Sparse Blas with extended precision

Hi,

as I'm trying to calculate eigenvalues with ARPACK of a very big matrix, I am in the need of efficient sparse matrix-vector multiplication routines. Unfortunately, at the same time I need more precision than just double precision. Now my question: Is there any support of the MKL sparse Blas matrix-vector multiplication routines (in particular mkl_*bsrgemv) for complex(16) matrices and vectors or some kind of workaround for mkl_zbsrgemv to gain more precision?

Thanks,
Martin

In complex(16) compilation, public source code would do as well as could be done by detailed hand coding.

yes,mkl doesn't support quad precision data types.
