[gmx-users] Platform-specific differences in grompp's .tpr output

This concerns the water simulation from the tutorial and GROMACS 3.2 with
I've been running the simulation on three different platforms:
Red Hat Linux 7.1 on i686 (i686-pc-linux-gnu)
The issue is that grompp produces a slightly different .tpr file on each
of these platforms. Consequently, the mdrun results (ie. water.trr,
water_out.gro) from each .tpr file are also slightly different. Is this
to be expected from varying platforms?
I ran the same simulation using GROMACS 3.1.4 before, and the odd thing is
that grompp produced the same .tpr file on IRIX64 and OSF1 (I compared
their md5 sums). The one produced on Linux was different, however. Was
this just coincidence??
Any comments/suggestions are appreciated. Thanks.
Please let me know if you want to see the .tpr files and results.
