RE: Info: Attempting to read FFTW data from FFTW_NAMD_2.7b1_Linux-Itanium-MPI-Altix.txt

Try to rename all copies of the file
FFTW_NAMD_2.7b1_Linux-Itanium-MPI-Altix.txt, so that the file does not
exist and NAMD cannot find it. You can keep renamed file in case you
need it.
The NAMD should create the correct file on startup if the file is not
present.

 

You should see the following output,

Info: Attempting to read FFTW data from
FFTW_NAMD_2.7b1_Linux-Itanium-MPI-Altix.txt

Info: Optimizing 6 FFT steps. 1... 2... 3... 4... 5... 6... Done.

Friends,

I am a new to NAMD. I submitted a simulation with NAMD. The output file
does not show any error but the last line of it contains the message
'Info: Attempting to read FFTW data from
FFTW_NAMD_2.7b1_Linux-Itanium-MPI-Altix.txt'. The job stops within
seconds. I have pasted below the complete output. Kindly write me what
is going wrong. The NAMD was not compilled from source but from a binary
tarball (NAMD_2.7b1_Linux-Itanium-MPI-Altix.tar.gz)

Charm++> Running on MPI version: 1.2 multi-thread support:
