ippStsSmallerCodebook
Investigate Intel IPP created a codebook smaller than cdbkSize at the first returning call, before a wrapper substitutes a generic message. The codebook-generation primitive completed but could not produce the requested number of distinct usable entries from the supplied data.
Operational meaning
Intel IPP assigns meaning to the sign of IppStatus: negative is error, zero is clean completion, and positive is warning with potentially usable output. Output validation is therefore inseparable from status handling.
Intel IPP uses negative values for errors, zero for no warning/error, and positive values for warnings that can accompany completed output. Do not treat every nonzero status as an aborted operation. Keep the numeric value, declared return type, and first returning operation together with This result; the same integer can belong to a different status namespace in another API.
Build a reproducible record
| Capture | Diagnostic value |
|---|---|
| Function, requested cdbkSize, returned size, sample count, distinct-vector count, dimension, and initialization. | Identifies the concrete object and operation associated with Intel IPP created a codebook smaller than cdbkSize. |
| IppStatus sign and value interpreted using the same IPP headers as the linked library. | Separates argument or lifecycle state from the provider beneath the returned status. |
| Output-buffer state and checksum before and after the call. | Creates a stable before-and-after comparison. |
| Reference result or invariant appropriate to the primitive domain. | Shows whether that result is the first result or a translated summary. |
For This result preserve IppStatus sign and value interpreted using the same IPP headers as the linked library in an investigation of the original status before reinstalling, rebooting, clearing state, or substituting another device or provider. A success observed only after such a change is useful comparison data for It but it does not identify the original cause.
Checks that separate the causes
- Train on synthetic distinct vectors whose count exceeds cdbkSize. Record the first returned status and any state transition observed.
- Run one boundary input and one known-good control without changing dispatch/library version. Treat a changed result as a new boundary rather than automatic resolution of the failing return.
- Check the status immediately; IPP does not preserve a global last-status value. Repeat the original supported operation so the check remains relevant to the original call.
Resolution criteria
Targeted correction. Reduce requested size or improve/diversify training data and handle the returned actual size explicitly. For This result modify only the object, argument, policy, provider, or lifecycle state identified by the collected evidence.
Acceptance criterion. Returned codebook size meets the chosen contract and quality metrics remain stable on held-out data. Re-run the original operation that produced This result under its original identity and supported configuration, then keep one negative control that still produces the expected neighboring outcome.
