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. |

Workflow and product fit
Compute Sanitizer investigates runtime correctness; Nsight Compute investigates kernel performance. A kernel can require both kinds of analysis. Establish correctness and a reproducible test before interpreting performance observations.
Profiling, interactive debugging and runtime correctness checking answer different development questions. These tools can be used together and are not interchangeable performance or reliability guarantees. Confirm GPU, driver, runtime, API and operating-system support.

Cost and migration planning
For NVIDIA Compute Sanitizer, include compatible resources, tool access and engineering investigation. For NVIDIA Nsight Compute, include compatible GPU resources, tooling 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.
