Installation: External Libraries - hyschive/gamer-fork GitHub Wiki
GAMER supports both FFTW2 and FFTW3 for various calculations (e.g., the root-level Poisson solver).
Follow the installation instructions on the FFTW website.
Note that it must be configured with
floating-point type prefix --enable-type-prefix for FFTW2
and MPI support --enable-mpi for both FFTW2 and FFTW3.
Here are example installation scripts using the GNU compiler for FFTW2 and FFTW3, respectively:
export FFTW_PATH=PATH_TO_INSTALL_YOUR_FFTW
export CC=gcc
export F77=gfortran
export CFLAGS=-O3
export FFLAGS=-O3
make clean
./configure --enable-mpi --enable-type-prefix --prefix $FFTW_PATH --enable-float
make
make install
make clean
./configure --enable-mpi --enable-type-prefix --prefix $FFTW_PATH
make
make installexport FFTW_PATH=PATH_TO_INSTALL_YOUR_FFTW
export CC=gcc
export F77=gfortran
export CFLAGS=-O3
export FFLAGS=-O3
make distclean
./configure --enable-openmp --enable-mpi --enable-shared --prefix $FFTW_PATH --enable-float
make
make install
make distclean
./configure --enable-openmp --enable-mpi --enable-shared --prefix $FFTW_PATH
make
make install
GAMER uses GRACKLE for the chemistry and radiative processes. Follow the installation instructions in the GRACKLE website.
Grackle and GAMER can be compiled with different floating-point precisions. It is recommended to compile Grackle in double precision:
> make precision-64
When enabling OpenMP in GAMER (i.e., with the compile-time option --openmp), GRACKLE must be configured with OpenMP support as well using
> make omp-on
GAMER uses HDF5 for storing snapshots.
It is not necessary to enable either --enable-cxx or --enable-parallel when
configuring HDF5 since GAMER currently adopts the C interface with serial I/O.
Here is an example installation script using the icc compiler
(remember to replace PATH_TO_INSTALL_YOUR_HDF5 with your installation path):
CC=icc ./configure --prefix=PATH_TO_INSTALL_YOUR_HDF5
make
make installGAMER uses libyt for in situ Python analysis. See In Situ Python Analysis for details.
libyt has two modes, normal mode and interactive mode. Please refer to libyt -- How to Install.
Set LIBYT_PATH to the folder that contains subfolders include and lib.
