        "description": "petgem\n======\n\nPETGEM is a parallel python code for 3D Controlled-Source\nElectromagnetic Method (3D CSEM) in geophysics using high-order edge finite\nelements (N\u00e9d\u00e9lec finite elements).\n\n\nRequirements\n------------\n\nPETGEM is known to run on various flavors of Linux clusters. Its requirements are:\n\n* `PETSc <https://www.mcs.anl.gov/petsc/>`__ (builded version for **COMPLEX-VALUED NUMBERS**) for the use of direct/iterative parallel solvers\n* `Python 3 <https://www.python.org/>`__ (versions 3.5.2 and 3.6.3 have been tested)\n* `Numpy <http://www.numpy.org/>`__ for arrays manipulation\n* `Scipy <http://www.scipy.org/>`__ for numerical operations\n* `Blessings <https://pypi.python.org/pypi/blessings/>`_ for terminal styling and positioning\n* `Sphinx <http://www.sphinx-doc.org>`__ and `LaTeX <https://www.latex-project.org/>`__ (textlive) to generate documentation\n* `Petsc4py <https://bitbucket.org/petsc/petsc4py>`__ for parallel computations on distributed-memory platforms. It allows the use of parallel direct/iterative solvers from `PETSc <http://www.mcs.anl.gov/petsc/>`_\n\nOn Linux, consult the package manager of your preference. PETGEM can be\nused without any installation by running the kernel from the top-level\ndirectory of the distribution.\n\n\nInstall\n-------\n\n* Following commands may require root privileges\n\n* Download `PETSc <https://www.mcs.anl.gov/petsc/>`__ (PETSc 3.7, 3.8, and 3.9 have been tested)\n\n* Uncompress the PETSc archive (in this example, using PETSc 3.9.3)::\n\n  $ tar zxvf petsc-3.9.3.tar.gz\n\n* Configure and build PETSc. The configuration options depend on the calculations you want to perform (complex- or real-valued) as well as your compiler/MPI/Blas/Lapack setup. For PETGEM executions, **PETSC MUST BE BUILD FOR COMPLEX-VALUED NUMBERS**. In order to avoid incompatibilities between PETSC, petsc4py and PETGEM, we highly recommend the following configuration lines. Please, visit PETSc website for advanced configuration options. If you have a clean environment (not working MPI/Blas/Lapack), then run::\n\n  $ cd petsc-3.9.3\n  $ export PETSC_DIR=$PWD\n  $ export PETSC_ARCH=arch-linux2-c-debug\n\n* If you do not want support for MUMPS, run following configure line::\n\n  $ ./configure --with-cc=gcc --with-cxx=g++ --with-fc=gfortran  --download-mpich --download-fblaslapack --with-scalar-type=complex\n\n* If you want support for MUMPS, please add following options to previous configure line::\n\n  $ --download-mumps --download-scalapack --download-parmetis --download-metis --download-ptscotch --download-cmake\n\n* Further, to activate GPUs support, please add following options to previous configure line::\n\n  $ --with-cuda=1 --with_cuda_dir=PATH\n\n  where ``PATH`` is the directory of your CUDA libraries. \n\n* Then, build and install PETSc::\n\n  $ make $PETSC_DIR $PETSC_ARCH all\n  $ make $PETSC_DIR $PETSC_ARCH test\n  $ make $PETSC_DIR $PETSC_ARCH streams\n\n* Ensure your ``mpicc`` compiler wrapper is on your search path::\n\n  $ export PATH=\"${PETSC_DIR}/${PETSC_ARCH}/bin:${PATH}\"\n\n* Ensure you have a Numpy installed::\n\n  $ pip3 install numpy\n\n* And finally, install PETGEM with its dependencies (`Scipy <http://www.scipy.org/>`_ , `Blessings <https://pypi.python.org/pypi/blessings/>`__, `Sphinx <http://www.sphinx-doc.org>`__, `Petsc4py <https://bitbucket.org/petsc/petsc4py>`__) by typing::\n\n  $ pip3 install petgem\n\n\nCitations\n---------\n\nIf PETGEM been significant to a project that leads to an academic\npublication, please acknowledge that fact by citing the project:\n\n* Castillo-Reyes, O., de la Puente, J., Cela, J.
