cuda::experimental::stf::cuda_try

Defined in include/cuda/experimental/__stf/utility/cuda_safe_call.cuh

template<typename Status>
void cuda::experimental::stf::cuda_try(Status status, const cuda::std::source_location loc = cuda::std::source_location::current())

Throws a cuda_exception if the given status is an error code.

The typical usage is to place a CUDA function call inside cuda_try, i.e. cuda_try(cudaFunc(args)) (the same way cuda_safe_call would be called). For example, cuda_try(cudaCreateStream(&stream)) is equivalent to cudaCreateStream(&stream), with the note that the former call throws an exception in case of error.

Template Parameters

Status – CUDA error code type, such as cudaError_t, cublasStatus_t, or cusolverStatus_t

Parameters

  • status – CUDA error code value, usually the result of a CUDA API call

  • loc – location of the call, defaulted
