Summary

Parallel computing now plays a significant role in delivering increased understanding of the complex fluid flow phenomena associated with the simulation of geometrically realistic engineering problems. However, we are now entering a new era where supercomputing performance has reached the petaflop level i.e. more than 1,000,000,000,000,000 floating point operations in one second have been achieved using the linpack benchmark. The task facing the scientific community now is how to achieve the goal of petaflop computing on real applications and this will require a substantial effort across a very broad spectrum of computational skills. It is therefore timely to focus on the challenges and opportunities offered by this scale of computing. To realise this level of capability is going to require a significant effort that ensures codes can scale to beyond 100,000 processors. It is clear that petaflop computing has re-invigorated the high performance computing community and there are many issues that now need to be confronted to enable applications to perform at this extreme level of computing power. This paper will highlight some of these issues.
