#5 OpenMOSIX over the Internet
I have two clusters running together on opposite coasts
tied to the Internet via dedicated T1s. Both work fine,
and are using 2.4.19 kernels openmosix7. All kernels
on all nodes are compiled using the same openmosix
kernel options.
The two clusters are tied together via an ipsec gateway.
There is no firewalling between the two clusters. . .just a
mandatory rsa pipe :)
I'm trying to join the two clusters together, and am
having minimal success. Tcpdump shows me lots of
UDP traffic between nodes when I do a mosctl isup
<node on the other cluster> all the mosix.map files are
correct. . .but the nodes just won't see eachother.
Is there perhapse a network connection speed threshold
built into openmosix? i.e. it won't work across the
Internet? I know performance would be terrible across
those T1s but the coolness factor of migrating a process
2500 miles is simply irresistable.
So the Question: Does openmosix have minimum
network speed requirements?

openMosix needs low latency to work best. There are a lot of timeouts built into openMosix to prevent slow latency to create the split personality problem inherent to clusters.
