BLAS alternatives

[mschonwe]

Is is possible to use an alternative to ATLAS?

Running the install for ATLAS I hit the "CPU Throttling apparently enabled!" error/abort. I'm reluctant to disable CPU dynamic frequency scaling, especially when I have a number of other linear algebra libraries already installed (cuda/cublas, Openblas, boost/ublas, scipy/blas). Wouldn't the cuda libcublas be acceptable, or even preferable?

Both ATLAS and libcublas are required, for CPU and GPU computation respectively.

[mschonwe]

If configured for GPU (./configure --use-cuda=yes...) are there still CPU based operations that require BLAS?

[fmetze]

Decoding and pre-processing, I think, is based on CPU computation. You can also use MLK, OPENBLAS instead of ATLAS.

Thank you very much! I was able to configure and make successfully after specifying OPENBLAS.
(./configure --use-cuda=yes --cudatk-dir=/usr/local/cuda --mathlib=OPENBLAS --openblas-root=/usr/local)
