For decades, CMOS technology provided exponential improvements in transistor density and energy consumption, allowing hardware architects to focus on removing picoseconds from processor clock cycles and adding megabytes to on-chip caches. Unfortunately, we are now in a phase where transistor cost and energy consumption are barely scaling. Consequently, the new name of the game is accounting for and optimizing every picojoule the hardware consumes. This talk will describe the challenges and opportunities in designing high performance, yet energy efficient systems. Specifically, we will discuss hardware and software specialization and raising utilization in datacenter systems. While these approaches represent a non-trivial departure from the way we design and use systems today, combined they can provide improvements equivalent to a few decades of Moore's law scaling.
