The use of specialized hardware, such as accelerators or coprocessors offers an interesting approach to overcoming the physical limits encountered by processor architects. As a result, many machines are now equipped with one or several accelerators (e.g. a GPU), in addition to the usual processor(s). While significant efforts have been devoted to offloading computation onto such accelerators, very little attention has been paid to portability concerns on the one hand, and to the possibility of having heterogeneous accelerators and processors interact on the other hand.
│ │ │StarPU is a runtime system that provides support for heterogeneous multicore architectures. It not only offers a unified view of the computational resources (i.e. CPUs and accelerators simultaneously) but also takes care of efficiently mapping and executing tasks onto an heterogeneous machine while transparently handling low-level issues such as data transfers in a portable manner.
│ │ │StarPU is a software tool designed to enable programmers to harness the computational capabilities of both CPUs and GPUs, all while sparing them the need to meticulously adapt their programs for specific target machines and processing units.
