[gmx-users] Split Trajectory file into parts

Dear Users,

Simulation writes to a Lustre file system (a distributed file system made
of many hard drives).
About 100 Gb was written in 1 hrs. After a while, gromacs 5.1 says it can't
write the trajectory file.
The file system still has lots of space. Not sure if that was because one
of the many hard drives filled up.

Is it possible to ask gromacs to automatically split the trajectory files
into parts?
Or, I have to write a shell script to make gromacs restart the simulation
every 15 minutes?

Thank you.
