210. Compiling CPMD on Debian Wheezy

[To those coming here from cpmd.org -- I wasn't meant to post in the bug tracking section, but unfortunately I also can't delete posts]

Here's how to compile cpmd on Wheezy. CPMD is the standard implementation of ab initio Carr-Parrinello method for molecular dynamic and would thus be useful to have at hand.

It took a fair while to hammer out the method, so this post might not read very well. Right now I'm having crashes after the binary has been running for a while -- this point towards system resources more than anything else.


WARNING:
 This involves patching a file -- you never know IF that causes problems with the output. To the best of my knowledge, it should be safe.

There's no reason to think that Ubuntu and Linux mint won't work just as well (i.e. you may want to look here if you're trying to compile for Ubuntu or Mint)

Errors I encountered on the road are found at the end of the post together with solutions.




COMPILING THE BINARY

First you need to request a username and password from http://cpmd.org/. That'll take a few days.

You may have to install libopenmpi-dev libfftw3-dev libblas-dev first

Once your application is approved and you've downloaded your file (in my case cpmd-v3_15_3.tar.gz) copy it to ~/tmp, then

tar -xvf cpmd-v3_15_3.tar.gz
cd CPMD/CONFIGURE

create CONFIGURE/LINUX-x86_64-DEBIAN
     IRAT=2
     CFLAGS='-c -O2 -Wall'
     CPP='/lib/cpp -P -C -traditional'
     CPPFLAGS='-D__Linux -D__PGI -D__GNU -DFFT_FFTW3 -DPARALLEL -DPOINTER8'
     FFLAGS='-c -O2 -fcray-pointer -fno-whole-file -fsecond-underscore'
     LFLAGS='-lfftw3 -lfftw3f -I/usr/include -lblas -llapack -lpthread -lmpi'
     FFLAGS_GROMOS='  $(FFLAGS)' 
      FC='mpif77 -fbounds-check'
      CC='mpicc'
      LD='mpif77 -fbounds-check'


cd ../

Edit the following lines in wfnio.F and change them to:
 15       CHARACTER(len=*) TAG
 63         IF(TAG(1:2).EQ.'NI') THEN
201       IF(TAG(1:2).NE.'NI') THEN
271         IF(TAG(1:2).EQ.'NI') THEN
(See below for the reasons why)

./mkconfig.sh LINUX-x86_64-DEBIAN > Makefile
make -j5

You should now have a working binary. This was a real PITA to sort out.

sudo mkdir /opt/cpmd
sudo chown $USER /opt/cpmd
cp cpmd.x /opt/cpmd


Done! Almost...



Time to get some pseudopotential files from http://cpmd.org/download

Download the following files:
http://cpmd.org/downloadable-files/authentication/contributions/pseudo_std.tar.gz
http://cpmd.org/downloadable-files/authentication/contributions/pseudo_ext.tar.gz
http://cpmd.org/downloadable-files/authentication/contributions/pseudo_vdb.tar.gz
And some test files:
http://cpmd.org/downloadable-files/authentication/contributions/cpmd-test.tar.gz
Put them in /opt/cpmd
cd /opt/cpmd
ls *.gz|xargs -I {} tar xvf {}
echo "export PP_LIBRARY_PATH=/opt/cpmd/PP_LIBRARY" >>~/.bashrc
echo "export PATH=$PATH:/opt/cpmd" >>~/.bashrc.
source ~/.bashrc

Note:
For some reason cpmd refuses to read my pseudopotential files unless I remove the .psp ending. Doesn't matter how eagerly I'm trying to point cpmd in the right direction. You can quickly mv all the psp files like this:
cp /opt/cpmd/pseudo_extlib/*.psp /opt/cpmd/PP_LIBRARY/
cd  /opt/cpmd/PP_LIBRARY/
ls *.psp|sed 's/\./\t/g'|gawk '{print $1}'|xargs -I {} mv {}.psp {}
mv Cu_MT_PBE_SEMI_2.08.psp Cu_MT_PBE_SEMI_2.08
mv Ga.1_GO_LDA.psp Ga.1_GO_LDA
Not that this will guarantee that it'll work. I often find myself putting the full relative path in the .in file:

&ATOMS
*../../PP_LIBRARY/O_MT_PBE KLEINMAN-BYLANDER
LMAX=P
Anyway

Test your binary
cd /opt/cpmd/CPMD-test/vdw
mpirun -n 4 cpmd.x ch4-ch4.inp

Almost completely and utterly done.

There are a few more things to do for a full install:
 1. cpmd2cube
Download cpmd2xyz-scripts.xyz and cpmd2cube.tar.gz and put them in ~/tmp

cd ~/tmp
tar xvf cpmd2cube.tar.gz
cd cpmd2cube/
./Configure  Linux-PC-GFORTRAN-FFTW >Makefile


Edit the Makefile
 11 #--------------- Configuration

 12 FC  = mpif77
 13 FFLAGS  =  -ffree-form -D__GFORTRAN -DFFT_FFTW3 -std=gnu -O2  -fno-whole-file
 14 LFLAGS  =
 15 LIBS    =  -lfftw3

Then compile:
make

cp *.x /opt/cpmd/

2. cpdm2xyz-scripts
tar xvf cpmd2xyz-scripts.tar.gz
mv *xyz.pl /opt/cpmd/

Ergo, it seems to be a problem with the openblas libs -- but they've work just fine with nwchem and gromacs...who knows? It might be due to mixing debian fftw3 and my own openblas.

I compiled openblas according to http://verahill.blogspot.com.au/2012/05/nwchem-with-openblas.html



If you're having problems with the output below it is because fftw 2 and fftw 3 are not compatible and CPDM uses the fftw 2 iface by default.

You can either
1. Install fftw2 (sudo apt-get install fftw-dev, fftw2), and put -l:libfftw.so.2 -l:librfftw.so.2 in your LFLAGS.
or
2. Set -DFFT_FFTW3 instead of -DFFT_FFTW.
