Hello,
My simulation ran till before it had to write the 2nd post.out file. Then It gave error: mpirun noticed that process rank 12 with PID 25320 on node exited on signal 9 (killed). I dont understand what process rank 12 is. What could be the reason for this error and how I can correct it? Thanks Nitisha |

Hi,
Process rank 12 is one of the cpu processors (you must have 12+ of them). Looks like it crashed during post-processing. How many cells do you have and how many cores are you using? Can you try to use less or more cores to see whether this crash repeat? |

I have 32 CPUs,
I run my mpirun command with mpirun -n32 No of cores per socket are 8. There are 2 sockets Is it possible that writing output file interval can effect the simulation, as when I changed my writing interval from 2 degree to 10 degrees, then the simulation crashed. |

Hello, I tried the simulation with less no of CPUs. I used mpirun np-10 as a command. Still I get the same error. And now it happens write at the start of the simulation.
When I run the box spray simulation rather than Engine simulation. I dont get such error till now. Thanks Nitisha |

Hi, Nitisha,
For your simulation how about email us off-line and we have some one to help you diagnose what the problem is. Thanks. |
