Hi,
I've recently been exploring the distributed networking options of OpenFOAM and I have three questions: 1. does anyone have a firewall setup that works with openMPI stuff? I'm hesitant to shut the firewall off, but I don't know the steps to setting it up correctly (using OpenSUSE 10.3). 2. What sort of speed-up has anyone seen with bproc stuff? any? is it worth it? 3. The manual seems a little scant on how to set up the cases for distributed vs. non. if I have 2 dual-core processors on 2 computers, how many root directories do I specify, or, if they're the same, is this even needed? Also, what is the speed-up, if any, of choosing distributed computing? With regards to 3, I'd be happy to test this on my own, but when I set distributed yes, roots 2 ( /home/mjaworsk/..../interFOAM /home/....same....) interFOAM yelled at me with improper syntax on those lines. what does it really want there? when I set it to "no", it ran fine across both computers. Thanks for any help on these, Mike |

3. per process in your parallel run you'll have to specify a directory. So e.g. mpirun -np 4 means you need 4 roots. Even if all processes are on the same processor or core or whatever.

Hi Mattijs,
Thanks for the note. I added all four lines and I had been missing some quotation marks. It's running now. Thank you much. -Mike |
