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 open-source OpenCL implementation,
another major goal of this project is improving performance portability
of OpenCL programs with the kernel compiler and the task runtime,
reducing the need for target-dependent manual optimizations.

Upstream pocl currently supports various CPUs, NVIDIA GPUs via libcuda,
HSA-supported GPUs and TCE ASIPs (experimental, see
http://openasip.org), with various known private adopters as well.

Release Highlights

* Support for Clang/LLVM 9.0 (support for older than 6.0 dropped).
* It's possible to build relocatable Pocl.
* Improved SPIR and SPIR-V support for CPU device.
* Initial implementation of a custom device / accelerator interface

Please note that there's an official pocl "maintenance policy" in place.
This text describes the policy and how you can get your favourite
project that uses OpenCL to remain regression free in the future pocl



Most of the code that landed to the pocl code base during this release
cycle was produced for the needs of research projects funded by various
sources. Customized Parallel Computing research group of Tampere
University, Finland likes to thank the Academy of Finland (funding
decision 297548), ECSEL JU project FitOptiVis (project number 783162)
and HSA Foundation for funding most of the development work in this
release. Much appreciated!
