cuSolver error

Hello everyone,

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.

Hi there,

I’ve ran into the exact same issue. Did you ever end up finding a solution?
