulationTools) seem to have an abstraction
mechanism for transparently combining CarpetIOHDF5 output from
various checkpoints. Is that the direction I may have to go?<br>
<br>
Thank you,<br>
Dumsani<br>

<br>
there are two different things you may want to do. If you have
files<br>
rho.file_0.h5 eps.file_0.h5 rho.file_1.h5 and eps.file_1.h5
and would<br>
like to combine the variables you can use:<br>
<br>
hdf5_merge rho.file_0.h5 eps.file_0.h5 vars.file_0.h5<br>
hdf5_merge rho.file_1.h5 eps.file_1.h5 vars.file_1.h5<br>
<br>
ie when you want to keep the file_X structure intact. If not
then you<br>
must use the hdf5 slicer:<br>
<br>
hdf5_slicer --out3d-cube rho.file_*.h5 eps.file_*.h5 vars.h5<br>

<div>Also note that (as far as I know) this simply copies the
datasets from one file to the other. It does not coalesce the
individual rectangular components into a single one, suitable
for viewing with a generic visualisation tool. This would not
in general be possible for a mesh-refined grid.</div>
