Is it possible to call cuSPARSE routines from kernel functions?

Is it possible to call cuSPARSE routines from the GPU, that is, from inside a kernel using dynamic parallelism?

libcublas_device.a enables to call cuBLAS routine from the GPU. I supposed libcusparse_device.a would exist and allow to call cuSPARSE routines from the GPU. However, it seems that file does not exist. Is this possible? If yes, how? If not, does NVIDIA plan to deliver such features in next GPU generations ?

Note : I run Unix (CentOs) + I use a "Tesla K20m" GPU (CUDA 5.5, Compute capability 3.5)

Quoting the cuSPARSE Library documentation for CUDA 6.5 (Release Candidate version):

The cuSPARSE library contains a set of basic linear algebra subroutines used for handling sparse matrices. It is implemented on top of the NVIDIA® CUDA™ runtime (which is part of the CUDA Toolkit) and is designed to be called from C and C++.

Accordingly, as of August 2014, you can't call cuSPARSE routines from kernel functions. The answer to your question is then: NO.
