John P. Hayes, the Claude E. Shannon Professor of Engineering Science, will retire from the EECS faculty on May 31, 2023, after 41 years at the University of Michigan. His career has been marked by explorations into the performance and reliability of computer architecture and computing systems, including computer aided design and testing, fault-tolerant design, and emerging computing technologies such as quantum computing and stochastic computing.
At university, John flourished as he immersed himself into the study of electrical engineering; this was reflected in his receipt of Class Prizes in 1963, 1964, and 1965. He completed internships during the summers which introduced him to the world of industry and practice of engineering. In 1962, he worked at Radio-Telefs ireann, the Irish Radio-Television Network in Dublin, Ireland. In 1963, he worked for Stadtwerke Bremen, a municipal electric power company in Bremen, Germany. And in 1964, he interned at Elin-Union, a manufacturer of electrical equipment in Vienna, Austria.
In terms of graduate study in computers, there were no options in Ireland, and only one or two in England; most programs were in the United States. John was fortunate enough to be admitted and get a research assistantship at the University of Illinois, where he worked in the Digital Computer Laboratory on a computer design and building project called ILLIAC III, a fine-grained SIMD (single instruction, multiple data) parallel processing pattern recognition computer. John spent two years in this group, where he was responsible for the logic design of the input-output channel control units of ILLIAC III.
For the final two years of his PhD study , John worked as a Research Assistant with the Switching Systems Group of the Coordinated Science Laboratory, where he carried out research on digital circuit testing, and for his PhD thesis he focused on digital design, logic design, and testing. This work set the course for research interests for many years to come.
In 1985, as the EECS Department was formed, John founded the Advanced Computer Architecture Laboratory, which exists today as the Computer Engineering Laboratory and is dedicated to creating a community around architectural innovation at Michigan. In the years after the merger, the EECS department evolved organizationally from three groups to two divisions, CSE and ECE. Although he had a joint appointment in these two units for a while, John ultimately concluded that his allegiance was to CSE.
Over the course of his career, John has made significant contributions to digital testing techniques and to switching theory and logical design. He has authored over 340 technical papers, several patents, and seven books including Computer Architecture and Organization, (McGraw-Hill, 3rd ed. 1998), Quantum Circuit Simulation (Springer, 2009), and Design, Analysis and Test of Logic Circuits under Uncertainty (Springer, 2012). He has advised 37 Ph.D. students.
Logan's practice primarily focuses on the preparation and prosecution of patent applications before the U.S. Patent and Trademark Office. He has extensive experience in drafting and prosecuting applications relating to the electrical and mechanical arts, computer software, computer hardware, computer architecture, telecommunications, mobile communications, voice processing, business methods, data encryption/decryption, data storage, and networking. He has handled sensitive and secret projects related intellectual property for several major clients. He also has experience in litigation and inter partes review.
John Patrick Hayes is an Irish-American computer scientist and electrical engineer, the Claude E. Shannon Chair of Engineering Science at the University of Michigan.[1] He supervised over 35 doctoral students, coauthored seven books and over 340 peer-reviewed publications.[2] His Erds number is 2.
Hayes has written extensively on the use of hypercube graphs in supercomputing,[5][6][7]He has also written highly cited research papers on fault-tolerant design,[8] reversible computing,[9] and stochastic computing.[10]
Hayes became an IEEE Fellow in 1985 "for contributions to digital testing techniques and to switching theory and logical design",[11] and an ACM Fellow in 2001 "for outstanding contributions to logic design and testing and to fault-tolerant computer architecture."[12] In 2004, the University of Illinois Urbana-Champaign department of electrical and computer engineering gave him their distinguished alumni award.[4]
The Greek Myths tell of creatures plucked from the surface of the Earth and enshrined as constellations in the night sky. Something similar is happening today in the world of computing. Data and programs are being swept up from desktop PCs and corporate server rooms and installed in "the compute cloud."
The shift from locally installed programs to cloud computing is just getting under way in earnest. Shrink-wrap software still dominates the market and is not about to disappear, but the focus of innovation indeed seems to be ascending into the clouds. Some substantial fraction of computing activity is migrating away from the desktop and the corporate server room. The change will affect all levels of the computational ecosystem, from casual user to software developer, IT manager, even hardware manufacturer.
When personal computers arrived in the 1980s, part of their appeal was the promise of "liberating" programs and data from the central computing center. (Ted Nelson, the prophet of hypertext, published a book titled Computer Lib/Dream Machines in 1974.) Individuals were free to control their own computing environment, choosing software to suit their needs and customizing systems to their tastes.
But PCs in isolation had an obvious weakness: In many cases the sneaker-net was the primary means of collaboration and sharing. The client-server model introduced in the 1980s offered a central repository for shared data while personal computers and workstations replaced terminals, allowing individuals to run programs locally.
In the current trend, the locus of computation is shifting again, with functions migrating outward to distant data centers reached through the Internet. The new regime is not quite a return to the hub-and-spoke topology of time-sharing systems, if only because there is no hub. A client computer on the Internet can communicate with many servers at the same time, some of which may also be exchanging information among themselves. However, even if we are not returning to the architecture of time-sharing systems, the sudden stylishness of the cloud paradigm marks the reversal of a long-standing trend. Where end users and corporate IT managers once squabbled over possession of computing resources, both sides are now willing to surrender a large measure of control to third-party service providers. What brought about this change in attitude?
For the individual, total control comes at a price. Software must be installed and configured, then updated with each new release. The computational infrastructure of operating systems and low-level utilities must be maintained. Every update to the operating system sets off a cascade of subsequent revisions to other programs. Outsourcing computation to an Internet service eliminates nearly all these concerns. Cloud computing also offers end users advantages in terms of mobility and collaboration.
Although the new model of Internet computing has neither hub nor spokes, it still has a core and a fringe. The aim is to concentrate computation and storage in the core, where highperformance machines are linked by high-bandwidth connections, and all of these resources are carefully managed. At the fringe are the end users making the requests that initiate computations and who receive the results.
Wordstar for the Web. The kinds of productivity applications that first attracted people to personal computers 30 years ago are now appearing as software services. The Google Docs programs are an example, including a word processor, a spreadsheet, and a tool for creating PowerPoint-like presentations. Another undertaking of this kind is Buzzword, a Web-based word processor acquired by Adobe Systems in 2007. Another recent Adobe product is Photoshop Express, which has turned the well-known image-manipulation program into an online service.
A major challenge of moving applications to the cloud is the need to master multiple languages and operating environments. In many cloud applications a back-end process relies on a relational database, so part of the code is written in SQL or other query language. On the client side, program logic is likely to be implemented in JavaScript embedded within HTML documents. Standing between the database and the client is a server application that might be written in a scripting language (such as PHP, Java, and Python). Information exchanged between the various layers is likely to be encoded in some variation of XML.
Even though the new model of remote computing seems to reverse the 1980s "liberation" movement that gave individual users custody over programs and data, the shift does not necessarily restore control to managers in the corporate IT department.
What are the most important IT challenges for the next 25 years? At the recent Gartner Emerging Trends Symposium/ITxpo, Gartner analysts identified seven IT grand challenges that, if met, will have profound economic, scientific and societal impacts. They are:
"IT leaders should always be looking ahead for the emerging technologies that will have a dramatic impact on their business, and information on many of these future innovations are already in some public domain," says Gartner VP Ken McGee. To find such information, Gartner suggests examining relevant research papers, patents, and production prototypes.
