Luc Maisonobe resolved MATH-270.
--------------------------------
Resolution: Won't Fix
Since MATH-269 will not be fixed, this issue which depends on it cannot be
fixed either.
> Wrapper layer for F2J translations of BLAS/LAPACK
> -------------------------------------------------
>
> Key: MATH-270
> URL: https://issues.apache.org/jira/browse/MATH-270
> Project: Commons Math
> Issue Type: New Feature
> Affects Versions: 2.1
> Reporter: Sam Halliday
>
> This is part of the proposal to integrate MTJ, netlib-java and commons-math
> which has been well received on the developers' list, @see
> http://www.nabble.com/commons-math,-matrix-toolkits-java-and-consolidation-tt23537813.html
> This depends on issue MATH-269.
> Netlib-java provides a wrapper layer around Java implementations of BLAS and
> LAPACK, the industry standard APIs for linear algebra calculation. This
> functionality would be of great benefit to commons-math both internally and
> as part of the public API.
> A major advantage of using netlib-java rather than direct access to Java
> translations of BLAS/LAPACK is that natively optimised implementations can be
> configured at runtime. For most normal desktop machines, the performance
> difference is negligible (hey, Java is seriously fast these days!), but for
> machines with custom hardware and BLAS/LAPACK implementations (e.g. GPU,
> FPGA, otherwise parallel) the performance difference can be orders of
> magnitude.
> The idea would be that commons-math would define an API and use it internally
> for linear algebra calculations. The decision to make this part of the public
> API can be decided afterward.
> The author of netlib-java (i.e. me!) is more than happy to release this code
> under an Apache licence, however the APIs are copyright the authors of
> BLAS/LAPACK and therefore BSD licenced (which I understand is compatible).
