The default optimized code at IA-32 will be removed in the Intel® MKL 11.0

Intel MKL 10.3 default optimized code at IA-32 runs on the processors that do not support Intel® SSE2 instructions(Intel® Pentium® Ⅲ processors, or Intel compatible processors without SSE2 instructions, etc.).

In the forthcoming Intel MKL 11.0, the default optimized code for IA-32 will be removed. The minimum processor requirement will be the processors supporting Intel SSE2 instructions, and Intel MKL functions will return an error on the processors without Intel SSE2 support.
