Terracotta Discussion Forums (LEGACY READ-ONLY ARCHIVE)

We have a highly parallel application that will be scaled to work in a clustered environment. We had planned on using JINI and JavaSpaces as our technology of choice for this development but having just discovered Terracotta I am investigating its possible application for this problem.

However, before I even get started I wanted to first ask you guys if Terracotta is suitable for parallelizing an application (my understanding is that it is)?

The parallel area of the application looks something like this:

for dataItems = 0 to 1,000,000
for itemFeature = 0 to 1000

sharedData3[itemFeature] += sharedData1[itemFeature] * sharedData2[dataItems][itemFeature]

end
end

So calculations and updates of shared data within nested loops, nothing fancy but inherantly parallel.

If Terracotta can help me scale this in a clustered environment without code changes that would make it worthwhile evaluating.

Thanks!

Ian,

Thank you for writing.

There is an excellent example of a highly parallel application on our blog that deals with calculations of a Mandelbrot fractal. I think you'll find it very interesting. Please refer to;

If you have any further questions during your evaluation, please feel free to write again.
