Abstract
The next generation of supercomputers will be based on clusters of symmetric multi-processor (SMP) nodes interconnected by low-latency, high-bandwidth networks. Individual nodes will contain from 1 to 128 RISC/cache or vector processors in a shared or distributed-shared memory (DSM) configuration. These machines support a hybrid programming model combining sharedmemory threads (Open/MP) with distributed-memory message-passing (MPI). We discuss the various design considerations, trade-offs and constraints in the construction of high-performance atmospheric models capable of achieving one TeraFlop of sustained performance.
