ELPH_WF_CACHE_PREFILL = [logical]
Default: ELPH_WF_CACHE_PREFILL = .TRUE.
Description: Determines whether to pre-fill the wavefunction (WF) cache before starting the calculation.
| Mind: Available as of VASP 6.5.0 |
When enabled, the cache is populated in advance, avoiding one-sided MPI communication during the main computation loop. This can significantly improve performance and scalability, especially for large parallel runs.
