StarPU in Julia

Julia is a modern language for parallelism and simulation that aims to ease the effort for developping high performance codes. In this context, we have started to develop a StarPU binding inside Julia. It is now possible to launch StarPU kernels inside Julia, either given as libraries, or described in Julia directly. Julia has the advantage to simplify significantly the syntax required to express the task and data management in StarPU (defining a new scope for StarPU, using automatic desallocation of buffers, ...).

Besides, using the introspection properties of Julia, the kernels written in Julia are automatically translated in both C codes and CUDA codes. Some preliminary experimental results show encouraging speedups on some limited codes. This is a work in progress, developped with A.Juven and M.Keryell.
