ippStsNoMemErr

This status is a memory availability failure. It may refer to memory required by the operation, workspace, internal tables or destination storage depending on the primitive.

It should be analyzed with the operation size and selected algorithm variant. A small input can still require a large context if the mode builds tables or plans.

Diagnostic focus

Record the input dimensions, precision, channel count and requested algorithm mode.
Check process address-space limits and memory fragmentation in long-running processes.
Where the API supports it, query buffer sizes explicitly before allocation.
