Btw, concerning OpenCL I recently found this IBM research project [1]. It not only abstracts OpenCL but OpenMP, CUDA and FPGA programming too. So you don't have to deal with low level library programming. Just thought I share that link with you (I am not recommending using that project as part of Apache Tuscany)..
