Cambrian Explosion of Computing and Big Data in the Post-Moore Era

Author: Satoshi Matsuoka


The so-called “Moore’s Law”, by which the performance of the processors will increase exponentially by factor of 4 every 3 years or so, is slated to be ending in 10-15 year timeframe due to the lithography of VLSIs reaching its limits around that time, and combined with other physical factors. We are now embarking on a project to revolutionize the total system architectural stack in a holistic fashion in the Post-Moore era, from devices and hardware, abstracted by system software and programming models and languages, and optimized according to the device characteristics with new algorithms and applications that exploit them. Such systems will have multitudes of varieties according to the matching characteristics of applications to the underlying architecture, leading to what can be metaphorically described as Cambrian Explosion of computing systems. The diverse elements of such systems will be interconnected with next-generation terabit optics and networks, allowing metropolitan-scale computing infrastructure that would truly realize high performance parallel and distributed computing. However, which algorithms and applications would benefit the most from such future computing, given that some physical constants, e.g., communication latency, cannot be improved? We speculate on some of the scenarios that would change the nature of current Cloud-centric infrastructures towards the Post-Moore era.


Satoshi Matsuoka from April 2018 has become the director of Riken CCS, the top-tier HPC center that represents HPC in Japan, currently hosting the K Computer and developing the next generation Post-K machine, along with multitudes of ongoing cutting edge HPC research being conducted. He had been a Full Professor at the Global Scientific Information and Computing Center (GSIC), a Japanese national supercomputing center hosted by the Tokyo Institute of Technology since 2000, and since 2016 a Fellow at the AI Research Center (AIRC), AIST, the largest national lab in Japan, as well as becoming the head of the joint Lab RWBC-OIL (Open Innovation Lab on Real World Big Data Computing) between the two institutions, in 2017. He was the leader of the TSUBAME series of supercomputers, and has won the 2014 IEEE-CS Sidney Fernbach Memorial Award, the highest prestige in the field of HPC. He still has an appointment as a Professor at the Department of Mathematical and Computing Sciences, Tokyo Institute of Technology, to continue his research activities spanning the three institutions in HPC and scalable Big Data & AI.

Reproducibility in Computational and Data-enabled Science

Author: Victoria Stodden


As computation becomes central to scientific research and discovery new questions arise regarding the implementation, dissemination, and evaluation of methods that underlie scientific claims. I present a framework for conceptualizing the affordances that support scientific inference including computational reproducibility, transparency, and generalizability of findings. For example, reproducibility in computational research can be interpreted most narrowly as a simple trace of computational steps that generate scientific findings, and most expansively as an entirely independent implementation of an experiment that tests the same hypothesis as previously published work. Standards for determining a scientific finding are necessarily adapting to computationally- and data-enabled research. Finally, the social context for these innovations raises important questions regarding incentives to engage in new research practices and the ethics of these practices themselves.
