Variables

CUDBGResult ( *CUDBGAPI_st::resumeDevice )( uint32_t dev )

Resume a suspended CUDA device. Since CUDA 3.0.

suspendDevice

singleStepWarp

Parameters

dev

- device index

Returns

CUDBG_SUCCESS, CUDBG_ERROR_INVALID_DEVICE, CUDBG_ERROR_RUNNING_DEVICE, CUDBG_ERROR_UNINITIALIZED

CUDBGResult ( *CUDBGAPI_st::resumeWarpsUntilPC )( uint32_t devId, uint32_t sm, uint64_t warpMask, uint64_t virtPC )

Inserts a temporary breakpoint at the specified virtual PC, and resumes all warps in the specified bitmask on a given SM. As compared to CUDBGAPI_st::resumeDevice, CUDBGAPI_st::resumeWarpsUntilPC provides finer-grain control by resuming a selected set of warps on the same SM. The main intended usage is to accelerate the single-stepping process when the target PC is known in advance. Instead of single-stepping each warp individually until the target PC is hit, the client can issue this API. When this API is used, errors within CUDA kernels will no longer be reported precisely. In the situation where resuming warps is not possible, this API will return CUDBG_ERROR_WARP_RESUME_NOT_POSSIBLE. The client should then fall back to using CUDBGAPI_st::singleStepWarp or CUDBGAPI_st::resumeDevice. Since CUDA 6.0.

Parameters

devId

- device index

sm

- the SM index

warpMask

- the bitmask of warps to resume (1 = resume, 0 = do not resume)

virtPC

- the virtual PC where the temporary breakpoint will be inserted

Returns

CUDBG_SUCCESS CUDBG_ERROR_INVALID_ARGS CUDBG_ERROR_INVALID_DEVICE CUDBG_ERROR_INVALID_SM CUDBG_ERROR_INVALID_WARP_MASK CUDBG_ERROR_WARP_RESUME_NOT_POSSIBLE CUDBG_ERROR_UNINITIALIZED

CUDBGResult ( *CUDBGAPI_st::singleStepWarp )( uint32_t dev, uint32_t sm, uint32_t wp, uint32_t nsteps, uint64_t* warpMask )

Single step an individual warp nsteps times on a suspended CUDA device. Only the last instruction in a range should be a control flow instruction. Since CUDA 7.5.
