ODEPACK
These Fortran solvers tackle the initial value problem for ODE systems. The collection includes solvers for systems given in both explicit and linearly implicit forms.
Quantum Molecular Dynamics
A new algorithm for use with first-principles molecular dynamics codes enables the number of atoms simulated to be proportional to the number of processors available.
Serpentine Wave Propagation
These methods for solving hyperbolic wave propagation problems allow for complex geometries, realistic boundary and interface conditions, and arbitrary heterogeneous material properties.
DOE funds LLNL project to improve differentiation of extreme-scale science apps
Researchers will address the challenge of efficiently differentiating large-scale applications for the DOE by building on advances in LLNL’s MFEM finite element library and MIT’s Enzyme AD tool.
Developing technology to keep the nuclear stockpile safe, secure, and reliable
The first article in a series about the Lab's stockpile stewardship mission highlights the roles of computer simulations and exascale computing.
LLNL ATDM addresses software infrastructure needs for multiple communities
The Advanced Technology Development and Mitigation program within the Exascale Computing Project shows that the best way to support the mission is through open collaboration and a sustainable software infrastructure.
