The POWER CHALLENGEarray is a coarse-grained collection of large processor SMP nodes. This creates interesting parallelization opportunities for scalable applications. The NAS BT benchmark is a classical ADI-like application with non-trivial communication requirements. The coarse-grained distributed feature of the POWER CHALLENGEarray provides unique parallelization strategies. We explore the implementation of this benchmark on this machine and discuss the general implications for scalable application development
