I suppose that the colvar configuration syntax has changed since NAMD 2.6.
That having said, you need to switch to a newer Version of NAMD. If you have
problems getting the newer version itself to run, post what error you get
exactly, so we can help you at this point.

Betreff: namd-l: Colvar cannot be ran on supercomputer newton
Dear NAMD users,
I want to use SMD to explore the pathway of a channel, using colvar to
restrain the atom in the xy plane, I ran my configuration file on my
computer using NAMD 2.8 multicore 32, it seems working fine. However, when I
use supercomputer newton, the error shows up. The NAMD in the supercomputer
is 2.6-mpi, the .log file shows as following:
Charm++> Running on MPI version: 2.1 multi-thread support: MPI_THREAD_SINGLE
(max supported: MPI_THREAD_SINGLE)
Charm warning> Randomization of stack pointer is turned on in Kernel, run
'echo 0 > /proc/sys/kernel/randomize_va_space' as root to disable it. Thread
migration may not work!
Charm++> cpu topology info is being gathered.
Charm++> 2 unique compute nodes detected.

p.s. I also tried the new installed 2.9, the NAMD doesn't even run.
If anyone had such experience before?
