getOnTheFlyPlan...48 x 32 x 32 lines in vasp_gpu out files

#1 Post by scanmat_centre » Tue Nov 14, 2023 12:31 pm

I recently compiled vasp_gpu on our Tesla P100-SXM2-16GB Device. The installation was done well without any errors. I have used CUDA 12.3 for the vasp_gpu installation. I have done some test calculations and found that between each electronic minimisation step, there are unknown terms like "getOnTheFlyPlan...48 x 32 x 32". I don't know why these lines appear; because of these lines, my slurm-***.out files taking so much storage space to write. I have counted the number of lines in between the first two electronic steps. There were 35911 lines were there. I have given an example slurm-out file below. Any other information needed I will give. Please Help me with this issue.

| ----> ADVICE to this user running VASP <---- |

| You have a (more or less) 'small supercell' and for smaller cells |
| it is recommended to use the reciprocal-space projection scheme! |
| The real-space optimization is not efficient for small cells and it |
| is also less accurate ... |
| Therefore, set LREAL=.FALSE. in the INCAR file. |

This error occurs on the CUDA-C GPU port of VASP:

Note however that this version is deprecated and instead, we recommend that you use the OpenACC GPU port of VASP:
