Steve,
One of the problems with the post-processing is that the particle data in the dump file is not written in order of particle number when running on several CPU's.
This implies that one of the post-processing steps involves sorting the data in the dump file into several per-particle files. This steps actually takes a long time and
it would be very helpful if it were possible to have the dump file contain particle data ordered by particle number.
Do you think this would be possible?
Cheers,
Maurice

it should be already implemented in the current codebase.
try: dump_modify dumpid sort id

Thanks Axel,
Now, would there also be a way to control the precision of the data written to the dump file? We are dealing with very large files (long simulations) and limiting the precision of the data in the dump file could save us significant disk space.

why not use the xtc trajectory format then?
that is much more compact and has internal compression.

See the dump_modify format command.
