| The value NPAR = 10 specified in the INCAR file was overwritten, |
| because it was not compatible with the 64 processes available: |
| NPAR = 64 |
| was used instead, please check that this makes sense for your |
| machine. |

| For optimal performance we recommend to set |
| NCORE = 2 up to number-of-cores-per-socket |
| NCORE specifies how many cores store one orbital (NPAR=cpu/NCORE). |
| This setting can greatly improve the performance of VASP for DFT. |
| The default, NCORE=1 might be grossly inefficient on modern |
| multi-core architectures or massively parallel machines. Do your |
| own testing! More info at https://www.vasp.at/wiki/index.php/NCORE |
| Unfortunately you need to use the default for GW and RPA |
| calculations (for HF NCORE is supported but not extensively tested |
| yet). |

| ----> ADVICE to this user running VASP <---- |
| |
| You have a (more or less) 'large supercell' and for larger cells it |
| might be more efficient to use real-space projection operators. |
| Therefore, try LREAL= Auto in the INCAR file. |
| Mind: For very accurate calculation, you might also keep the |
| reciprocal projection scheme (i.e. LREAL=.FALSE.). |

| The number of bands has been changed from the values supplied in |
| the INCAR file. This is a result of running the parallel version. |
| The orbitals not found in the WAVECAR file will be initialized with |
| random numbers, which is usually adequate. For correlated |
| calculations, however, you should redo the groundstate calculation. |
| I found NBANDS = 573. Now, NBANDS = 576. |
