Is it possible to switch between BLAS libraries without recompiling program?

Question

For example can I have Atlas, OpenBlas, MKL installed on my Ubuntu 14.04 at the same time and switch between them without recompiling Caffe?

Answer 1

Sure, you have to have them installed, and on Ubuntu/Debian issue command

update-alternatives --config libblas.so.3

You'll get numbered list of alternatives and could switch between them easily
