ippStsWrongAffinitySettingErr
This status belongs to IPP core threading control, not to image, signal, or codec data. It indicates that the affinity setting being queried or changed is inconsistent with the state established through ippSetAffinity.
Affinity depends on the OpenMP low-level affinity interface and the process environment. Diagnostics should include the affinity type, thread count, OpenMP affinity variables, and whether another runtime or launcher already pinned threads.
Diagnostic focus
- Check OMP/KMP affinity environment variables before blaming the IPP primitive.
- Avoid mixing several independent pinning mechanisms without a clear ownership rule.
- Reproduce with a minimal ippSetAffinity sequence if the failure is configuration-dependent.
