Hi all, I'm new to gromacs. I have setup a protein MD simulation in a
cluster, I'm using 6 computers with 2 CPUs each one.
After gromacs begun running I had 12 trajectory files in the folder the
output is written:
md.trr
#md.trr.1#
#md.trr.2#
................
#md.trr.11#
It seems like the trajectory is replicated by each CPU the simulation is
running on.
All files has the same size, and grows simultaneously as the simulation
advances.
Is that a normal thing??
Can I delete the #* files??
I infer from your results that you've run 12 single-processor
simulations from the same working directory. GROMACS makes backups of
files when you direct it to write to an existing file, and these are
numbered as #filename.index#. Your 12 simulations are all there, but you
can't assume that those files with number 5 are all from the same
simulation, because of the possibility of filesystem asynchronicities in
creating the files.
If you're trying to run 12 single-processor simulations in the same
working directory, then you need to rethink your strategy. If you're
trying to do something else, then you also need to rethink :-)
