To compile with support for HDF5_ output (highly recommended), you will
need to have HDF5 installed on your computer. The installed version will
need to have been compiled with the same compiler you intend to compile
OpenMC with.
OpenMC with. HDF5_ must be built with parallel I/O features. An example
of configuring HDF5_ is listed below::
FC=/opt/mpich/3.0.4-gnu/bin/mpif90 CC=/opt/mpich/3.0.4-gnu/bin/mpicc \
./configure --prefix=/opt/hdf5/1.8.11-gnu --enable-fortran \
--enable-fortran2003 --enable-parallel
* PETSc_ for CMFD acceleration
To enable CMFD acceleration, you will need to have PETSc_ installed on
your computer. The installed version will need to have been compiled with
the same compiler you intend to compile OpenMC with.
To enable CMFD acceleration, you will need to have PETSc_ (3.4.2 or higher)
installed on your computer. The installed version will need to have been
compiled with the same compiler you intend to compile OpenMC with. OpenMC
requires PETSc_ to be configured with Fortran datatypes. An example of
configuring PETSc_ is listed below::
./configure --prefix=/opt/petsc/3.4.2-gnu --download-f-blas-lapack \
--with-mpi-dir=/opt/mpich/3.0.4-gnu/ --with-shared-libraries=0 \
--with-fortran-datatypes
The BLAS/LAPACK library is not required to be downloaded and can be linked
explicitly (e.g., Intel MLK library).
