600 GB of memory? I highly doubt that you have that much memory
available. Are you sure that this is not a typo? Can you please post
evidence that you have >=600 GB of memory available? It is common for
clusters to disallow an individual process from using >10% of the
total memory on a head-node, which makes 600 MB more likely, in which
case you can try submitting your job to a compute node.

Hello,
thank you for your reply. I have used following command :
g_msd -n POPC.ndx -lateral z -o POPC_msd.xvg -mol POPC_diff.xvg
Trajectory has 10000 frames and the system it was ran on is Fedora Red
Hat 5.4.
Indeed my network administrator was very unhappy about comsumed memory.
Regards,
Slawomir

Hi Slawomir,
That's quite a usage of memory! Can you provide more information? Like
the number of frames in the trajectory, the command line you used, and
the system you ran on?
Cheers,
Tsjerk

Hi GMX Users,
I am writting this email, beacause I think the g_msd program in
Gromacs 4.5.4 bears a problem. I was calculating the MSD od center of
mass of POPC in membrane (system contains 274 POPC lipid molecules in
all-atom force field) from 50 ns trajectory and it seems to consume
great amount of memory. With time of calculations the memory reserves
are gradually devoured to the extent, in my case, of over 600 GB
(than my administrator of cluster killed the process). It seems that
it does not release memory and it's pilling results up with steps in
memory. Have you heard of such case?
Best wishes,
