[openib-general] IPoIB Question

[Sean Hubbell]

We currently have a non-homogeneous cluster so that seems that would 
possible explain a few of the differences that I have seen on some of my 
tests. I will look at netperf.org and see what they have to offer.

  On another note, is there plans to have IPoIB support the full 
throughput that infiniband 4x or 12x has? Specifically, can I keep my 
legacy apps and just upgrade the network to take advantage of the bandwidth?
