Hello César,

It seems like you are running heavy simulation. I have noticed one thing that you are doing pretty well with intel MPI or

as a suggestion use MPICH or MPICH2 then see the difference. You can try this on Linux as well and see if there is any change.

Thanks,
Martin

Oh, right! It would be good to try these 2 options out, but I may have to do it via command line since in the GUI launcher of Fluent 14 are not available, at least in the version I'm running. I'd like to try this in Linux but now it's urgent to obtain results for my thesis. Maybe later when I have more free time.

Regards

Hi Martin,

Hope you are doing well. I'm facing a problem now trying to add another CPU to the ones I told you before in the past thread. This new machine has Windows XP - 64bit as OS. As I told you I have 3 machines with Windows 7 running Fluent in parallel. The MPI for these 3 machines is Intel. I followed the steps to set the MPICH2 as you suggested in the next quoted message:

go to command line and install smpd service by typing

smpd -install

you have to install this service in all your nodes and there is also a file of cluster manager where you can see all your nodes and head node are online highlighted by green line.
But I couln't make it work. I made sure that every machine can see the other ones in the network. There is no problem in copying and moving files between them, too. When I try to run Fluent using this new machine as a new node with Windows XP, it hangs printing a message that reads something about a port 8677 and that the connection could not be done. I assume that this is due the XP OS of the new CPU but I think that this should not be a big deal since all are 64-bit operating systems.

Now I'm back again with the 3 machines I had before while I fix this problem. Please, give me an advice. I'm sure this can be solved.

Thanks in advance,
César
