Lynn Conway Professor of Electrical Engineering and Computer Science, Emerita University of Michigan, Ann Arbor, MI 48109-2110 [email protected]
IBM-ACS: Reminiscences and Lessons Learned From a 1960’s Supercomputer Project * Lynn Conway Professor of Electrical Engineering and Computer Science, Emerita University of Michigan, Ann Arbor, MI 48109-2110 [email protected] Abstract. This paper contains reminiscences of my work as a young engineer at IBM- Advanced Computing Systems. I met my colleague Brian Randell during a particularly exciting time there – a time that shaped our later careers in very interesting ways. This paper reflects on those long-ago experiences and the many lessons learned back then. I’m hoping that other ACS veterans will share their memories with us too, and that together we can build ever-clearer images of those heady days. Keywords: IBM, Advanced Computing Systems, supercomputer, computer architecture, system design, project dynamics, design process design, multi-level simulation, superscalar, instruction level parallelism, multiple out-of-order dynamic instruction scheduling, Xerox Palo Alto Research Center, VLSI design. 1 Introduction I was hired by IBM Research right out of graduate school, and soon joined what would become the IBM Advanced Computing Systems project just as it was forming in 1965. In these reflections, I’d like to share glimpses of that amazing project from my perspective as a young impressionable engineer at the time. It was a golden era in computer research, a time when fundamental breakthroughs were being made across a wide front. The well-distilled and highly codified results of that and subsequent work, as contained in today’s modern textbooks, give no clue as to how they came to be. Lost in those texts is all the excitement, the challenge, the confusion, the camaraderie, the chaos and the fun – the feeling of what it was really like to be there – at that frontier, at that time. -
13347 CICS Introduction and Overview
CICS Introduction and Overview Ezriel Gross Circle Software Incorporated August 13th, 2013 (Tue) 4:30pm – 5:30pm Session 13347 Agenda What is CICS and Who Uses It Pseudo Conversational Programming CICS Application Services CICS Connectivity CICS Resource Definitions CICS Supplied Transactions CICS Web Services CICS The Product What is CICS? CICS is an online transaction processing system. Middleware between the operating system and business applications. Manages the user interface. Retrieves and modifies data. Handles the communication. CICS Customers Banks Mortgage Account Reconciliations Payroll Brokerage Houses Stock Trading Trade Clearing Human Resources Insurance Companies Policy Administration Accounts Receivables Claims Processing Batch Versus Online Programs The two ways to process input are batch and online. Batch requests are saved then processed sequentially. After all requests are processed the results are transmitted. Used for order entry processing such as warehouse applications. Online requests are received randomly and processed immediately. Results are transmitted as soon as they are available. Response time tends to be sub-second. Used for applications – such as: Credit Card Authorization. Transaction Processing Requirements Large volume of business transactions to be rapidly and accurately processed Multiple users, single/sysplex or distributed With potentially: – A huge number of users – Simultaneous access to data – A large volume of data residing in multiple database types – Intense security and data integrity controls necessary The access to the data is such that: – Each user has the perception of being the sole user of the system – A set of changes is guaranteed to be logically consistent. If a failure occurs, any intermediate results are undone before the system becomes available again – A completed set of changes is immediately visible to other users A Business Transaction A transaction has a 4-character id.
