I’m using cuSolver for solving an Ax = b problem using sparse matrix. The matrix is sized 18722 x 18722 with 139393 non zero elements. However, the function cusolverSpDcsrlsvqr is raising a CUSOLVER_STATUS_ALLOC_FAILED error. It’s strange because just before I call this function, the device has about 900Mb of free memory.
Does anyone knows which problem it could be?
Thanks so much.
