Functions

__host__ ​cudaError_t cudaDriverGetVersion ( int* driverVersion )

Returns the latest version of CUDA supported by the driver.

Parameters

driverVersion

- Returns the CUDA driver version.

Returns

cudaSuccess, cudaErrorInvalidValue

Description

Returns in *driverVersion the latest version of CUDA supported by the driver. The version is returned as (1000 major + 10 minor). For example, CUDA 9.2 would be represented by 9020. If no driver is installed, then 0 is returned as the driver version.

This function automatically returns cudaErrorInvalidValue if driverVersion is NULL.

Note:

• Note that this function may also return error codes from previous, asynchronous launches.

• Note that this function may also return cudaErrorInitializationError, cudaErrorInsufficientDriver or cudaErrorNoDevice if this call tries to initialize internal CUDA RT state.

• Note that as specified by cudaStreamAddCallback no CUDA function may be called from callback. cudaErrorNotPermitted may, but is not guaranteed to, be returned as a diagnostic in such case.

__host__ ​ __device__ ​cudaError_t cudaRuntimeGetVersion ( int* runtimeVersion )

Returns the CUDA Runtime version.

Parameters

runtimeVersion

- Returns the CUDA Runtime version.

Returns

cudaSuccess, cudaErrorInvalidValue

Description

Returns in *runtimeVersion the version number of the current CUDA Runtime instance. The version is returned as (1000 major + 10 minor). For example, CUDA 9.2 would be represented by 9020.

As of CUDA 12.0, this function no longer initializes CUDA. The purpose of this API is solely to return a compile-time constant stating the CUDA Toolkit version in the above format.

This function automatically returns cudaErrorInvalidValue if the runtimeVersion argument is NULL.

Note:

• Note that this function may also return cudaErrorInitializationError, cudaErrorInsufficientDriver or cudaErrorNoDevice if this call tries to initialize internal CUDA RT state.

• Note that as specified by cudaStreamAddCallback no CUDA function may be called from callback. cudaErrorNotPermitted may, but is not guaranteed to, be returned as a diagnostic in such case.
