In this paper, we present a new backend of an llc compiler that produces code for GPUs. We have also implemented a software architecture that eases the development of new backends. Our design represents an intermediate layer between a high-level parallel language and different hardware architectures. We evaluate our development by comparing the OpenMP and llc parallelizations of three different algorithms. In every case, the probable performance loss with respect to a direct CUDA implementation is clearly compensated by a significantly smaller development effort.
