Binary identical means that the files are identical bit-for-bit, i.e.
if you ran "cmp traj1.trr traj2.trr" it would report the files to be
the same/indistinguishable.
This is normally only important for debugging. If you don't know it
doesn't apply to you :-)
All that matters for you is that 3.3 >= 3.2, so it should work fine;
the hardware doesn't matter.

Hi Erick,
Thank you for you responce. I am sorry but I dont unterstand the term
"_binary_ identical results". The first simulation was run on a
linux machine
(pentium 4) with gromacs 3.2 from the rpm included in suse. The new
machine
will be (Pentium4 Xeon) with gromacs 3.3 (manual compiled) with
SDSC"s Rocks
clustering system. I think that the architecturesare more or less
the same. I
am correct??? So I could continue the job in the new machine???
Best Regards,
Anthony

Hi Anthony,
As long as the version you're continuing with is the same or more
recent than the one you started with it should work fine; all gromacs
output files are stored in portable formats and are can be read by
newer versions.
You are not guaranteed _binary_ identical results, though - that
depends on the compiler, or if you are running on architectures where
we use tuned assembly loops.
Cheers,
Erik

Hi users:
I have made some simulation in one of our workstation. Now I want
to extend
the simulations few nanoseconds. I can continue the simulations in
other
machine without affecting the results? I need to use the same
gromacs
version?
Best Regards,
Anthony
