Subject Re: Turn BLAS on MacOSX
Date Sun, 11 May 2014 16:32:08 GMT
Hi Debasish,

In https://github.com/apache/spark/blob/master/docs/mllib-guide.mdDependencies
section, the document talks about the native blas dependencies
issue.

For netlib which breeze uses internally, if the native library isn't found,
the jblas implementation will be used.

Here is more detail about how to install native library in different
platform.
https://github.com/fommil/netlib-java/blob/master/README.md#machine-optimised-system-libraries


Sincerely,

DB Tsai
