The Road to Exascale: Challenges and Opportunities

The increasing complexity of scientific disciplines is continuously driving the need for more powerful computing machines. While  petascale machines were once adequate, we are now witnessing a demand for the exascale machines that will enable the next wave of scientific discoveries. Clearly, building an efficient Exascale machine is no small feat. In this talk, I will discuss the challenges involved in this pursuit  and discuss possible solutions. The creation of an Exascale system will have major impacts in many key areas of science, national security, finance, medicine, and many more.
