n creates a practical challenge for neocloud customers. A provider may maintain a tested baseline for its standard service, yet a customer may require a newer framework build or a specialised communication library. That request changes the configuration under evaluation, even if the provider does not replace a single physical accelerator. Compatibility information for the underlying GPU therefore cannot establish that the complete application will run correctly. The relevant question concerns the exact combination of software, configuration and hardware that the workload will use. A reliable answer requires evidence about that combination, not a general assurance about hardware capability.
