Dear all, I do not know whether I should ask this on openmpi forum or Amber forum but mpirun seems to crash randomly when they are subjected to long calculation. I have build openmpi from openmpi-1.6.2. I have used the following commands for configuring and installation: ./configure --prefix=/usr/lib64/mpi/gcc/openmpi --exec-prefix=/usr/lib64/mpi/gcc/openmpi make all install
Some calculations run completely fine but some of them crash randomly with the following type of error. -------------------------------------------------------------------------- mpirun noticed that process rank 3 with PID 5028 on node drsikandarserver exited on signal 1 (Hangup). -------------------------------------------------------------------------- I am using nohup before the mpirun command. The general structure of the command is nohup mpirun -np 8 sander.MPI .... RegardsSaad Raza
