However, the reader should have a basic understanding of I BM data processing. VM/370 (Virtual Machine Facility/370) is a system control program (SCP) that tailors the resources and capabilities of a single System/370 computer to provide concurrent users their one unique (virtual) machine. VM/370 consists of a Control Program (CP), which manages the real computer, a Conversational Monitor System (CMS), which is a general-purpose conversational time-sharing system that executes in a virtual machine, a Remote Spooling Communications Subsystem (RSCS), which spools files to and from geographically remote locations, and a Interactive Problem Control System (I PCS), which provides problem analysis and management faci I ities. The first section of the publication is an introduction; it describes what VM/370 can do. The second, third, fourth, and fifth sections describe the Control Program, Conversational Monitor System, Remote Spooling Communications Subsystem, and Interactive Problem Control System respectively. The appendixes include information about VM/370 publication-to-audience relationship and VM/370-related publications for CMS users. , This publication is a prerequisite for the VM/370 system library. --...- --- ---.-- ------- ------ --..- --------- -~-y- Page of GC20-1800-9 As Updated Aug 1, 1979 by TNL GN25-0U89 ~b Edition (Karch 1919) This edition (GC20-1800-~ together with Technical Newsletter GN25-0489. dated August 1, 1919, applies to Release 6 PLC 4 (Program Level Change) of IBM Virtual Machine Facility/310 and to all subsequent releases until otherwise indicated in new editions or Technical Newsletters.

    DOCUMENT REsUME ED 057 828 LI 003 325 AUTHOR Parker, Edwin B. TITLE SPIRES (Stanford Public Information Retrieval System) 1970-71 Annual Report INSTITUTION Stanford Univ. , Calif. Inst. for Communication Research. SPONS AGENCY National Science Foundation, Washington, D.C. Office of Science Information Services. PUB DATE Dec 71 NOTE 154p.;(23 References) EDRS PRICE MF-$0.65 HC-$6.58 DESCRIPTORS *Computer Programs; *Information Retrieval; *Information Storage; *Information Systems; *On Line Systems IDENTIFIERS Computer Software; SPIRES; *Stanford Public Information Retrieval System ABSTRACT SPIRES (Stanford Public Information REtrieval System) is a computer information storage and retrieval system being developed at Stanford University with funding from the National Science Foundation. SPIRES has two major goals: to provide a user-oriented, interactive, on-line retrieval syste for a variety of researchers at Stanford; and to support the automation efforts of the university libraries by developing and implementing common software. SPIRES I, a prototype system, was implemented at the Stanford Linear Accelerator Center (SLAC) in 1969, from a design based on a 1967 information study involving physicists at SLAC. Its primary data base is a high-energy-physics preprints file. Evaluation of SPIRES I resulted in the definition of a production information storage and retrieval system, SPIRES II. This system will be available -daily, beginning in mid-1972, to faculty, staff, and students of the University.- It is characterized by flexibility, simplicity, and economy. _SPIRES II will operate on-line on an IBM 360/67 computer. This report summarizes the uses of the SPIRES I system over the past year and describes both the nature of SPIRES II and this system,s development over the past year.

Madnick Project Supervisor ABSTRACT In the 1972 the Center for Information Systems Research (CISR), in association with the MIT Information Processing Center (IPC), became one of four study sites participating in the IBM Data Security Study. CISR's primary area of investigation was user requirements for security. The study was completed in early 1974 and the findings of all of the study sites were published as a series of reports from IBM (G320-1370 through G320-1376) in June 1974. CISR faculty and staff contributed nine of the twelve papers which constitute "Volume 4, Study Results: Massachusetts Institute of Technology (G320-1374)." Seven of these papers are reproduced in this report.

The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau consists of the Institute for Basic Standards, the Institute for Materials Research, the Institute for Applied Technology, the Institute for Computer Sciences and Technology, and the Office for Information Programs. THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the United States of a complete and consistent system of physical measurement; coordinates that system with measurement systems of other nations; and furnishes essential services leading to accurate and uniform physical measurements throughout the Nation's scientific community, industry, and commerce. The Institute consists of a Center for Radiation Research, an Office of Meas- urement Services and the following divisions: Applied Mathematics — Electricity — Mechanics — Heat — Optical Physics — Nuclear Sciences" — Applied Radiation " — Quantum Electronics '' — Electromagnetics" — Time " and Frequency — Laboratory Astrophysics " — Cryogenics THE INSTITUTE FOR MATERIALS RESEARCH conducts materials research leading to improved methods of measurement, standards, and data on the properties of well-characterized materials needed by industry, commerce, educational institutions, and Government; provides advisory and research services to other Government agencies; and develops, produces, and distributes standard reference materials.
