Thank you for your comment, it did confirm my suspicions.

You framed the problem correctly. I will probably invest a bit of time studying the framework anyway, to see if a rewrite is interesting, since we hit scaling limitations on our Agent scheduler framework. Our main computational load is the massive amount of agent reasoning ( think JbossRules) and inter-agent communication ( they need to sell and buy stuff to each other) so I am not sure if it is at all possible to break it down to small tasks, specially if this needs to happen across CPU's, the latency is going to kill us.

Thanks

But the power of Hadoop is breaking down big problems into small pieces and
spreading it across many (thousands) of machines, in effect creating a
massively parallel processing engine.

But in order to take advantage of that functionality you must write your
application to take advantage of it, using the Hadoop frameworks.

So if I understand  your dilemma correctly.  I do not think that Hadoop is
for you, unless you want to re-write your app to take advantage of it.  And
I suspect that if you have access to a traditional cluster, that will be a
better alternative for you.

Hope that this helps some.

Hello list

We will be getting access to a cluster soon, and I was wondering whether
this I should use Hadoop ?  Or am I better of with the usual batch
schedulers such as ProActive etc ? I am not a CS/CE person, and from reading
the website I can not get a sense of whether hadoop is for me.

A little background:
We have a  relatively large agent based simulation ( 20+ MB jar) that needs
to be swept across very large parameter spaces. Agents communicate only
within the simulation, so there is no interprocess communication. The
parameter vector is max 20 long , the simulation may take 5-10 minutes on a
normal desktop and it might return a few mb of raw data. We need 10k-100K
runs, more if possible.



Thanks for advice, even a short yes/no is welcome

Greetings
Igor
