To cite opencltools as software, use the first entry. If your work uses the likelihood subgradient envelope computation illustrated in the glmbayes examples (f2_f3_* kernels), also cite Nygren and Nygren (2006). If you report OpenCL GPU execution, cite Stone et al. (2010). Cite glmbayes separately when describing that downstream application rather than the opencltools runtime layer.
