Many-Fermion Dynamics—nuclear, or MFDn, is a configuration interaction (CI) code for nuclear structure calculations. It is a platform-independent Fortran 90 code using a hybrid MPI+X programming model. For CPU platforms the application has a robust and optimized OpenMP implementation for shared memory parallelism. As part of the NESAP application readiness program for NERSC’s latest Perlmutter system, MFDn has been updated to take advantage of accelerators. The current mainline GPU port is…

The computational strategies employed in a state-of-the-art CI code MFDn (Many Fermion Dynamics - nuclear) as well as techniques recently developed to enhance the computational efficiency of M FDn are described.
High Performance Optimizations for Nuclear Physics Code MFDn on KNL
Initial optimization strategies and results on MFDn, a large-scale nuclear physics application code, running on a single KNL node are presented and a vectorized version of a popcount operation is described to avoid serialization on intrinsic popcnt which only operates on scalar registers.
No Core CI calculations for light nuclei with chiral 2- and 3-body forces
The atomic nucleus is a self-bound system of strongly interacting nucleons. In No-Core Configuration Interaction calculations, the nuclear wavefunction is expanded in Slater determinants of

ab initio nuclear structure calculations of p-shell nuclei with JISP16
We review energies and magnetic moments of p-shell nuclei obtained with the ab initio No-Core Full Configuration (NCFC) approach using the JISP16 realistic nucleon–nucleon interaction. We present
Few- and many-nucleon systems with semilocal coordinate-space regularized chiral two- and three-body forces
We present a complete calculation of nucleon-deuteron scattering as well as ground and low-lying excited states of light nuclei in the mass range A=3-16 up through next-to-next-to-leading order in
Emergence of rotational bands in ab initio no-core configuration interaction calculations
Rotational bands have been observed to emerge in ab initio no-core configuration interaction (NCCI) calculations for p-shell nuclei, as evidenced by rotational patterns for excitation energies,
