Moore's Law is all about economics but there are alternative technologies on the way


22 Jun 2016 Frankfurt - On June 22, 2016 at the ISC 2016 Conference in Frankfurt, Germany, John Shalf from Lawrence Berkeley National Laboratory chaired a session titled "Scaling Beyond the End of Moore's Law". The session consisted of an introduction, three presentations and a panel discussion. Invited speakers were Josh Fryman from Intel who talked about the continuation of CMOS, Damian Steiger from ETH Zurich who addressed quantum computing, and Karlheinz Meier from the University of Heidelberg who proposed neuromorphic computing as an alternative for the end of Moore's Law.

John Shalf started the session by saying that Moore's Law has been driven largely by improvements in silicon lithography. For the past 50 years, we have seen a doubling of transistor density every 18 to 24 months consistently since the seventies of the past century. With that you get improvements and cost-efficiency and improvements in energy-efficiency that match the improvements in lithography and you also reach improvements in performance, John Shalf explained.

People over the past 50 years declared the end of Moore's Law over and over again to the point that Alan Kay stated: "I declare that Moore's Law will never end and therefore I want to be wrong once". Why does everybody now suddenly think that the end is near for Moore's Law, John Shalf asked himself. As we get down to the 5 nanometer technology and to atomic scale, lithography as a driver for Moore's Law might be at an end, according to some people.

These people claim that all the things that we have depended on in the past for improving performance, started to fail around 2004. This was another one of the drivers behind Moore's Law which in fact is an economic theory. They could not squeeze any more power out, they could not break up the clock frequencies, they could not improve single thread performance substantially. However, industry found a way to continue by doubling the number of cores each generation.

People said: "At least, we still have Moore's Law." This worked with lithography improvements. It was really a hard burden on the software and hardware architecture but the Exascale programme came out of this, John Shalf pointed out. By 2025, when we approximately will get to the 5 nanometer technology node, if we don't see any energy-efficiency improvement with each generation of lithography improvement, there is not really any impetus to continue to go down to 3 nanometers nor 1 nanometer. There will be no more gas in the tank when it comes to improve the performance, John Shalf warned the audience.

However, Moore's Law is an economic theory and although it has been underpinned by lithography improvements, there are other ways to improve things, John Shalf stated. He introduced the distinguished panel of speakers who were invited to demystify their respective technology areas to see what the future will bring.

The workshop is covered in full in five articles:

  1. Moore's Law is all about economics but there are alternative technologies on the way
  2. CMOS is still here to stay but we need to think out of the box to reclaim efficiency
  3. Why the hunt for killer applications to run on quantum computers is challenging
  4. SpiNNaker and BrainScaleS neuromorphic systems ready for non-expert use in stochastic inference computing
  5. Beyond Moore's Law panelists address business maturity of new technologies, future developments, neuromorphic chip training, and memristors
