http://people.apache.org/~edwardyoon/site/ - Please review and feedback
here.

Re: Website Update
Posted by "Edward J. Yoon" <ed...@apache.org>.
I found another bug in Graph package and SemiClustering example.
If setup() method should be called once at the start of the program,
below variables should be declared as a static (purly class
variables). Otherwise, it won't work with DiskVerticesInfo or
Serialization version.
{code}
private int semiClusterMaximumVertexCount;
private int graphJobMessageSentCount;
private int graphJobVertexMaxClusterCount;
@Override
public void setup(HamaConfiguration conf) {
semiClusterMaximumVertexCount =
conf.getInt("semicluster.max.vertex.count", 10);
graphJobMessageSentCount =
conf.getInt("semicluster.max.message.sent.count", 10);
graphJobVertexMaxClusterCount = conf.getInt("vertex.max.cluster.count", 10);
}
{code}

Almost fixed.

2. HAMA-821
Graph examples still has memory issue.

As described in there, 6M poinsts input and Oracle BDA was used. Hama
finishes KMeans in a few seconds. Mahout takes almost 500 ~ 1000 secs.
See also http://lambda.uta.edu/mrql-bsp.pdf.
Do you need more?

Input was too small :/ So, I'll update website using confident benchmarks soon.
https://twitter.com/tjungblut/status/414717432293363712
After I saw this tweet, I thought we need to update the website. Many
people seems think that hama is a graph processing framework. If you
have some good idea, Please let me know.
P.S., I recently tested Hama examples and 80% of them didn't work.
Let's fix them all in 0.7 release and update the website clearly.

Hi all,
I just noticed that the graph on our homepage [0] looks very similar to the
one on Spark homepage [1] so I wonder if we could at least make it a bit
clearer either by writing the benchmarks results in a table near it (it
seems Hama always takes ~0) or something else I cannot think to right now.
The reference to the benchmarks wiki page is ok but I cannot find the entry
for the comparison with Mahout, maybe I'm missing something ...
Regards and happy new year everyone.

Hi,
It looks nice. Is it possible to add more description to the figure? When
people first saw this, they may not know what the x axis is (the number of
cores or the number of the number of groom servers?). Moreover, it is
better to tell the reader some specs of the dataset used.

Re: Website Update

Hi Edward,
I think it generally looks better than the current one, I would just change
this:
Many data analysis techniques such as machine learning and graph algorithms
require iterative computations but MapReduce model doesn't fit for these
iterative data analysis applications. To run these iterative data analysis
applications more efficiently, Hama offers pure Bulk Synchronous Parallel
computing engine.
to something like this:
Many data analysis techniques such as machine learning and graph algorithms
require iterative computations, this is where Bulk Synchronous Parallel
model can be more effective than "plain" MapReduce. Therefore to run such
iterative data analysis applications more efficiently, Hama offers pure
Bulk Synchronous Parallel computing engine.
As I wouldn't say MR is inherently not good for iterative computations,
just BSP can be a better / more perfomant alternative.
My 2 cents,
Tommaso
