Hi everyone, I have submitted pbs files to run GROMACS on a high performance computing cluster, but I received error files showing these messages:
"... librdmacm: Warning: couldn\'t read ABI version. librdmacm: Warning: assuming: 4 librdmacm: Fatal: unable to open /dev/infiniband/rdma_cm librdmacm: Fatal: unable to open /dev/infiniband/rdma_cm ..." and "-------------------------------------------------------------------------- mpirun noticed that process rank 28 with PID 0 on node shadow- 0119.hpc.msstate.edu exited on signal 11 (Segmentation fault). -------------------------------------------------------------------------- 40 total processes killed (some possibly by mpirun during cleanup)" This error happened when I used mpirun to run my jobs on several nodes (10 nodes in this case). When I didn't use mpirun and run with only 1 node, there is no error produced. The command I used are: *"gmx grompp -f step7_production_01.mdp -c step6.6_equilibration.gro -n index.ndx -p topol.top -o step7_1_01.tpr -maxwarn -1* *mpirun -np 200 gmx_mpi mdrun -v -deffnm step7_1_01"* Is that mpirun command correct? I'm not sure if those errors is relevant to using mpirun. I don't understand what the errors mean, or how should I fix them? Please help me with this problem. Thank you very much for sharing your time.
