+PoCL is a portable open source (MIT-licensed) implementation of the OpenCL
standard (1.2 with some 2.0 features supported). In addition to being an easily
portable multi-device (truely heterogeneous) open-source OpenCL implementation,
a major goal of this project is improving interoperability of diversity of
OpenCL-capable devices by integrating them to a single centrally orchestrated
platform. Also one of the key goals longer term is to enhance performance
portability of OpenCL programs across device types utilizing runtime and
compiler techniques.
+
+Upstream PoCL currently supports various CPUs, NVIDIA GPUs via libcuda,
HSA-supported GPUs and TCE ASIPs (experimental, see: OpenASIP). It is also
known to have multiple (private) adaptations in active production use.
+
+PoCL uses Clang as an OpenCL C frontend and LLVM for kernel compiler
implementation, and as a portability layer. Thus, if your desired target has an
LLVM backend, it should be able to get OpenCL support easily by using PoCL.
