Is this system-on-chip?

Unfortunately not. The information extraction aspect involves heavy duty math, where the more computational resources you can throw at the problem the better. We have a bunch of servers where all the cores on the CPUs are running at max 24 hours a day. At the moment, we're not using GPUs for our matrix math (the matrices tend to be very large). For our matrix math I am a fan of the fast ojAlgo math library http://ojalgo.org

Pure Java for matrix math? Seems like that would be something to avoid. Have you benchmarked it?

[mikebennett]

I used the bench marks from http://code.google.com/p/java-matrix-benchmark

Decision came down to speed is reasonable, library has some other math functions I need, and time taken to build.
