To cite nmathopencl in publications use the first entry for the
OpenCL-ported nmath library. If you report OpenCL GPU execution, cite
Stone et al. (2010). Cite Nygren and Nygren (2006) for likelihood
subgradient methodology when relevant to envelope-based GLM simulation
work. Host/runtime OpenCL tooling is provided by the imported package
opencltools (cite separately if used).
