FYI, I've added instructions to Netlib-java wiki, Sam added the link to them from the project's readme.md https://github.com/fommil/netlib-java/wiki/NVBLAS

Sparks; Sam Halliday; dev@spark.apache.org; Ulanov, Alexander; jfcanny Subject: Re: Using CUDA within Spark / boosting linear algebra Hi Alex, Since it is non-trivial to make nvblas work with netlib-java, it would be great if you can send the instructions to netlib-java as part of the README. Hopefully we don't need to modify netlib-java code to use nvblas.
