After configure, you can also edit the <code>config/setup</code> file. You can run the following configure script (named for example <code>yambo_install.sh</code>) which should work for '''yambo 5.0''' on '''Linux machines''':
YAMBO_EXT_LIBS="/user/defined/path/for/internal/libs"
./configure FC=gfortran \
  --with-extlibs-path=$YAMBO_EXT_LIBS \
  --enable-keep-extlibs \
  --enable-time-profile \
  --enable-msgs-comps \
  --enable-keep-src \
  --enable-memory-profile \
  --enable-int-linalg \
  --enable-par-linalg \
  --enable-netcdf-output \
  --enable-slepc-linalg


If you want to install yambo on your local machine or just for testing/tutorial purposes, you can start with the configure options suggested here:
==== Specific Configuration options ====
 
--enable-mpi              # already enabled by default
--enable-open-mp
 
to enable MPI and OpenMP parallelizarion;
 
--enable-time-profile
--enable-memory-profile
 
to enable time and memory profiling (very useful for benchmarking and debugging);
 
--enable-par-linalg
--enable-slepc-linalg
 
to enable rispectively the support to the parallel (with ScaLAPACK) linear algebra and the suport for the diagonalization of BSE using SLEPc library;
 
--enable-cuda=<opts>


to enable CUDA-Fortran support, where <code><opts></code> are the CUDA version and the compute capability of the NVidia device (e.g. <code>cuda11.0,cc70</code>). Please consider this last option only if you are sure that your machine have a GPU CUDA-capable.
Here some info about the different configuration options:
 
* [[configure-suggested|Details on configure options for yambo]]
==== About external libraries ====
 
Usually in HPC systems you can find already installed the library needed by Yambo. So you can use them through the specific configure options. Here below some examples.
 
In order to link to a specific installation of a library you can use the relative configure option and specify the path:
 
--with-hdf5-path=</path/to/hdf5>
--with-netcdf-path=</path/to/netcdf-c>
--with-netcdff-path=</path/to/netcdf-fortran>
 
Here and example on how to use an installation of the Intel MKL libraries for the linear algebra and the Fourier transformations:
 
--with-blas-libs="-L${MKLROOT}/lib/intel64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm -ldl" \
--with-lapack-libs="-L${MKLROOT}/lib/intel64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm -ldl" \
--with-scalapack-libs="-L${MKLROOT}/lib/intel64 -lmkl_scalapack_lp64" \
--with-blacs-libs="-L${MKLROOT}/lib/intel64 -lmkl_blacs_intelmpi_lp64" \
--with-fft-includedir="${MKLROOT}/include" \
--with-fft-libs="-L${MKLROOT}/lib/intel64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm -ldl"
 
==== About environment variables ====
 
Using specific environment variables it is also possible to tell the configuration script the name of the compiler or of the MPI wrapper or other compilation options. Here some examples in case you are using the NVHPC compilers suite:
 
./configure CC=nvc FC=nvfortran FPP="nvfortran -Mpreprocess -E" MPIFC=mpif90 ...

Download

The Yambo source code can be downloaded from several sources. Refer to the dedicated page for further informations.

Quick Configuration (with long compilation)

Yambo can make good use of external libraries like FFTW, LAPACK, netCDF, HDF5, IOTK, LIBXC and so on. It is worth identifying if they are already installed on your system, especially for HPC machines.

If you are lucky, the configure script will successfully find the best compiler options. Moving in the source directory you can configure quickly Yambo and start the compilation simply with these two commands: 

$ ./configure
$ make core

This leads to a very long compilation because Yambo will download and compile all the required libraries. Executables are found in the bin folder. To check that it works:


The simplest install of yambo is the one using internal libraries and compiled with gfortran. This is useful to test the code on your local machine, or in order to easily follow the yambo tutorials. 

$ ./bin/yambo

Cannot access CORE database (SAVE/*db1 and/or SAVE/*wf)

This is the expected error message since we didn't provide the input database needed by Yambo.

Custom Configuration

In general, however, some fine-tuning will be necessary to link the requested libraries. It is also possible to customize the configurazion using configure options that allow you to enable or disable some features. In order to have a complete list of all those options use the command 

$./configure --help

After configure, you can also edit the config/setup file. You can run the following configure script (named for example yambo_install.sh) which should work for yambo 5.0 on Linux machines: 

YAMBO_EXT_LIBS="/user/defined/path/for/internal/libs"
./configure FC=gfortran \
 --with-extlibs-path=$YAMBO_EXT_LIBS \
 --enable-keep-extlibs \
 --enable-time-profile \
 --enable-msgs-comps \
 --enable-keep-src \
 --enable-memory-profile \
 --enable-int-linalg \
 --enable-par-linalg \
 --enable-netcdf-output \
 --enable-slepc-linalg

Specific Configuration options

Here some info about the different configuration options:

Here is a list of specific configuration options.

Known Issues

  • gfortran 4.4 or earlier versions
    Yambo 5.x uses different Fortran constructs, as for example "allocate(x, source=y)", that are not supported by gfortran 4.4 and its earlier versions, please update your gfortran or use a different compiler.
  • NetCDF/HDF5 in Ubuntu 20.4
    Internal NetCDF and HDF5 libraries in LinuxMint 20.1/Ubuntu 20.4 have problems with Yambo please use internal Yambo libraries
  • Quantum-Espresso at GAMMA point
    In Quantum-Espresso if you perform a SCF calculation using the option "KPOINTS gamma" you should use the same option for the NSCF otherwise Yambo gets confused with the g-vectors. If you need more k-points in the NSCF just re-run the SCF with "KPOINTS automatic /1 1 1 0 0 0" and the run NSCF with a finite k-grid
  • Internal MAC-OSX libraries
    At present it is no possible to compile Yambo with internal macos libraries Indeed, no include/system/netcdf.mod file is present in the system. The problem is due to Autoconf setting which automatically searches for versions of the needed libraries in your system despite the specific options given to configure. Then, it would compile the internal hdf5, then find an external netcdf, then try to compile netcdf-fortran creating various conflicts.
  • gfortran compiler on MAC-OSX
    There are different problems compiling Yambo with "gfortran" variant of the compiler/libraries with MacPorts, a possible solution it is to install the "gcc8" variant of these libraries and compilters.
    More details here: http://www.yambo-code.eu/forum/viewtopic.php?t=1767
  • Input file generation on MacOSX
    There are two issues on input file generation: 1) when you generate an input file on MacOSX Yambo is not able to read values already present in the input file, and reset them to the default value; 2) if yambo and ypp have the same option to generate an input file the code get confused. Please use long input strings, for example "yambo -optics" instead of "yambo -o".
  • Parallel compilation with nvfortran for nproc >=8
    Compiling yambo in parallel with nvfortran and 8 or more processor give some problem. Please compile with less processors
