ippStsNotSupportedCpu
This warning is about the runtime environment. It may appear during initialization or dispatch when the processor is not among the CPUs supported by the linked IPP release or selected optimized path.
Differentiate it from a missing instruction-set feature requested manually. The useful log fields are CPU vendor, family/model, feature mask, IPP version, and whether dispatch was automatic or forced.
Diagnostic focus
- Check the minimum CPU requirements of the IPP release you deploy.
- Look for virtualization or BIOS settings that mask SIMD capabilities.
- Do not retry the same primitive with different buffers; the mismatch is platform-level.
