The non-threaded serial (or sequential) version of Intel® MKL is incorporated in the standard Intel® MKL package for versions 10.0 and later. There will not be any separate download available for the Intel® MKL serial version. Sequential version of MKL requires no Run-time library (RTL) layer, that is, no Compatibility OpenMP* or Legacy OpenMP* run-time library and does not respond to the environment variable OMP_NUM_THREADS. However, it is thread-safe, which means that you can use it in a parallel region from your own OpenMP* code. The sequential version may be helpful when using Intel® MKL with programs threaded with non-Intel compilers or in other situations where you may, for various reasons, need a non-threaded version of the library. To obtain sequential version of Intel® MKL, in the Threading layer, choose the *sequential.* library to link.
