Exascale computing challenges and their application to a production datacenter

Abstract

In this talk I will outline the main challenges to achieving useable Exascale computer systems and discuss some of the approaches being taken to address them. These include the requirement to cut the power needed by the system, ensure the reliability of the system and specify programming models that will effectively utilize the system's potential. I will then draw on an example based on the computational core of an investment house fixed incomes desk. This example highlights a system that can reliably use a hybrid set of computational resources to price complicated bonds and to measure their risk profile. This is one type of code that can take advantage of any reasonable system with only minor modification.
