Problem running with 3 CPU's in parallel
Hello everyone,
I have setup clustring environment on ubuntu 12. on 3 machines. 1 server and 2 clients my cluster setup works well with any 1 server and 1 client combination, but i was unable to run on all 3 machines for buoyantSimpleFoam in parallel i m using command mpirun -hostfile machines -np 3 /nfs/openfoam211/bin/foamExec buoyantSimpleFoam -parallel when i execute this command for 3 machines than i din get any response not even an error it just hangs, i check process on other 2 clients machines using Top command, so i can see that server is trying to initiate some process from server IP but it goes off every while and than, and ultimately buyantSimpleFoam is not running, but it works perfectly with and 2 machines with 1 server and 1 client with different number of cores whatever i assigned. (i personally feel its interprocess communication problem between clients) Please Help me, any solution for above, its really very Urgent, Thank u so much. |

Thanks for your help but still not solved, any other ways
I tried with this command as below but still same problem persist,
mpirun --mca btl_tcp_if_exclude lo,virbr0 -hostfile machines -np 6 /nfs/openfoam211/bin/foamExec buoyantSimpleFoam -parallel is there any need to have passwordless SSH between 2 client machines as well? or any other solution Also my Test-parallel is not working for 1 server and 2 clients and it hangs after giving execution command, but works perfectly fine when i assigned with 1 server and 1 client. can you please help me out to identify and resolve the problem. |

For Skype or phone, it'll have to be on-duty and you'll have to be willing to pay for the support; you can either send me an email or contact the company I work for, namely blueCAPE: http://www.bluecape.com.pt |
