…ed member variables (nspin, nrxx, npw, gg, tpiba, tpiba2, gcar) to local const variables before OpenMP parallel regions to eliminate ThreadSanitizer false positive warnings.
…arrier directive must be inside an explicit #pragma omp parallel region, not after #pragma omp for which ends the implicit parallel region. This fixes undefined behavior when compiled with OpenMP enabled.
…o distinguish from member variables (nst -> nst_, nz -> nz_, etc.)
…distinguish from member variables (nrxx -> nrxx_, npw -> npw_, nxyz -> nxyz_, nst -> nst_, nz -> nz_, nx -> nx_, ny -> ny_, nplane -> nplane_, ig2isz -> ig2isz_)
…nguish from member variables (npy -> npy_, nx -> nx_, lixy -> lixy_, rixy -> rixy_, nplane -> nplane_, and FFTW plan objects)
…. The #pragma omp for directive already performs implicit synchronization at the end of the loop, making explicit barrier redundant.
