void DNDS::OMP::set_full_parallel_OMP ( )

inline

Configure OpenMP and Eigen threading for the "distributed OMP" pattern.

Sets the OpenMP thread count from the DNDS_DIST_OMP_NUM_THREADS environment variable (falling back to 1) and disables Eigen's internal parallelism so it does not oversubscribe the MPI+OpenMP layout.

Intended to be called once near main() when DNDS_USE_OMP is on.
