[LLVMdev] Portable Computing Language (pocl) v0.9 released
Portable Computing Language (pocl) v0.9 released ------------------------------------------------ January 29, 2014. Pocl's goal is to become an efficient open source (MIT-licensed) implementation of the OpenCL 1.2 standard. In addition to producing an easily portable open-source OpenCL implementation, another major goal of this project is improving performance portability of OpenCL programs with compiler optimizations, reducing the need for target-dependent manual optimizations. At the core of pocl is the kernel compiler that consists of a set of LLVM passes used to statically transform kernels into work-group functions with multiple work-items, even in the presence of work-group barriers. These functions are suitable for parallelization in multiple ways (SIMD, VLIW, superscalar,...). The central changes in 0.9 are: -improved host/target CPU detection and targeted code generation -kernel compiler implemented by default by LLVM API calls instead of scripts -improvements to the handling of CL Images -several kernel compiler improvements. For the full list, see the change log. We consider pocl ready for wider scale testing, although the OpenCL 1.2 standard is not yet fully implemented, and it contains known bugs. The pocl 0.9 test suite compiles and runs most of the ViennaCL 1.3.1 examples, Rodinia 2.0.1 benchmarks, Parboil benchmarks, OpenCL Programming Guide book samples, VexCL test cases, Luxmark v2.0, and most of the AMD APP SDK v2.8 OpenCL samples, among others. Acknowledgements ---------------- We'd like to thank the Radio Implementation Research Team from Nokia Research Center, Finnish Funding Agency for Technology and Innovation (project "Parallel Acceleration", funding decision 40115/13) and Academy of Finland (funding decision 253087) for funding the development of this release.

Something to add to the release notes? :-) -bw On Jan 29, 2014, at 2:43 AM, Pekka Jääskeläinen <pekka.jaaskelainen at tut.fi> wrote:> Portable Computing Language (pocl) v0.9 released > ------------------------------------------------ > > January 29, 2014. > > Pocl's goal is to become an efficient open source (MIT-licensed) > implementation of the OpenCL 1.2 standard. > > In addition to producing an easily portable open-source OpenCL > implementation, another major goal of this project is improving > performance portability of OpenCL programs with compiler > optimizations, reducing the need for target-dependent manual > optimizations. > > At the core of pocl is the kernel compiler that consists of a set of > LLVM passes used to statically transform kernels into work-group > functions with multiple work-items, even in the presence of work-group > barriers.
