  <dc:title>'OpenCL'-Ported R 'Mathlib' for GPU-Accelerated Packages</dc:title>
  <dc:title>R package nmathopencl version 0.8.3</dc:title>
  <dc:description>Ships statistical and mathematical routines from R internal
    'nmath' ('Mathlib') as 'OpenCL' C sources under directory 'inst/cl/', with R
    wrappers that use the GPU when 'OpenCL' is available at compile time and
    fall back to 'stats' equivalents otherwise. Aimed at package developers
    building custom kernels (for example Bayesian GLMs via suggested package
    'glmbayes') using 'opencltools' kernel loaders and related helpers. Contains
    translated shims, an illustrative GLM-related kernel subsystem, vignettes,
    and optional GPU acceleration. The ported routines are translated from the
    'nmath' ('Mathlib') and 'Rmath' sources of R Core Team (2026) "R: A
    Language and Environment for Statistical Computing"
    &lt;doi:10.32614/R.manuals&gt;. 'OpenCL' GPU execution follows the standard
    described in Stone, Gohara, and Shi (2010) &lt;doi:10.1109/MCSE.2010.69&gt;. The
    likelihood subgradient simulation methodology implemented by the
    illustrative GLM kernel subsystem is described in Nygren and Nygren (2006)
