Hi,
I don't know if this makes much sense, but I tried to use update-alternatives on linux to make all the symlinks for libblas.so, libblas.so.3gf, liblapack.so and liblapack.so.3gf point to libmkl_rt.so. I was hoping that this way numpy will use the mkl implementation of blas operations without needing to recompile it. But, as it turns out, the loader is having some trouble with the multi-threading library, which I expected to be libmkl_gnu_thread.so instead of libmkl_intel_thread.so.
python -c "from numpy import zeros; a = zeros((17,17)); b = a.dot(a)"
python: symbol lookup error: /opt/intel/mkl/lib/intel64/libmkl_intel_thread.so: undefined symbol: omp_get_num_procs
I am using mkl 11.0 update 5, which I upgraded from mkl 11.0 update 2, which didn't work either. Everything is on 64bits. I also noticed that for matrices smaller than (17, 17) ther error doesn't occur.
Thanks,
Bogdan

Shouldn't one of the appropriate libraries be loaded by libmkl_rt.so?

yes, it will load libiomp via dlopen == > you need to add <composer_xe_install_path>\compiler/lib/intel64\ to your systems paths.

Thanks a lot. I got it fixed by adding the path to loader's search paths in /etc/ld.so.conf.d
