Validated against QE

Total energies agree with Quantum ESPRESSO to 0.07 meV/atom on Si LDA Γ-only and 0.15 meV/atom on Si 4×4×4 shifted. Forces match to 5 significant figures via finite differences.

GPU-accelerated

Pluggable backends for CUDA (NVIDIA), HIP (AMD), and Metal (Apple Silicon, fp32 research tier). Physics code stays vendor-agnostic; adding a backend touches only one folder.

MPI-parallel & PAW-ready

k-point and band parallelism via MPI. PAW pseudopotentials, hybrid functionals (PBE0, HSE06), spin-polarized LSDA, and variable-cell relaxation — all in a single binary.
