On 32-bit Ubuntu 12.10. My Make.user file reads:

USE_MKL = 1
MKLLIB = /home/bjohnson/intel/mkl/lib/ia32

But, starting with a completely fresh clone of julia, make seems to bail out at the arpack tests. Here's the bottom of the build output:

Making check in UTIL
Making check in SRC
Making check in .
Making check in TESTS
/home/bjohnson/julia-mkl/deps/arpack-ng-3.1.3/TESTS/.libs/lt-dnsimp: error while loading shared libraries: libmkl_rt.so: cannot open shared object file: No such file or directory
make[2]: *** [arpack-ng-3.1.3/checked] Error 127
make[1]: *** [julia-release] Error 2
make: *** [release] Error 2

Looks like we are missing an appropriate rpath somewhere...

Sorry about this. I think MKL usage is common enough that it would be nice to add it to our test suites - but the license is perhaps not permissive enough.

I think the MKL can be used for free for non-commercial applications on Linux. I also think that we could afford to buy a developer license and ship MKL with Julia.

Shipping with julia will need a little more work - since OpenBLAS handles AMD architectures too. I have always wondered whether we can distribute - since this effectively makes MKL freely available then to anybody. I am sure there is a catch.

In any case, the license is permissive enough for us to use it for testing.

e8a94c0 fixed the build. I now get a slew of library warnings when I actually use a BLAS method.

@ViralBShah You can distribute the MKL libraries if you have a commercial license.

It would be good to get BLAS performance tests going, before we decide to put effort into distributing MKL.

@ViralBShah A follow-up on the distribution question: it is answered in Intel's MKL FAQ: http://software.intel.com/en-us/articles/intel-math-kernel-library-licensing-faq

Thanks.

We should certainly work on including MKL in the Mac and Windows distributions, along with OpenBLAS.
