@srowen I can guess at the history. `netlib-java` used to require that
users compile their own natives but, inspired by JBLAS, about 2 years ago I did
a big spike and beat Maven into submission to cross-build for all major
platforms (and some small ones too, like the Raspberry Pi) making it super-easy
for end users. At that point, I sort of feel that JBLAS has reached the end of
its shelf life but I don't know what other features it offers. The release
process for netlib-java is still a nightmare, thanks to OS X, but that doesn't
affect you at all... it is my cross to bare.
I've done a **lot** of work benchmarking different BLAS/LAPACK routines
(and Intel provide me with a gratis license, bless their souls, to aid with
this) as well as other mathematics routines. I **strongly** recommend you watch
my ScalaX talk to get a feel for what is behind this.
I would also like to use the same maven build process to make more
natively-enhanced mathematics routines available on the JVM (with a Java
fallback, always), such as the random number generators that we use extensively
in the financial services / investment sector. That's typically the bottleneck
in option pricing (i.e. Black-Scholes) for example.
