FLUENT 6.3.26 Parallel Job

Hy every one I'm using FLUENT 6.3.26 on parallel computations and one interesting thing is happening.
When I load it on a CPU dual core I can see that one of the CPU is full and the other is empty. The same happens when I load it on two different CPUs. On the Windows Task Manager I can see a process called fl_mpi6326.exe with 50% of CPU (dual core). As you can see I'm using the MPICH2 as the MPI. Does some one know what is happening? And Why it is happening?? Best regards Lourival |

Set up your hosts file correctly.

If you have 2 computers and first one has 2 cores. The host file should be
computer1 computer1 computer2 Then, fluent will run on computer1 with 2 cores. : ) nantaratn@yahoo.com |

The host file is set up OK: computer1 computer1 computer2
Maybe I wasn't clear, the process fl_mpi6326.exe is running with no Calculus. I only read the case and file and the process is already running. Hugs Lourival |

if you use fluent journal, in the end of your journal should have a command to exit FLUENT. Then, the fl_mpi6326.exe will closed automatically.
(ti-menu-load-string (format #f "exit " )) cheers, Nant. |

Dear Nant,
Thanks for your advanced advice. Let me describe in some more details what is happening: When I run on CMD the following command: fluent 3d There is a processes whit a image name fl6326s.exe whit no CPU usage Probably this is the SERIAL solver. A different thing happens when I run: fluent 3d -t2 There is four new process: fl_mpi6326.exe fl_mpi6326.exe fl6326.exe cx373.exe Probably the fl_mpi6326.exe is the processes that is running on each CPU and the fl6326.exe is the HOST. I don't guess what is the meaning of cx373.exe, but this is not the question. The question here is: Why one of the fl_mpi6326.exe is running full? CPU = 50. Note that I didn't load any case. I just run the command, fluent 3d -t2, on the CMD. Best regards Lourival |

hi i have just started using parallel processing. i thought that that is during only start up procedure. during iterate you will not find this problem. that is one thing and another that have u tried with load balancing?.
