Download and Installation

2   Installation

The next section describes how the fortran program, pseudopotentials and python interface can be installed.

If you have a installation using the old CamposASE, it is enough just installing the new python interface, see dacapo python interface.

2.1   dacapo fortran program and pseudopotentials

This section describes how the fortran program and pseudopotential are installed. Current version of the fortran program is 2.7.7.

2.1.1   From RPM

A binary RPM (tested and builded using Pentium 4) can be used to install dacapo on a Pentium 4 system.

This will install pseudopotentials in /usr/share/dacapo/psp and binary executable in /usr/bin.

2.1.2   From Tarfile

A Dacapo tar file containing fortran source code and pseudopotentials can be used to install dacapo on a non rpm system.

Use gunzip Dacapo-2.7.7.tar.gz.

2.1.2.1   Dacapo binaries for different platforms

The page dacapo binaries list dacapo binaries for different platforms.

2.1.2.2   Compling the fortran source code

use:

cd src
gmake <arch> [MP=mpi]

where <arch> is one of:

  • sun_ss10
    Sun sparcstation 10/20)
  • ibm_power3
    RS/6000 power3 node
  • ibm_power2_wide
    RS/6000 wide power2 node
  • ibm_power2_thin
    RS/6000 thin/thin2 power2 node
  • sgi
    Silicon Graphics n32 ABI
  • alpha
    Digital Alpha
  • pglinux
    Portland Group pgf90 compiler on linux
  • intellinux
    Intel ifc Fortran compiler version >=6.0 on Linux
  • pathscale
    Pathscale EKOpath compiler for AMD64 and EM64T

It is important to use the GNU gmake command on many UNIX systems, in stead of the system's own make command which may be incompatible with our Makefile.

More details should follow here...

2.1.2.3   Installing the pseudopotentials

The dacapo fortran program adds the enviroment variable DACAPOPATH to the pseudopotential filename (if the file is not found in the currebt working directiory). Copy all pseudopotentials to a directory and set the DACAPOPATH environment variable to this directory:

cp psp/*/*/*.pseudo /some/directory/
setenv DACAPOPATH /some/directory/

2.2   dacapo python interface

  1. Get the latest version of the dacapo python interface.

    1. From tar file
    2. cvs:
      cvs checkout dacapo/Python

  1. for case 1 unpack the tar file and:

    [home] $ cd Dacapo

    (for case 2 cd dacapo/Python)

  2. and install with the standard setup.py script (if you have root permission):

    [Python] $ python setup.py install

    If you do not have root permission use:

    [Python] $ python setup.py install  --prefix=/some/where/in/your/path

    In this latter case you must set your PYTHONPATH environment variable, as directed by the setup.py script.

  3. Alternative to step 3 simply set the PYTHONPATH environment variable to your cvs directory.

3   CVS access

You can access the code from CVS. See the Campos CVS Page.

After the CVS login, get the dacapo fortran source using:

cvs -d :pserver:USERID@cvs.fysik.dtu.dk:/home/camp/CVSROOT checkout dacapo/src

Get the pseudopotentials using:

cvs -d :pserver:USERID@cvs.fysik.dtu.dk:/home/camp/CVSROOT checkout dacapo/psp

Get the Python interface using:

cvs -d :pserver:USERID@cvs.fysik.dtu.dk:/home/camp/CVSROOT checkout dacapo/Python

4   Running Dacapo in parallel

Dacapo can run in parallel using the MPI parallel library. You need to compile a parallel executable:

gmake <arch> MP=mpi

For getting dacapo to work in parallel with ASE you need to make a script dacapo.run, which should be executable and in your path. dacapo.run is an example of such a script. This example use the LAM/MPI and the PBS batch system.

If you do not use a batch system you can replace the line:

MACHINEFILE=$PBS_NODEFILE

with a explicit file containing the names of the nodes, one on each line:

MACHINEFILE=/your/machine/file

5   Notes for installation on specific computers

5.1   Opteron (pathscale compiler)

This build assumes you have the Pathscale Fortran compiler, the OpenMPI message passing library and the ACML library installed. Below follows details on how to build the NetCDF and FFTW libraries needed by dacapo.

5.1.1   NetCDF (Network common Data Format)

Download the NetCDF sofware

Build netcdf like this:

tar -zxf netcdf-3.6.1.tar.gz
cd netcdf-3.6.1/src
./configure --prefix=/usr FC=pathf90 FCFLAGS=-byteswapio CC=pathcc CXX=pathCC
make

and then install in /usr running as root:

make install

See also niflheim note on building a netcdf RPM.

5.1.2   FFTW (Fast Fourier Transform library)

Download version 2.1.5 here Build FFTW like this:

tar -zxf fftw-2.1.5.tar.gz
cd fftw-2.1.5
./configure F77=pathf90 CC=pathcc CFLAGS=-O3 FFLAGS=-O3
make

and then as root:

make install

This will install FFTW in /usr/local.

5.1.3   dacapo

Unpack the dacapo tar-file:

tar -xzf dacapo-2.7.7.tar.gz
cd dacapo-2.7.7/src

Set the environment variables for ACML, NETCDF and FFTW:

setenv ACML /opt/acml3.5.0/pathscale64
setenv NETCDF /usr/local
setenv FFTW /usr/local

Select the location of the MPI library which you want to use. The default is to use the MPI library installed in /usr as set by:

setenv MPIDIR /usr

Alternative locations may be specified, for example:

setenv MPIDIR /usr/local/infinipath-1.3.1

Now compile dacapo (serial and parallel):

make pathscale
make pathscale MP=mpi

Ignore warnings about type mismatch when compiling ms.F, this is due to MPI expecting pointers to integer arrays for all data types.

Now copy the compiled executables to somewhere on your path, e.g.:

cp pathscale_serial/dacapo.run /usr/local/bin/dacapo_<version>.run
cp pathscale_mpi/dacapo.run /usr/local/bin/dacapo_<version>_mpi.run

5.2   OpenMPI

For dacapo to run together with ASE you need a dacapo.run script in your path, that will start the correct dacapo executable. This OpenMPI dacapo.run script assumes you are running OpenMPI using the PBS batch system.

You might have to edit the location and names of the serial and parallel executable in this script, i.e the lines:

# Name of serial and parallel DACAPO executables
DACAPOEXE="dacapo_2.7.7.run"
DACAPOEXE_PAR="dacapo_2.7.7_mpi.run"

If OpenMPI is not installed under /usr you will also have to change this in the script.

Copy this script to /usr/local/bin/dacapo.run.

5.3   Portland group compiler

Here we will build using the Portland Group's PGI Workstation version 6.0-5 Fortran compiler, and a precompiled BLAS library from the ATLAS project.

5.3.1   Atlas BLAS

Take a precompiled version (3.6.0) of Atlas that fits you system best. The rest of the installation assumes you have installed ATLAS in /usr/local/lib.

The precompiled version of atlas includes 2 underscore for fortran symbols, so for the rest of the fortran compilations use the pgf90 flag -Msecond_underscore.

5.3.2   NetCDF (Network common Data Format)

Download the NetCDF sofware

Build netcdf like this:

tar -zxf netcdf-3.6.1.tar.gz
cd netcdf-3.6.1/src
./configure --prefix=/usr/local FC=pgf90 FCFLAGS='-byteswapio -Msecond_underscore' CC=pgcc CXX=pgCC CPPFLAGS='-DNDEBUG -Df2cFortran'
make

and then install in /usr running as root:

make install
5.3.3   FFTW (Fast Fourier Transform library)

Download FFTW version 2.1.5 and build FFTW like this:

tar -zxf fftw-2.1.5.tar.gz
cd fftw-2.1.5
./configure --prefix=/usr/local F77=pgf90 CC=pgcc CFLAGS=-O3 FFLAGS='-O3 -Msecond_underscore'
make

Now the root user must give the build-user write-access to /usr/local:

root# chmod 777 /usr/local/lib /usr/local/include /usr/local/info

and then install by:

make install

Finally change back permissions:

root# chmod 755 /usr/local/lib /usr/local/include /usr/local/info
5.3.4   LAM-MPI

We will here use the MPI library LAM-MPI

Download the tarfile and build LAM-MPI using:

tar xzvf lam-7.1.2.tar.gz
cd lam-7.1.2
setenv CPPFLAGS '-DNDEBUG -Df2cFortran'
setenv F77 pgf90
setenv FC  pgf90
setenv FFLAGS '-byteswapio -Msecond_underscore'
./configure --prefix=/usr/local/lam-7.1.2-pgi/ CPPFLAGS='-DNDEBUG -Df2cFortran'  F77=pgf90 FC=pgf90  FFLAGS='-byteswapio -Msecond_underscore'
gmake
gmake install
5.3.5   Dacapo

Get and unpack the Dacapo tar file, and set the environment variables:

tar xzvf Dacapo-2.7.7.tar.gz
cd Dacapo-2.7.7/src
setenv BLASLAPACK '-L/usr/local/lib -llapack -lcblas -lf77blas -latlas'
setenv NETCDF /usr
setenv FFTW /usr
setenv MPIDIR /usr/local/lam-7.1.2-pgi/

and compile like:

gmake pglinux
gmake pglinux MP=mpi
