Hi Andrew,
Thank you for your attempt to help me.
>Did you see one line of that "Info: Running on ..." line, or multiple instances? If you see multiple of them, it is very likely you have started multiple instance of NAMD accidentally.
No, I don't have such line in my log files.With "Running on ... " I have the following message
Charm++> Running on 1 unique compute nodes (28-way SMP).Charm++> cpu topology info is gathered in 0.019 seconds.
Charm++> Running on 1 unique compute nodes (28-way SMP).
Charm++> Running on 1 unique compute nodes (28-way SMP).
Info: NAMD 2.11 for Linux-x86_64-verbs-smp
Below is a command line I use to start NAMD calculation
sbatch -n 16 --time=0-22:30:00 ompi --bind-to none namd2 <configfile>
Is it right?Thank you.Alexey

Hi Alexey,
We will need more information to help you out. Did you see one line of that "Info: Running on ..." line, or multiple instances? If you see multiple of them, it is very likely you have started multiple instance of NAMD accidentally.
Please be aware that NAMD built for different platforms should be launched in different ways. For example, if you are using Linux-x86_64-multicore built, you should launch NAMD by:
namd2 +p<procs> <configfile>
However, if the NAMD built you have is Linux-x86_64-ibverbs, you should launch it by:
charmrun namd2 ++local +p<procs> <configfile>
If you are using Linux-x86_64-verbs instead, the command to use is:
charmrun +p<procs> ++mpiexec namd2 <configfile>
(All the above examples assumed you are running NAMD on a single Linux node.)Please refer to "notes.txt" that come with the NAMD binaries for details. If you are confused which NAMD built you are, you should able to find it by looking at the first "Info:" line of your log file. In my case, it wrote: "Info: NAMD 2.11 for Linux-x86_64-ibverbs".
Let us know if you still have difficulties.

Subject: Re: namd-l: log file Hi,thanks for the quick response.
I have the following lines in my log file
Info: Running on 1 processors, 1 nodes, 1 physical nodes.
and I am not trying to launche multiple copies.

I usually get this when I have multiple NAMD instances writing to the same file. Can you check how you launched it to make sure that it's consistent with what you want? Look for this line in the output:
Info: Running on XX processors, YY nodes, ZZ physical nodes.
If you are explicitly running multiple copies with +replicas, use the +stdout flag as well.

Dear NAMD experts,
can anybody expalin me why at the minimzation/anneling process I got such jumps step by step in my log file (for exmple, see below 34200, 45920, 43560, 33800, 43880). Thank you in advance.Alexey
