As you know, graph is a very useful data model. Matrix is the great
tool to store graph data and process them. Therefore, I think that
they will give many benefits each other. I agree with your opinion.

If we do so, how can we integrate them? What do you think about that?

Hello Mr. Yoon,

I was delighted to hear of your proposed Hamburg project. I am a new
user of Hadoop (and Hbase). It looks like that I will be spending a
substantial amount of time working in this environment over the next
couple years, for both DOE bioinformatics work (my primary field) and
for work funded by DoD. I am enthusiastic about using Hadoop, Hive,
Hbase. Also am quite interested in the Mahout project.

While I cannot offer advice as to where to place your new project within
the Apache framework, I did want to offer my support. I believe that it
could well be of value in the coming years both to me, for my
bioinformatics research, and to other researchers here at PNNL working
in the areas of social networks (in our national security directorate)
and in a set of projects directed toward making the electrical grid
"smarter". I would not be able to contribute any code until I found
funding from current or new projects for my time. But if Hamburg moves
forward and can demonstrate its usefulness, that might be a real

And in regards to funding for getting you some help: if you can find a
collaborator based at a university or non-profit, said collaborator
could well apply for a grant from the US National Science Foundation for
open source Hadoop-based development of graph computing / mining
algorithms. The NSF Computer and Information Science and Engineering
Directorate is awarding grants specifically devoted to the area of graph
mining (at least this year - hopefully will continue next year - anyway,
NSF gives money for algorithm and tool development in general - friendly
to that). I can't apply (at least not directly) - NSF does not like to
give money to other US government labs. But I would think you could find
someone in academia - perhaps someone already working with the Mahout
group. It would appear a natural fit. I presume there are a number of
people associated with the Apache org who know something about the NSF
and could offer further advice in that direction.

I look forward to hearing more about Hamburg, as it progresses.

Subject: Discussion about Hamburg (provisional name) open sourcing

Hello communities,

I'm the one of the Hamburg (provisional name), which is the graph
computing framework on Hadoop sponsor. Now we're working on the
perfection of our prototype project, and we'll propose the Hamburg
project soon.

- http://wiki.apache.org/hadoop/Hamburg, a wiki page
- http://throb.googlecode.com/, a prototype project

BTW, before we decide to propose, we need time just to consider where it
belongs to.

Since it aims to create a "general graph computing framework" on Hadoop,
I'd like to propose it as a sub-project of Hadoop. On the other hand,
since the matrix and graph are both in the domain of scientific
computing and BSP model could be used for matrix computation areas, I
think this project also can be integrated with the Hama project.

WDYT? Any advices are welcome.

Best Regards, Edward J. Yoon @ NHN, corp.
