gistfile1.txt

# Packages used:

gsl 1.15  			http://ftp.df.lth.se/pub/ftp.gnu.org/pub/gnu/gsl/gsl-1.16.tar.gz
openmpi 1.6.5			http://www.open-mpi.org/software/ompi/v1.6/
fftw 2.1.5			http://fftw.org/fftw-2.1.5.tar.gz
hdf5 1.6.10			http://www.hdfgroup.org/ftp/HDF5/releases/hdf5-1.6.10/src/
Gadget 2.0.7			http://www.mpa-garching.mpg.de/gadget/


## Compiling prerequisites

GSL:
./configure --prefix=/where/to/install
make
make install



OpenMPI:
./configure --prefix=/where/to/install
(include --enable-static or add /where/to/install to your LD_LIBRARY_PATH)
make all install
add the bin subdirectory of the installation directory to your PATH



FFTW-2.1.5:
for single precision:
./configure --prefix=/where/to/install --enable-mpi --enable-type-prefix --enable-float
make
make install


On OSX 10.8.4, compiling with paths hardcoded in the Makefile worked:

ifeq ($(SYSTYPE),"MPA")
CC       =  mpicc
OPTIMIZE =  -O3 -Wall
GSL_INCL =  -I/path/you/installed/gsl-1.15/include
GSL_LIBS =  -L/path/you/installed/gsl-1.15/lib
FFTW_INCL=  -I/path/you/installed/fftw-2.1.5/include
FFTW_LIBS=  -L/path/you/installed/fftw-2.1.5/lib
MPICHLIB =
HDF5INCL =  -I/path/you/installed/hdf5-1.6.10/include
HDF5LIB  =  -L/path/you/installed/hdf5-1.6.10/lib -lhdf5 -lz
endif



you also have to enable long ids:

OPT   +=  -DLONGIDS



add gadget2 dir to path:

export PATH=$PATH:/path/you/installed/Gadget-2.0.7/Gadget2



run gadget2 on multiple cores (within the handson directory):

mpirun -np 4 Gadget2 param.txt
