Hill and Ravi Rajwar Computer Sciences Dept. University of Wisconsin-Madison {markhill,rajwar}@cs.wisc.edu Filed at http://www.cs.wisc.edu/~markhill/mp2001.html 29 March 2001 Several researchers have anecdotally noted that the number of multiprocessor papers appears to be in decline (despite industry's continued interest in the subject). To examine this hypothesis we placed papers from the first 28 ISCA (1973-2001) into categories. Any selection of and assignment to categories is somewhat subjective and error-prone. We attempted to be generous to the multiprocessor category. For ISCA 2001, for example, we included a paper on compiler/verification techniques ("A Simple Method for Automatically Extracting Formal Specifications from FLASH Cache Coherence Protocol Code") and another on a parallel implementation of the sequential programming model ("Removing Architectural Bottlenecks to the Scalability of Speculative Parallelization"). Additional categories were dataflow, fault tolerance, interconnection networks, and other. Below we present ISCA multiprocessor paper data in histogram form and then give tabular data for all categories. We find that: * Multiprocessor papers have averaged 30% of the total ISCA papers. * To first order, the number of multiprocessor papers expanded from the 1975 to 1985 and then declined thereafter. * The total number of papers follows a similar but less dramatic trend. As a research community, we should reflect on whether such trends are deliberate and appropriate or the result of unintended consequences. Several researchers predict an inflection point in multiprocessing due to the the ubiquitous parallelism offered by multithreading and chip multiprocessing. Perhaps we need to expand the "normal science" needed to accelerate this inflection point [c.f., Thomas S. Kuhn, The Structure of Scientific Revolutions, University of Chicago Press, Chicago, 1962]. ---------------------------------- Histogram for Absolute Number of Papers: http://www.cs.wisc.edu/~markhill/mp2001-absolute.gif ---------------------------------- Histogram for Relative Percent: http://www.cs.wisc.edu/~markhill/mp2001-relative.gif ---------------------------------- Total MP ISCA# Year Papers Papers Histogram 1 1973 28 5 (17%) ***** 2 1974 38 2 ( 5%) ** - 1975 -- No ISCA -- 3 1976 40 8 (20%) ******** 4 1977 27 10 (37%) ********** 5 1978 38 7 (18%) ******* 6 1979 27 6 (22%) ****** 7 1980 40 11 (28%) *********** 8 1981 41 15 (37%) *************** 9 1982 35 9 (26%) ********* 10 1983 54 19 (35%) ******************* 11 1984 46 16 (35%) **************** 12 1985 51 25 (49%) ************************* 13 1986 50 19 (38%) ******************* 14 1987 35 10 (29%) ********** 15 1988 50 21 (42%) ********************* 16 1989 46 14 (30%) ************** 17 1990 34 15 (44%) *************** 18 1991 38 12 (32%) ************ 19 1992 39 14 (36%) ************** 20 1993 32 15 (47%) *************** 21 1994 34 12 (35%) ************ 22 1995 37 13 (35%) ************* 23 1996 28 11 (39%) *********** 24 1997 30 8 (27%) ******** 25 1998 33 7 (21%) ******* 26 1999 26 5 (19%) ***** 27 2000 29 3 (10%) *** 28 2001 24 2 ( 8%) ** ---------------------------------- Categories: There are roughly 5 categories: 1. Others: everything not in the remaining categories. Also included in this category are uniprocessor memory systems, I/O and disk subsystems, programming languages, and special/general purpose uniprocessor architectures (eg. superscalar, multiscalar, and SMT processors). 2. Multiprocessors (MP): anything to do with multiple processors and a shared-memory, message passing or some other parallel programming model. Thus array processors and such also find themselves in this category. We have also counted the 2000 and 2001 papers on "speculative parallelization of sequential code and running it on a shared-memory system" in this category, although strictly speaking they should be in the "Others" category similar to the Multiscalar and other such paradigms. 3.

Hill <markhill@cs.wisc.edu> ---------------------------------------------------------------------- STUDENT TRAVEL GRANTS FOR ISCA 2001 SIGARCH is providing funds for a limited number of travel grants for student members of SIGARCH to attend ISCA 2001. Grants can cover transportation, symposium registration, and lodging, but not meals. The application deadline is APRIL 20, 2001 and recipients will be notified approximately one week later. The size of grants may be limited due to budgetary constraints. In particular there may be upper bounds on specific items, and we may set different upper bounds based upon the level of involvement (symposium speaker, vs. workshop speaker, vs. coauthor for example). Grants will be paid on submission of original travel receipts and a brief trip report. Grant application forms are available at http://www.ee.princeton.edu/~isca2001.

The goal of this new workshop is to provide a forum for researchers and practitioners from industry and academia to discuss advances in technology, architecture, and algorithms that address the need for scalability in multiprocessors and the growing gap between CPU/network and memory speeds. Both hardware and software approaches to addressing scalability and speed disparities are encouraged. We are especially interested in attracting new, experimental or paper techniques, technologies and algorithms that address these issues. Submissions: Please submit a 10 page extended abstract for review by the program committee. Authors of accepted abstracts will have an opportunity to present a 30-minute talk on their work. We hope to encourage presentations of work in early stages of development. A workshop post-proceedings in the form of a book will help to document the research presented. An informal proceedings containing all papers will be provided to all attendees. Possible topics for talks include, but are not limited to: * Scalable cache coherence * Processors in memory * Novel RAM architectures * RAM technology issues * Reconfigurable memory systems * Intelligent disks * Bus/interconnect architectures * Network memory * Off-chip interconnect design * Compilation techniques * Real-time memory compression * Operating system memory management * Hardware and software fault tolerance of memory systems * Multiprocessing on a single device (chip) * Scalable memory access using a network of workstations * Software cache coherence * Virtual memory systems Keynote speaker * 2 keynotes will be invited Program Committee * TBD Submissions: Please send your 10 page extended abstract in ps or pdf to either of the workshop co-chairs by April 13, 2001.

Storage density has increased at 100% per year for the past three years (60% per year for the past 30 years), but this is barely enough to keep up with the storage demands of the modern economy. Digital media and electronic commerce stretch storage system design with problems not encountered a few years ago. FAST brings together the top storage systems researchers and practitioners, providing a premier forum for discussing the design, implementation, and uses of storage systems. It aims to bring together the best work in file and storage systems in one venue. The large number of file systems papers presented at all operating system conferences shows that there is no shortage of research in this area. FAST will be the successor to IOPADS, which for several years was the top conference dedicated to parallel and distributed IO systems. The conference will consist of two days of technical presentations, including refereed papers, invited talks, and an introductory keynote address. A session of work-in-progress presentations is planned, and informal Birds-of-a-Feather sessions may be organized by attendees. Refereed papers will be published in the Proceedings, provided free to technical session attendees, and available for purchase from USENIX. The FAST 2002 Program Committee invites you to contribute your ideas, proposals and papers for tutorials, invited talks program, refereed papers track, workshops, work-in-progress reports, and symposia tracks. We welcome submissions that address any and all issues relating to File and Storage Systems. The Call for Papers with submission guidelines and suggested topics is now available at: http://www.usenix.org/events/fast/cfp/ Submissions are due July 13, 2001. We look forward to seeing you in Monterey in January 2002!
