（2）cusparseStatus_t  返回的值的含义及状态对应的修改措施

Value（String Type）	Int Type	Description
CUSPARSE_STATUS_SUCCESS	0	The operation completed successfully
CUSPARSE_STATUS_NOT_INITIALIZED	1	The cuSPARSE 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 cuSPARSE routine, or an error in the hardware setup To correct: call cusparseCreate() prior to the function call; and check that the hardware, an appropriate version of the driver, and the cuSPARSE library are correctly installed The error also applies to generic APIs ( Generic APIs reference) for indicating a matrix/vector descriptor not initialized
CUSPARSE_STATUS_ALLOC_FAILED	2	Resource allocation failed inside the cuSPARSE library. This is usually caused by a device memory allocation (cudaMalloc()) or by a host memory allocation failure To correct: prior to the function call, deallocate previously allocated memory as much as possible
CUSPARSE_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
CUSPARSE_STATUS_ARCH_MISMATCH	4	The function requires a feature absent from the device architecture To correct: compile and run the application on a device with appropriate compute capability
CUSPARSE_STATUS_EXECUTION_FAILED	5	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 cuSPARSE library are correctly installed
CUSPARSE_STATUS_INTERNAL_ERROR	6	An internal cuSPARSE operation failed To correct: check that the hardware, an appropriate version of the driver, and the cuSPARSE library are correctly installed. Also, check that the memory passed as a parameter to the routine is not being deallocated prior to the routine completion
CUSPARSE_STATUS_MATRIX_TYPE_NOT_SUPPORTED	7	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 cusparseMatDescr_t descrAwere set correctly
CUSPARSE_STATUS_NOT_SUPPORTED	8	The operation or data type combination is currently not supported by the function
