Abstract: For the last three years, a team of us at MIT, Stanford, CMU, Google and VMware have built a new operating system stack, based on a high-performance distributed DBMS. In other words, all OS state (files, messages, scheduling information, etc.) is stored in the DBMS and all OS services are written in SQL plus stored procedures. At the present time, we have a secured venture capital funding and are about to release a commercial open source version. In this talk, I report on aspects of our system, including: Performance: DBOS is competitive with the state of the art concerning file system performance, message performance and scheduling performance. All of these are implemented in SQL. Provenance: Because all OS state is in DBMS tables, DBOS change capture moves all state to a warehouse DBMS (currently Vertica or Redshift) with a runtime overhead of about 5%. In this case, security queries (e.g. looking for outliers) supporting the “right to be forgotten” in GDPR-style systems and other provenance operations can be coded in SQL. Experiments with a current security product show that DBOS can both capture provenance data and query it with higher performance. Serverless environment: We have written a Java serverless environment on top of DBOS. It is an order of magnitude faster than current systems (AWS Lambda, Open Whisk) because it co-locates computation and data whenever possible. Also, provenance facilitates a novel time-travel debugger. Early enterprise usage: I will report on early DBOS usage in enterprise environments at three large enterprises. Commercialization changes to DBOS: These include moving to TypeScript and open source DBMSs. Bio: Dr. Stonebraker has been a pioneer of data base research and technology for more than forty years. He was the main architect of the INGRES relational DBMS, and the object-relational DBMS, POSTGRES. These prototypes were developed at the University of California at Berkeley where Stonebraker was a Professor of Computer Science for twenty-five years. More recently at M.I.T. he was the co-architect of the C-Store column- oriented DBMS, the H-Store transaction processing engine, the Data Tamer data integration system, the SciDB array processing engine, the Kyrix visualization system and the operating system DBOS. He is the founder of ten venture-capital backed startups which have commercialized his prototypes. Professor Stonebraker is the author of scores of research papers on data base technology, operating systems and the architecture of system software services. He was awarded the ACM System Software Award in 1992, for his work on INGRES. Additionally, he was awarded the first annual Innovation award by the ACM SIGMOD special interest group in 1994 and was elected to the National Academy of Engineering in 1997. He was awarded the IEEE John Von Neumann award in 2005, and the ACM Turing Award in 2014. Presently he is an Adjunct Professor of Computer Science at M.I.T., where he is working on a variety of future-generation data-oriented projects. This joint meeting of the Boston Chapter of the IEEE Computer Society and GBC/ACM will be hybrid (in person and online), part of getting back to normal after the COVID-19 lockdown.

For instance, our systems for dealing with pandemics, climate change, and financial stress have been less than completely successful, in significant part because of unanticipated human behaviors. This talk will cover new approaches to engineering ecosystems that better integrate human behavior and discuss how new technologies like Large Language Models (LLMs) can help.Bio:Professor Alex 'Sandy' Pentland directs MIT Connection Science, an MIT-wide initiative, and previously helped create and direct the MIT Media Lab and the Media Lab Asia in India. He is one of the most-cited computational scientists in the world. Forbes declared him one of the "7 most powerful data scientists in the world" along with Google founders and the Chief Technical Officer of the United States. He is on the Board of the UN Foundations' Global Partnership for Sustainable Development Data, co-led the World Economic Forum discussion in Davos that led to the EU privacy regulation GDPR, and was one of the UN Secretary General's "Data Revolutionaries" helping to forge the transparency and accountability mechanisms in the UN's Sustainable Development Goals. He has received numerous awards and prizes such as the McKinsey Award from Harvard Business Review, the 40th Anniversary of the Internet from DARPA, and the Brandeis Award for work in privacy. Recent invited keynotes include annual meetings of OECD, G20, World Bank, and JP Morgan.He is a member of advisory boards for the UN Secretary General, the UN Foundation, Consumers Union, and OECD, and formerly the American Bar Association, Google, AT&T, and Nissan. He is a member of the U.S. National Academy of Engineering and council member within the World Economic Forum.Over the years Sandy has advised more than 80 PhD students. Together Sandy and his students have pioneered computational social science, organizational engineering, wearable computing (Google Glass), image understanding, and modern biometrics. His most recent books are Building the New Economy and Trusted Data, both published by MIT Press, Social Physics, published by Penguin Press, and Honest Signals, published by MIT Press.This meeting of the Boston Chapter of the IEEE Computer Society will be hybrid (in person and online), part of getting back to normal after the COVID-19 lockdown.Up-to-date information about this and other talks is available online at https://ewh.ieee.org/r1/boston/computer/.
