Field Summary

Fields

Modifier and Type	Field and Description
static int	CUSOLVER_STATUS_ALLOC_FAILED Resource allocation failed inside the cuSolver library.
static int	CUSOLVER_STATUS_ARCH_MISMATCH The function requires a feature absent from the device architecture; usually caused by the lack of support for atomic operations or double precision.
static int	CUSOLVER_STATUS_EXECUTION_FAILED The GPU program failed to execute.
static int	CUSOLVER_STATUS_INTERNAL_ERROR An internal cuSolver operation failed.
static int	CUSOLVER_STATUS_INVALID_LICENSE Invalid license
static int	CUSOLVER_STATUS_INVALID_VALUE An unsupported value or parameter was passed to the function (a negative vector size, for example).
static int	CUSOLVER_STATUS_MAPPING_ERROR Mapping error
static int	CUSOLVER_STATUS_MATRIX_TYPE_NOT_SUPPORTED The matrix type is not supported by this function.
static int	CUSOLVER_STATUS_NOT_INITIALIZED The cuSolver library was not initialized.
static int	CUSOLVER_STATUS_NOT_SUPPORTED Status not supported
static int	CUSOLVER_STATUS_SUCCESS The operation completed successfully.
static int	CUSOLVER_STATUS_ZERO_PIVOT Zero pivot

Field Detail

CUSOLVER_STATUS_SUCCESS

public static final int CUSOLVER_STATUS_SUCCESS

The operation completed successfully.

Constant Field Values

CUSOLVER_STATUS_NOT_INITIALIZED

public static final int CUSOLVER_STATUS_NOT_INITIALIZED

The cuSolver library was not initialized. This is usually caused by the lack of a prior call, an error in the CUDA Runtime API called by the cuSolver routine, or an error in the hardware setup. To correct: call cusolverCreate() prior to the function call; and check that the hardware, an appropriate version of the driver, and the cuSolver library are correctly installed.

Constant Field Values

CUSOLVER_STATUS_ALLOC_FAILED

public static final int CUSOLVER_STATUS_ALLOC_FAILED

Resource allocation failed inside the cuSolver library. This is usually caused by a cudaMalloc() failure. To correct: prior to the function call, deallocate previously allocated memory as much as possible.

See Also:

Constant Field Values

CUSOLVER_STATUS_INVALID_VALUE

public static final int CUSOLVER_STATUS_INVALID_VALUE

An unsupported value or parameter was passed to the function (a negative vector size, for example). To correct: ensure that all the parameters being passed have valid values.

See Also:

Constant Field Values

CUSOLVER_STATUS_ARCH_MISMATCH

public static final int CUSOLVER_STATUS_ARCH_MISMATCH

The function requires a feature absent from the device architecture; usually caused by the lack of support for atomic operations or double precision. To correct: compile and run the application on a device with compute capability 2.0 or above.

See Also:

Constant Field Values

CUSOLVER_STATUS_MAPPING_ERROR

public static final int CUSOLVER_STATUS_MAPPING_ERROR

Mapping error

See Also:

Constant Field Values

CUSOLVER_STATUS_EXECUTION_FAILED

public static final int CUSOLVER_STATUS_EXECUTION_FAILED

The GPU program failed to execute. This is often caused by a launch failure of the kernel on the GPU, which can be caused by multiple reasons. To correct: check that the hardware, an appropriate version of the driver, and the cuSolver library are correctly installed.

See Also:

Constant Field Values

CUSOLVER_STATUS_INTERNAL_ERROR

public static final int CUSOLVER_STATUS_INTERNAL_ERROR

An internal cuSolver operation failed. This error is usually caused by a cudaMemcpyAsync() failure. To correct: check that the hardware, an appropriate version of the driver, and the cuSolver library are correctly installed. Also, check that the memory passed as a parameter to the routine is not being deallocated prior to the routine's completion.

See Also:

Constant Field Values

CUSOLVER_STATUS_MATRIX_TYPE_NOT_SUPPORTED

public static final int CUSOLVER_STATUS_MATRIX_TYPE_NOT_SUPPORTED

The matrix type is not supported by this function. This is usually caused by passing an invalid matrix descriptor to the function. To correct: check that the fields in descrA were set correctly.

See Also:

Constant Field Values

CUSOLVER_STATUS_NOT_SUPPORTED

public static final int CUSOLVER_STATUS_NOT_SUPPORTED

Status not supported

Constant Field Values

CUSOLVER_STATUS_ZERO_PIVOT

public static final int CUSOLVER_STATUS_ZERO_PIVOT

Zero pivot

CUSOLVER_STATUS_INVALID_LICENSE

public static final int CUSOLVER_STATUS_INVALID_LICENSE

Invalid license
