Dynamically linking MKL

Rob_R_1 — Tue, 02 Jul 2013 00:11:03 GMT

Hi is it possible to dynamically link MKL? In particular I want a drop in replacement for blas and lapack on my system. With ATLAS I am able to just create symlinks to the appropriate libraries for libblas.so and liblapack.so and most applications will work correctly. Is this possible with any of the MKL libraries? Thanks.

Please tell us what platform

Please tell us what platform are you using? >>... Is this possible with any of the MKL libraries?.. Here is a very generic answer on your question: Yes, MKL libraries could be dynamically linked.

Dynamic link is what you get

Dynamic link is what you get with the plain -mkl option with Intel compilers. It's probably possible to switch among ATLAS and MKL simply by adjusting LD_LIBRARY_PATH, if you limit yourself to the basics.

My apologies, I should have been more specific. I am on an intel64 platform.

I was able to get things to work by symlinking libblas.so -> libmkl_rt.so and liblapack.so.3 -> libmkl_rt.so. I also needed to make sure that I source mklvars.sh. Things seem to perform quite well and I haven't come across any issues yet.
