add parallel/pocl

OpenCL (Open Computing Language) is an open, royalty-free standard for
cross-platform, parallel programming of diverse accelerators found in
supercomputers, cloud servers, personal computers, mobile devices and embedded
platforms.

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.
