Subject Re: [VOTE] Apache Mahout 0.13.0 Release Candidate

Built and tested source distribution with both profiles -Pviennacl and -Pviennacl-omp.

Ran SparseSparseDrmTimer.mscala through the shell in both pseudo cluster and local[2] mode

Tested with several iterations and combinations of arguments eg:


Mostly with out issue in a consumer grade card.

Note: in the shell after the %*% is called by a partition and the GPU is in use, will get
a native failure exception which is caught and allows for MMul of that partition to fall back
to JVM MMul (single-threaded).. this should be changed in 0.13.1 to fall back to OpenMP MMul.

Note: Binary distribution is built for Tesla GPUs. My card was not compatible, though out
target is higher end GPUs on AWS or PowerPC (PowerPC uses  teslas) so not a blocker IMO.

We will target a wider range of cards in the next distributions.

Hashes and sigs confirmed, bin and src (viennacl and viennacl-omp)
artifacts run the spark shell and the sparse drm test fine, and kick off
the GPU.
