Dear Andre sir, Thank you for your reply. I have gone through the threads but I didn't got the exact solution for my problem.
I have run the protein-ligand system upto nvt.tpr mdrun execution steps in my laptop with Ubuntu. It is running comfortably but showing the output -nan. Therefore, I thought to run it on the bolden cluster in our institute in that it is showing the following error. Will use 108 particle-particle and 12 PME only ranks This is a guess, check the performance at the end of the log file Using 120 MPI threads Using 1 OpenMP thread per tMPI thread starting mdrun 'Protein in water' 50000 steps, 100.0 ps. ------------------------------------------------------- Program gmx, VERSION 5.0.4 Source code file: /share/apps/src/gromacs-5.0.4/src/gromacs/mdlib/pme.c, line: 7 54 Fatal error: 2 particles communicated to PME rank 4 are more than 2/3 times the cut-off out of the domain decomposition cell of their charge group in dimension x. This usually means that your system is not well equilibrated.
