Hi everyone,
I just wondered, if it is possible to use all the cores of my computer, so that the simulation would proceed faster. If it is possible, could somebody tell me, if I can adjust these new settings directly in AVL or do I have to do this with the Windows-Settings-window Best regards kingoreo |

Hi,
How many cores do you have? And you need to describe FIRE version and OS information. Normally, MPI should speed up the calculation. And HP-MPI library will be installed during FIRE installation. When you click the "start calculation", "Job Setup" window will be popped up. You can select "MPI" as simulation mode and define # of CPUs. Very straightforward... Just try. |

I don't know how many cores do you have in your system.
It depends on number of CPU cores. |

In general, the use of detail chemistry results in long calculation time.
You can use all of cores for calculation. And if you are using v2013, the option "clustering" or "multi-zone" for general gas phase reaction can be applied to reduce the calculation time. |

Hi kimmhw
when i use more than one CPUs in job setup I face this error: mpirun: gethostbyname(amin) failed mpirun: Line 1: Invalid hostname: amin I don't know what I enter in the HOST name... what should I do? thnx amin_u50 |
