# MKL specific Linux configuration
# We have tested Kaldi with MKL version 10.2 on Linux/GCC and Intel(R) 64
# architecture (also referred to as x86_64) with LP64 interface layer.
# The linking flags for MKL will be very different depending on the OS,
# architecture, compiler, etc. used. The correct flags can be obtained from
# http://software.intel.com/en-us/articles/intel-mkl-link-line-advisor/
# Use the options obtained from this website to manually configure for other
# platforms using MKL.
