I saw this poster at the conference and I was not impressed and in fact it was one of the weaker posters that I saw at the conference (it was light on details and had some of the information on the poster when talking about GPU's in general was not entirely accurate). It is really a poster that should not have been at SC at all. While it is interesting in the network sense the amount of data they can process is not anywhere close to the amount that is actually flowing through these large scale machines (up to 10 GB/sec per node) and there was no information about scaling this data collection (which would be needed at extreme scales) to obtain meaningful information to allow for tuning of network performance.
This poster should have been at a networking conference where the results would have been much more interesting to the crowd attending. Also of note, IIRC the author was using a traditional GPU programming model for computation that is not efficient for this style of computation. The speedup numbers would have been greatly improved by using a RPC style model of programming for the GPU (persistent kernel with tasking from pinned pages). However this is not something I totally fault the author for not using since it is a rather obscure programming technique for GPU's at this time.
