Hi all:
I wrote an e-mail many days ago about continuing run in Gromacs-4.0 with check point file. But I can't solve this problem yet. I run a simulation with mpiexec -machinefile ./mf_24 -np 24 mdrun -v -append -cpt 5 -cpi dppc_md_prev.cpt -cpo dppc_md.cpt -s dppc_md.tpr -o dppc_md.trr -c dppc_md.gro -g dppc_md.log -e dppc_md.edr in 4 nodes. But when I continue to run the simulation with mpiexec -machinefile ./mf_24 -np 24 mdrun -v -append -cpt 5 -cpi dppc_md.cpt -cpo dppc_md_2.cpt -s dppc_md.tpr -o dppc_md.trr -c dppc_md.gro -g dppc_md.log -e dppc_md.edr or with mpiexec -machinefile ./mf_24 -np 24 mdrun -v -append -cpt 5 -cpi dppc_md_prev.cpt -cpo dppc_md_2.cpt -s dppc_md.tpr -o dppc_md.trr -c dppc_md.gro -g dppc_md.log -e dppc_md.edr because there're 2 check point file in the simulation directory, I tried both of them. I always get following errors: Reading checkpoint file dppc_md_prev.cpt generated: Fri Mar 20 08:53:47 2009 or Reading checkpoint file dppc_md.cpt generated: Fri Mar 20 08:58:08 2009 Loaded with Money Fatal error in MPI_Bcast: Message truncated, error stack: MPI_Bcast(1145)...................: MPI_Bcast(buf=0x7fffc33242dc, count=4, MPI_BYTE, root=0, MPI_COMM_WORLD) failed MPIR_Bcast(229)...................: MPIDI_CH3U_Receive_data_found(254): Message from rank 0 and tag 2 truncated; 12 bytes received but buffer size is 4 Fatal error in MPI_Bcast: Message truncated, error stack: MPI_Bcast(1145)...................: MPI_Bcast(buf=0x7fff6c0da09c, count=4, MPI_BYTE, root=0, MPI_COMM_WORLD) failed MPIR_Bcast(229)...................: MPIDI_CH3U_Receive_data_found(254): Message from rank 4 and tag 2 truncated; 12 bytes received but buffer size is 4 Fatal error in MPI_Bcast: Message truncated, error stack: MPI_Bcast(1145)...................: MPI_Bcast(buf=0x7fff9ac2ebec, count=4, MPI_BYTE, root=0, MPI_COMM_WORLD) failed MPIR_Bcast(229)...................: MPIDI_CH3U_Receive_data_found(254): Message from rank 0 and tag 2 truncated; 12 bytes received but buffer size is 4 rank 16 in job 5 Node115_33001 caused collective abort of all ranks exit status of rank 16: killed by signal 9 rank 8 in job 5 Node115_33001 caused collective abort of all ranks exit status of rank 8: killed by signal 9 rank 6 in job 5 Node115_33001 caused collective abort of all ranks exit status of rank 6: killed by signal 9 Can someone help me with this problem? Appreciate any help in advance! Best wishes! 2009-03-20 xuji
