llvm dev - Aug 2013 - [LLVMdev] Portable Computing Language (pocl) v0.8 released

Portable Computing Language (pocl) v0.8 released

Pocl's goal is to become an efficient open source (MIT-licensed)
implementation of the OpenCL 1.2 (and soon OpenCL 2.0) 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,...).

This release adds support for LLVM/Clang 3.3, employs inner loop parallelization
in the kernel compiler, uses Vecmathlib for inlineable efficient math library
implementations, contains plenty of bug fixes, and provides several new OpenCL
API implementations.

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 0.8 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.
