These are hypothetical scenarios with explicit assumptions. They do not establish equal capabilities, measured usability or a negotiated price.
| Requirement | Proposed exercise | Accept when |
|---|---|---|
| Environment scope | Record the sample app, GPU, driver, runtime, APIs and build configuration. | The selected tool documents support for the actual environment. |
| Known task | Run the authorised sample against a predefined profiling or debugging question. | The observation answers the stated question without being treated as a benchmark guarantee. |
| Reproduction | Repeat the sample with saved inputs and recorded settings. | The developer can reproduce and interpret the relevant observation. |
| Tool handover | Document how the finding enters code review or further investigation. | The team understands which questions require other profiling, debugging or testing tools. |

Cost and migration planning
For NVIDIA Compute Sanitizer, include compatible resources, tool access and engineering investigation. For NVIDIA CUDA-GDB, include compatible hardware, build tools and developer time. Define the same task, supported configuration and operating environment, then confirm current software and connected-service terms.
Use an authorised sample application and a known test case on compatible non-production hardware. Record build flags, driver and runtime versions, then interpret observations with the responsible developer. These are proposed exercises; no benchmarks were run.
