Its doable, the scaling will not as good, because a network is a
network. If you are using just regular 100Mbit, you will not scale
as far as really good 1gig ethernet, but we are still talking about
tcp which incurs a penalty over networks like infiniband and myrinet.
Tcp is the largest issue, its going to be really application
dependent you are right.
On another note though many of the older cluster that are now out of
service used just 100Mbit ethernet and worked.

Hi,
Is MPI paradigm applicable to the cluster of regular networked
machines.
That is, does the cost of network IO offset benefits of
parallelization?
My guess is that this really depends on the application itself,
however,
I'm wondering if you guys know of any success stories which involve
MPI
running on a set of networked machines (not beowulf cluster or any
SC).
Thanks,
