cusolverStatus_t

[mboudagh]

Hey all, I have a very general question about cusolverStatus_t, and I suppose there are many similar questions in the forum. But would you mind explaining the integer values for each case of cusolverStatus_t?
I suppose, CUSOLVER_STATUS_SUCCESS is 0, by that the integer values for all would be in range of 0 to 7 for CUSOLVER_STATUS_SUCCESS, CUSOLVER_STATUS_NOT_INITIALIZED, CUSOLVER_STATUS_ALLOC_FAILED, …, and finally CUSOLVER_STATUS_MATRIX_TYPE_NOT_SUPPORTED.
Is my understanding correct?

For an exact answer, refer to the cusolver_common.h that you’re using with your particular version of the CUDA Toolkit.

The following is from CUDA 11.7.

typedef enum{
    CUSOLVER_STATUS_SUCCESS=0,
    CUSOLVER_STATUS_NOT_INITIALIZED=1,
    CUSOLVER_STATUS_ALLOC_FAILED=2,
    CUSOLVER_STATUS_INVALID_VALUE=3,
    CUSOLVER_STATUS_ARCH_MISMATCH=4,
    CUSOLVER_STATUS_MAPPING_ERROR=5,
    CUSOLVER_STATUS_EXECUTION_FAILED=6,
    CUSOLVER_STATUS_INTERNAL_ERROR=7,
    CUSOLVER_STATUS_MATRIX_TYPE_NOT_SUPPORTED=8,
    CUSOLVER_STATUS_NOT_SUPPORTED = 9,
    CUSOLVER_STATUS_ZERO_PIVOT=10,
    CUSOLVER_STATUS_INVALID_LICENSE=11,
    CUSOLVER_STATUS_IRS_PARAMS_NOT_INITIALIZED=12,
    CUSOLVER_STATUS_IRS_PARAMS_INVALID=13,
    CUSOLVER_STATUS_IRS_PARAMS_INVALID_PREC=14,
    CUSOLVER_STATUS_IRS_PARAMS_INVALID_REFINE=15,
    CUSOLVER_STATUS_IRS_PARAMS_INVALID_MAXITER=16,
    CUSOLVER_STATUS_IRS_INTERNAL_ERROR=20,
    CUSOLVER_STATUS_IRS_NOT_SUPPORTED=21,
    CUSOLVER_STATUS_IRS_OUT_OF_RANGE=22,
    CUSOLVER_STATUS_IRS_NRHS_NOT_SUPPORTED_FOR_REFINE_GMRES=23,
    CUSOLVER_STATUS_IRS_INFOS_NOT_INITIALIZED=25,
    CUSOLVER_STATUS_IRS_INFOS_NOT_DESTROYED=26,
    CUSOLVER_STATUS_IRS_MATRIX_SINGULAR=30,
