CUSPATIAL_CHECK_CUDA

#define CUSPATIAL_CHECK_CUDA

(

stream

)

Value:

  do {                                                 \
    CUSPATIAL_CUDA_TRY(cudaStreamSynchronize(stream)); \
    CUSPATIAL_CUDA_TRY(cudaPeekAtLastError());         \
  } while (0);

Debug macro to check for CUDA errors.

In a non-release build, this macro will synchronize the specified stream before error checking. In both release and non-release builds, this macro checks for any pending CUDA errors from previous calls. If an error is reported, an exception is thrown detailing the CUDA error that occurred.

The intent of this macro is to provide a mechanism for synchronous and deterministic execution for debugging asynchronous CUDA execution. It should be used after any asynchronous CUDA call, e.g., cudaMemcpyAsync, or an asynchronous kernel launch.

CUSPATIAL_CUDA_TRY

#define CUSPATIAL_CUDA_TRY

(

call

)

Value:

  do {                                                                 \
    cudaError_t const status = (call);                                 \
    if (cudaSuccess != status) {                                       \
      cudaGetLastError();                                              \
      cuspatial::detail::throw_cuda_error(status, __FILE__, __LINE__); \
    }                                                                  \
  } while (0);

Error checking macro for CUDA runtime API functions.

Invokes a CUDA runtime API function call, if the call does not return cudaSuccess, invokes cudaGetLastError() to clear the error and throws an exception detailing the CUDA error that occurred

CUSPATIAL_EXPECTS

#define CUSPATIAL_EXPECTS	(		cond,
			reason )

Value:

  (!!(cond)) ? static_cast<void>(0)                                           \
             : throw cuspatial::logic_error("cuSpatial failure at: " __FILE__ \
                                            ":" CUSPATIAL_STRINGIFY(__LINE__) ": " reason)

Macro for checking (pre-)conditions that throws an exception when a condition is violated.

------------------------------------------------------------------------—*

Example usage:

CUSPATIAL_EXPECTS(lhs->dtype == rhs->dtype, "Column type mismatch");

Parameters

[in]	cond	Expression that evaluates to true or false
[in]	reason	String literal description of the reason that cond is expected to be true

Exceptions

cuspatial::logic_error

if the condition evaluates to false.

Definition at line 76 of file error.hpp.

CUSPATIAL_FAIL

#define CUSPATIAL_FAIL

(

reason

)

Value:

  throw cuspatial::logic_error("cuSpatial failure at: " __FILE__ \
                               ":" CUSPATIAL_STRINGIFY(__LINE__) ": " reason)

Indicates that an erroneous code path has been taken.

------------------------------------------------------------------------—*

In host code, throws a cuspatial::logic_error.

Example usage:

CUSPATIAL_FAIL("Non-arithmetic operation is not supported");

Parameters

reason

String literal description of the reason

Definition at line 119 of file error.hpp.

CUSPATIAL_HOST_DEVICE_EXPECTS

#define CUSPATIAL_HOST_DEVICE_EXPECTS	(		cond,
			reason )   CUSPATIAL_EXPECTS(cond, reason)

Macro for checking (pre-)conditions that throws an exception when a condition is violated.

------------------------------------------------------------------------—*

Example usage:

CUSPATIAL_HOST_DEVICE_EXPECTS(lhs->dtype == rhs->dtype, "Column type mismatch");

Parameters

[in]	cond	Expression that evaluates to true or false
[in]	reason	String literal description of the reason that cond is expected to be true

(if on host)

Exceptions

cuspatial::logic_error

if the condition evaluates to false. (if on device)

program terminates and assertion error message is printed to stderr.
