This is a status type returned by the library functions and it can have the following values.

Variants

CUSOLVER_STATUS_SUCCESS = 0

The operation completed successfully.

CUSOLVER_STATUS_NOT_INITIALIZED = 1

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 cusolverDnCreate prior to the function call; and check that the hardware, an appropriate version of the driver, and the cuSolver library are correctly installed.

CUSOLVER_STATUS_ALLOC_FAILED = 2

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.

CUSOLVER_STATUS_INVALID_VALUE = 3

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.

CUSOLVER_STATUS_ARCH_MISMATCH = 4

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 5.0 or above.

CUSOLVER_STATUS_MAPPING_ERROR = 5

CUSOLVER_STATUS_EXECUTION_FAILED = 6

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.

CUSOLVER_STATUS_INTERNAL_ERROR = 7

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.

CUSOLVER_STATUS_MATRIX_TYPE_NOT_SUPPORTED = 8

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.

CUSOLVER_STATUS_NOT_SUPPORTED = 9

The parameter combination is not supported, for example batched version is not supported or M < N is not supported.

To correct: consult the documentation, and use a supported configuration.

CUSOLVER_STATUS_ZERO_PIVOT = 10

CUSOLVER_STATUS_INVALID_LICENSE = 11

CUSOLVER_STATUS_IRS_PARAMS_NOT_INITIALIZED = 12
