Getting execution error

[aaayushg]

Trying to run the example calculations 'erlotinib-water' but getting the following error.

sh: 1: /home/aayush/Documents/NNP-MM/client.py: Permission denied
------------- Processor 0 Exiting: Called CmiAbort ------------
Reason: FATAL ERROR: Error running command for QM forces calculation.

Charm++ fatal error:
FATAL ERROR: Error running command for QM forces calculation.

I have corrected all the paths and have 'rw' permission to each file/folder.

Please make the script executable: chmod u+x /home/aayush/Documents/NNP-MM/client.py

That solves the error. Thanks !
But I'm getting another error which I'm not sure what's missing.

rm: cannot remove '/dev/shm/0/qmmm_0.input.result': No such file or directory

Did you do these commands? export RUNDIR=/dev/shm/$SLURM_JOB_ID/ mkdir $RUNDIR This is to set the temporary directory to some place that exists and is writable. It could be easier to just change this line in your NAMD input file qmBaseDir /tmp

Yes, I am using all the files from github and trying to run a sample calculations (with the files in example). My run_nnp.sh file looks like (script from README):

export RUNDIR=/dev/shm/$SLURM_JOB_ID/
mkdir $RUNDIR
#module load nixpkgs/16.09 intel/2016.4
#module load namd-multicore/2.13
#module load python/3.7.0
python3 /home/aayush/Documents/NNP-MM/server.py >& /home/aayush/Documents/NNP-MM/server.$SLURM_JOBID.log&
sleep 10 # wait to make sure server has initialized first
namd2 +p7 md.conf > namd_out.log

Also, everything's same in md.conf (from example folder)

qmforces on
qmParamPDB qmmm.pdb
qmSoftware custom
XXX change this to absolute path of socket client script
qmexecpath /home/aayush/Documents/NNP-MM/client.py
this should be writeable absolute path on a fast file system (e.g., a RAM disk)
qmBaseDir /dev/shm/
QMColumn occ
qmChargeMode none
qmElecEmbed off

The commands to set the temporary directory aren't working. Possibly, this is because your queuing system is not setting the SLURM_JOBID environment variable (are you running this through a SLURM queuing system?). Alternatively, this could be because the /dev/shm directory is not available or writable by you on this system. It is impossible for me to know this. I would recommend talking to your system administrator for assistance. It is likely that /tmp will exist on all systems, so the simplest solution is to follow my previous suggestion of changing this line in the NAMD input file to direct to /tmp instead: qmBaseDir /tmp

Thanks for your prompt replies. I'm not running it using slurm queue, running it on local machine.
I have now changed the qmBaseDir to /tmp but still getting the error.

Did you start the server daemon before running this command? See the line regarding server.py. Start it. Put in it in the background. Check to see if it is running with ps, then you can run NAMD. You will need to change all the lines involving SLURM because these will only be sensible on a SLURM queuing system.

Yes I start the server.py before running namd and it runs without error.
I get an error when I execute namd2

ERROR: Could not find QM output file!
FATAL ERROR: (unknown error): No such file or directory

What files/lines are having slurm dependency ?

[cnrowley]

The lines of the script that contain $SLURM_JOB_ID need to be changed. These variables are defined by SLURM queuing systems when a job is executed. You need to change them to appropriate values on your local system. *export RUNDIR=/dev/shm/$SLURM_JOB_ID/*mkdir $RUNDIR #module load nixpkgs/16.09 intel/2016.4 #module load namd-multicore/2.13 #module load python/3.7.0 python3 /home/aayush/Documents/NNP-MM/server.py >& /home/aayush/Documents/NNP-MM/server.$SLURM_JOBID.log& As for your new error message; I can't diagnose this problem remotely. I believe your system does not have the correct path, environment variables, or python libraries correctly configured. You should talk to your system administrator for assistance.

Could you suggest what path/env I need to setup for this particular execution ?
Thanks
