ViennaCL does not provide a QR decomposition of sparse matrices. Such algorithms are hard to parallelize well (and possibly impossible to parallelize on GPUs). I recommend 'standard' CPU-based linear algebra libraries for this.

Dear Karli,
I am woundering if it would be possible to run a QR decomposition of a compressed matrix (i only saw that you did it for dense matrix)
Best regards,
