==== MKL ====

To get the compiler and linker options for using the MKL you can use the

As on all non-intel chips, MKL will not automagically select the correct code path for fastest exectuion. 
The same holds true for multi-code-path (fat) binaries generated by the intel compilers (ifort/icc).

However, for MKL there is a trick to work around this problem by setting an undocumented environment variable: **''MKL_DEBUG_CPU_TYPE=N''**, where ''**N**'' is an integer that corresponds to a vectorization set. **''N=5''** should force MKL to use AVX2 instructions, instead of the default SSE2 on non-intel chips.
