Intel® IPP provides optimization code for the Intel® Advanced Vector Extensions 512 (Intel® AVX-512), Intel® Advanced Vector Extensions 2(Intel® AVX2), and Intel® Advanced Vector Extensions (Intel® AVX) instruction sets. To use these instructions sets, explicit operating system support is required to protect the vectorization registers for the applications.
Intel® IPP requires the following versions of operating systems to enable Intel® AVX, Intel® AVX2, and Intel® AVX-512 support:
Intel® IPP functions dispatch the processor-specific optimized code according to both CPU type and operating system support status. One dispatching problem was identified in the recent IPP releases, and was fixed in the latest IPP 2018 Update 1.1 release. The problems only happen on the following systems:
The Intel(R) IPP functions may report "illegal instructions” errors at the runtime with such problems.
A new versions of Intel® IPP 2018 Update 1.1 release is available, which includes the fix of the problems. To get this package:
If your applications can not update to Intel® IPP 2018 Update 1.1 or a later version of Intel® IPP, the workaround is to use the following APIs to manually dispatch the optimization code for your target systems:

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
