This paper proposes XcalableACC, a directive-based language extension to program APCs. XcalableACC is a combination of two existing directive-based languages, XcalableMP and OpenACC, and has two additional functions: data/work mapping among multiple accelerators and direct communication between accelerators. The result of the preliminary evaluation shows that XcalableACC is a promising means to program APCs.=0A=0AIn our poster, the basic concept of XcalableACC and the result of preliminary evaluation will be presented.
