[Octave-bug-tracker] [bug #43246] On Mac, should use the Accelerate BLAS by default

[anonymous]

Follow-up Comment #2, bug #43246 (project octave):

Results of make check with Apple BLAS:

Summary:

  PASS     11535
  FAIL         2
  XFAIL        7
  SKIPPED     60

Results of make check with Octave's built-in BLAS (which appears to be
reference, not ATLAS):

Summary:

  PASS     11535
  FAIL         2
  XFAIL        7
  SKIPPED     60

The blas issues you mention appear to date from 2008.  More recent reports of
segfaults say that the same segfaults occur with Apple's BLAS and with Atlas.


Given that Apple's BLAS has been around for years and is *vastly* more widely
adopted than octave, I suspect segfaults in make check are more likely to
relate to bugs in octave than bugs in the BLAS.

As for benchmarking -- I've benchmarked them all outside of octave (MKL >
Apple BLAS > Open Blas > Atlas > Reference); I can't get octave to compile
consistently enough to benchmark here.

As I said in the other report comment, there are massive problems in the mac
distribution of octave right now.  

I'm trying to help you.

If you look at the tone of your responses to me, I think you may start to see
why these issues with octave haven't been fixed.
