I think there are two questions here:
1. Running MPI applications on "slow" networks (e.g., 100mbps). This is
very much application-dependent. If your MPI app doesn't communication with
other processes much, then it probably won't matter. If you have
latency/bandwidth-sensitive applications, the
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 is
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
