Hi, everyone, I was using Gromacs-4.0.3 to run my MD calculations parallell on our High performance clusters for a large system which was crashed because I run out the time limits. So I tried to resume my calculations by the script as follows:
#PBS -N gromacs #PBS -l walltime=250:00:00 #PBS -l nodes=8:ppn=2:quad #PBS -j oe echo Using nodes cat $PBS_NODEFILE module load mpich module load intel-f module load gromacs-4.0.3 cd $PBS_O_WORKDIR cd /home/yxp17/impd/impd1/wt_wo /usr/local/bin/mpiexec mdrun -multi 16 -s md.tpr -cpi state.cpt -append But it will stop and show the message as follows "Whatever Happened to Pong ?" (F. Black) Halting program mdrun gcq#180: "Whatever Happened to Pong ?" (F. Black) [0] MPI Abort by user Aborting program ! [0] Aborting program! p0_12952: p4_error: : -1 p4_error: latest msg from perror: No such file or directory ------------------------------------------------------- Program mdrun, VERSION 4.0.3 Source code file: gmxfio.c, line: 736 Can not open file: traj.trr ------------------------------------------------------- How can I solve the problem? Thanks a lot Yi
