[news.eclipse.technology.ohf] Re: STEM Should also Run as a web applicat

["Daniel Ford" <daford@xxxxxxxxxxxxxxx>]

Matt,
    for the kinds of simulations we've been working on, mostly disease 
spread in sub-global regions (e.g, North America, Asia, etc.) modelled at 
administration level 2, we haven't really run out of horsepower quite yet so 
going to a parrallel computing model might be a bit premature.  These types 
of models create graphs with on the order of 10000 nodes and simuliar 
magnitude labels. Such models tend to run well on a single laptop. However, 
for much bigger models representing finer detail (millions of nodes in the 
representational graph) it might be the only way to make them work.  I 
expect disease models wouldn't really need quite that level of detail, but 
if you were doing some kind of situational awareness application coupled 
with integrated simulations for decision support then we'd need the power.

Something to think about or investigate is how we could leverage the fact 
that all of STEM's modeling code is generated by EMF.  One can provide their 
own JET templates to the EMF code generator, so could we, for instance, 
fiddle with the JET templates so that they generate code that would work 
directly with something like Hadoop?
