Re: the slides for my talk @ FOSDEM
Hi Sebastian, thanks for your feedback on the slides. As a matter of fact I'm aware of the pegasus matrix-based optimization as of the shimmy technique by Jimmy Lin. I thought that this kind of technique is general enough for all iterative graph algorithms, not just PR, and mostly using the naive algorithm would just help me out explaining the presentation. Messaging the adjacent vertices from the Mapper by iterating over them and emitting (otherVertex, myPartialPR) maps easily to our messaging paradigm. I'll maybe make it more clear in the next presentation. Thanks! On Mon, Feb 6, 2012 at 2:54 PM, Sebastian Schelter wrote: > Hi Claudio, > > nice job with the slides!

Question: Is the official giraph logo? I was looking for one, that I want to include in an internal slide deck and could not find one. Thanks! André

Sure, I ll wait until the video is put on YouTube and put both.

Ok weird, i asked and she mentioned she hasn't received any. Good luck. On Monday, February 6, 2012, Jakob Homan wrote: >> Jakob, are you still planning to talk there?

Re: the slides for my talk @ FOSDEM
Hi Claudio, nice job with the slides! I have only one small point to criticize: When PageRank is implemented with MapReduce, it's not necessary to have the graph passed through in each iteration. Mahout for example uses power iterations where the adjacency matrix is multiplied by the pagerank vector and only that vector has to be sent over the network. Pegasus uses a similar approach. /s On 06.02.2012 12:24, Claudio Martella wrote: > Hello guys, > > for those interested, here are the "slides" for my talk at FOSDEM. > > http://prezi.com/9ake_klzwrga/apache-giraph-distributed-graph-processing-in-the-cloud/ > > The event was very nice, a tight community and a great interest in > Giraph.
