Run a shared memory parallel version on a network?
If you are familiar with the parallel version of Fluent, please give me some help.
I have four multi-processors machines(all win2k) which constitute a network.I am solving a CFD problem with fluent 5.5 now and this computation need huge memory which exceeds the size of a single machine, so I want to perform a parallel version with shared memory on this four-machine network. Thus each machine can hold a part of the whole data and case file in its local memory and memorys on four machines can be used as one on a single machine.I have tried "Socket", but it doesn't share memorys on other machines. So I am eager to get some help from you if you know how to do it. Thank you very much.
Re: Run a shared memory parallel version on a netw
you should start fluent with the option -pnet. But as far as I remember it means the same like socket in the GUI-run-menue.
Did you spawn processes to other hosts?
So let me describe how to start a parallel session from the beginning to give you the opportunity to compare it with your way:
1. start fluent with fluent 3d -t2 -pnet
(t2 stands for 2 processes on the first host. If you have more cpus increase the value)
2.In the GUI open the /Network/configure panel and spawn processes to the other hosts (machines)
or with the TUI:/par/netw/sn
then provide the machine name
repeat it with every cpu-node
3. read in your case and data.
