I know that Codeplay has a Parallelism-TS implementation based on OpenCL
SYCL.

I guess they will talk about this during http://www.iwocl.org/ next
month where there will be several sessions on SYCL.

They presented their Clang/LLVM-based SYCL implementation during the
Workshop on the LLVM Compiler Infrastructure in HPC at SuperComputing
2014
http://www.codeplay.com/public/uploaded/publications/SC2014_LLVM_HPC.pdf
but I just checked and it does not talk about Parallelism-TS yet.
