Here post your question :
The error occured when I had a npt.mdp run. What I can do under this situation?
gmx mdrun -v -deffnm npt
Compiled SIMD: AVX2_256, but for this host/run AVX_512 might be better (see
Reading file npt.tpr, VERSION 2021.5 (single precision)
NOTE: Parallelization is limited by the small number of atoms,
only starting 12 thread-MPI ranks.
You can use the -nt and/or -ntmpi option to optimize the number of threads.
Changing nstlist from 15 to 100, rlist from 2 to 2
Using 12 MPI threads
Using 2 OpenMP threads per tMPI thread
