QR decomposition function on GPU

Accelerated Computing CUDA CUDA Programming and Performance

Hi All,
I need QR decomposition for symmetric tridiagonal matrices and Upper Hessenberg matrices. I see that this function is in cula library but the basic version supports only single precision floating point operations. Is there any available library or something where I can get the above mentioned function with double precision support??

Regards,
