The Kiwi system is targeted at making reconfig- like 2D parallel computing resource. This presents a valu- urable computing technology accessible to software en- able opportunity for efficiently expressing many compute gineers that are willing to express their computations as intensive calculations using more parallel computing re- parallel programs. Although there has been much work sources. However, heterogeneous systems also pose a on compiling sequential C-like programs to hardware by huge programming challenge because, up to now, differ- automatically ‘discovering’ parallelism, we work by ex- ent kinds of compute resources have been modeled and ploiting the parallel architecture communicated by the de- programmed in very different ways.
