Hi everybody,
I need to submit a star-ccm job to a cluster, but I do not know how to do that. The job should be submitted to slurm.

Sorry, never dealt with slurm.
Have you tried contacting cd-adapco? Generally they have been very responsive to questions like this for me. |

Thank you rwryne, I think the issue is mainly related to writing the commands in LINUX.

Hi,
I run my thesis in a linux cluster. Maybe this can help you: /opt/CD-adapco/StarCCM7.06.012/star/bin/starccm+ -rsh ssh – server –on 195.251.126.227:3,195.251.126.225:3 /media/shared/sims/pipe_porous.sim The above is the commands in the linux. I connect via ssh protocol. Also all the clusters must look on the same file, I'm using samba for that. I hope it helped.. Yours, rick |

Thank you rick,
I wrote the following batch file. what do you think is the problem? #!/bin/sh ### ### Job name #SBATCH --job-name=threephase ### Name of queue to submit to #SBATCH --time=40:00 ### Number of nodes required for the job #SBATCH --nodes=2 ### Number of processor cores #SBATCH -n 8 ### Amount of memory per core #SBATCH --mem-per-cpu=12000 ### The actual job execution cd /user/siara817/cfdfiles/threephasestest /pack/STAR-CCM+/starccm+5.02.010 -nodisplay -r threephasestest Thank you again Siamak |

What happens, if you use your command? Does it work at all? I am not sure about option '-r' but have never used it.
What I would use is option -np 8 for use of eight processors |

Thanks Oliver,
It gives a Job ID but when I check the job, there is no information, i.e. there is a fail. Exactly, I have doubt about the last part. my cfd file is in user/siara817/cfdfiles/ and the cfd software is located in /pack/STAR-CCM+/starccm+5.02.010 I do know if it is the correct way of asking the SLURM to call STAR-CCM to run the file. |

Hm,
in my opinion your last line should look like /pack/STAR-CCM+/starccm+5.02.010/star/bin/starccm+ -np 8 -batch threephasestest to start a running server on 8 procs. Probably you could add a " > output.log" to the line to have the output of CCM+ directly written to your folder. In this file you could also see the id of your CCM+ server process. BTW, ccm+5.02 is from April 2010, current version is 8.04 |
