Your choice of number of MPI ranks and amount of resources results in using 12 OpenMP threads per rank, which is most likely inefficient. The optimum is usually between 1 and 6 threads per rank.
然后在gmx mdrun 后面加上了 -ntomp 6,就会有这样的提示:
Environment variable OMP_NUM_THREADS (12) and the number of threads requested on the command line (6) have different values. Either omit one, or set them both to the same value.
