%description
Portable Computing Language (pocl) is an implementation of the OpenCL standard
which can be adapted for new targets and devices, both for homogeneous CPU and
heterogenous GPUs/accelerators.

pocl uses Clang as an OpenCL C frontend and LLVM for the kernel compiler
implementation, and as a portability layer. If your desired target has an LLVM
backend, it should be possible to get OpenCL support by using pocl.

pocl yields improved performance portability by using a kernel compiler that
can generate multi-work-item work-group functions that exploit various types of
parallel hardware resources, such as VLIW, superscalar, SIMD, SIMT, multicore
and multithread.
