Singularity EOS

A collection of closure models and tools useful for multiphysics codes

Components

• eos contains the analytic and tabular equation of state infrastructure
• closure contains mixed cell closure models. Currently pressure-temperature equilibrium is supported. Requires eos.
• utils/sesame2spiner converts sesame tables to

To Build

At its most basic:

git clone --recursive git@github.com:lanl/singularity-eos.git
cd singularity-eos
mkdir bin
cd bin
cmake ..
make

To Make tests

To build the tests, in the singularity-eos root directory, clone singularity-eos-data, which is a git-lfs directory. First you need to install git-lfs. This only needs to be done once. Download git-lfs via, e.g.,

apt install git-lfs

and then add the requisite files into your home directory via

git lfs install

Then, in the singularity-eos root directory:

git clone git@gitlab.lanl.gov:singularity/singularity-eos-data.git
mkdir -p bin
cd bin
cmake -DSINGULARITY_BUILD_TESTS=ON ..
make -j
make test

Build Options

A number of options are avaialable for compiling:

Option	Default	Comment
SINGULARITY_USE_HDF5	ON	Enables HDF5. Required for SpinerEOS, StellarCollapseEOS, and sesame2spiner
SINGULARITY_USE_FORTRAN	ON	Enable Fortran API for equation of state
SINGULARITY_USE_KOKKOS	OFF	Uses Kokkos as the portability backend. Currently only Kokkos is supported for GPUs.
SINGULARITY_USE_EOSPAC	OFF	Link against EOSPAC. Needed for sesame2spiner and some tests.
SINGULARITY_USE_CUDA	OFF	Target nvidia GPUs via cuda. Currently requires Kokkos.
SINGULARITY_USE_KOKKOSKERNELS	OFF	Use Kokkos Kernels for linear algebra. Needed for mixed cell closure models on GPU
SINGULARITY_BUILD_CLOSURE	ON	Builds mixed cell closure machinery for multi-material problems
SINGULARITY_BUILD_TESTS	OFF	Build test infrastructure.
SINGULARITY_TEST_SESAME	OFF	Test the Sesame table readers
SINGULARITY_TEST_STELLAR_COLLAPSE	OFF	Test the Stellar Collapse table readers
SINGULARITY_BUILD_SESAME2SPINER	OFF	Builds the conversion tool sesame2spiner which makes files readable by SpinerEOS
SINGULARITY_BUILD_STELLARCOLLAPSE2SPINER	OFF	Builds the conversion tool stellarcollapse2spiner which optionally makes stellar collapse files faster to read
SINGULARITY_INVERT_AT_SETUP	OFF	For tests, pre-invert eospac tables.
SINGULARITY_BETTER_DEBUG_FLAGS	ON	Enables nicer GPU debug flags. May interfere with in-tree builds as a submodule
SINGULARITY_HIDE_MORE_WARNINGS	OFF	Makes warnings less verbose. May interfere with in-tree builds as a submodule
SINGULARITY_SUBMODULE_MODE	OFF	Sets cmake flags for in-tree builds
