CUDA integer methods?

[cdeterman]

Are the templates for CUDA int methods not provided in ViennaCL? I am getting many errors, such as the following, during some compilation.

/usr/local/lib/R/site-library/RViennaCL/include/viennacl/linalg/cuda/matrix_operations_row.hpp(1013): error: calling a __host__ function("std::sqrt<int> ") from a __global__ function("viennacl::linalg::cuda::matrix_row_unary_element_op_kernel< ::viennacl::op_sqrt, int> ") is not allowed

/usr/local/lib/R/site-library/RViennaCL/include/viennacl/linalg/cuda/matrix_operations_col.hpp(983): error: calling a __host__ function("std::sqrt<int> ") from a __global__ function("viennacl::linalg::cuda::matrix_col_unary_element_op_kernel< ::viennacl::op_sqrt, int> ") is not allowed

/usr/local/lib/R/site-library/RViennaCL/include/viennacl/linalg/cuda/matrix_operations_row.hpp(1013): error: calling a __host__ function("std::sin<int> ") from a __global__ function("viennacl::linalg::cuda::matrix_row_unary_element_op_kernel< ::viennacl::op_sin, int> ") is not allowed

Several more are omitted for the sake of space. Basically all the blas 1 methods.

I see the macro VIENNACL_CUDA_GENERATE_UNARY_OP in the viennacl/linalg/cuda/common.hpp file but I fail to see what dictates whether it generates a different type when all the blas 1 methods are provided for the int type in OpenCL.

Or is this perhaps a CUDA thing where only float and double are available methods?
