AUTOMATIC ERROR CHECKING 10.1. Checking API Errors CUDA-GDB can automatically check the return code of any driver API or runtime API call. If the return code indicates an error, the debugger will stop or warn the user. The behavior is controlled with the set cuda api_failures option. ...

control The runtime API eases device code management by providing implicit initialization, context management, and module management. This leads to simpler code, but it also lacks the level of control that the driver API has. In comparison, the driver API offers more fine-grained control, ...

When hardware buffer overflows, CUPTI returns the out of memory error code. And a new field hardwareBufferFull added in the struct CUpti_PCSamplingData is set to differentiate it from other out of memory cases. User can either increase the hardware buffer size or flush the hardware buffer at...
