Is it possible to use a daisy chain network for MPI Ansys FLUENT in Windows 10?
I have three dual port 10Gb intel X540 in three computers
Looking for a way to manage MPI on three computers without need to use a high speed switch to reduce the network latency and costs
If thats possible for MPI, would you please let me know the network setup, this doesn't work
Port 1: 192.168.1.1.2
Port 2: 192.168.1.3
GW 192.168 .1.1
Port 1: 192.168.1.4
Port 2 192.168.1.5
Port 1 192.168.1.6
Port 2 192.168.1.7
Topology:Port 1 of Sys 1 >> Port 1 of Sys 2
Port 2 of Sys 2 >> port 1 of Sys 3
Port 2 Sys 3 >>Port 2 Sys 1
I wonder if you could help me in these questions

first of all, MPI needs Active Directory authentication, hope that is available. If AD is not available, then please stop and have that configured first.
Ideally use a switch. I would check if there is a low cost high performance 4 port option.
the daisy chain - this question is really about network setup. I have not tried such a setup. PErhaps someone who has tried such a setup can chime in
as for MPI and processes - On one hand I think it could work if the network is configured correctly. (Each host would be needed to resolve to the right IP for the other.)
On other hand I am worried that the master processes might bind to one interface and listen on that interface. If bonded interfaces on master node and different IPs on slave nodes, then not sure if it will work.
Best to test with generic MPI tests first and not with an application.
