%description
Runtime 'OpenCL' support for R package developers: probe hardware and
drivers, load and concatenate kernel sources, and manage
dependency-annotated '.cl' libraries, so packages like 'nmathopencl' and
other ported libraries can offer GPU acceleration without each
re-implementing the same plumbing. Vignettes use the 'glmbayes'
envelope-gradient example and likelihood subgradient methodology (Nygren
and Nygren, 2006, <doi:10.1198/016214506000000357>).
