Summaries of the FY 1981 applied mathematical sciences research program

Description: Applied Mathematical Sciences serves as the DOE focal point for monitoring and advancing the state of the art in mathematics, statistics, and computer science. Several DOE mission programs develop and refine specific techniques from the applied mathematical sciences applicable to their immediate needs. In contrast, Applied Mathematical Sciences concentrates on more broadly based, continuing needs throughout the DOE community. Emphasis is placed on research basic to the analysis, development, and use of large-scale computational models; the management and analysis of large, complex collections of information; and the effective use of DOE computing resources. The purpose of this research is not to improve existing technologies and methodologies, but rather to render them obsolete. Each part of the Applied Mathematical Sciences activity has been designed with the help and advice of leading mathematicians and computer scientists from universities, industry, and DOE laboratories to assure the broadest and greatest impact on the nation's energy R and D enterprise. Many of them are expert in industry's needs in the relevant areas. Close liaison is maintained with other federal agencies in the selection of areas of emphasis and of individual research tasks. This is high leverage research. In favorable cases, the results may be of great benefit simultaneously to a number of different energy technologies. The requested increase will be an exceptionally sound investment.

General-purpose computer networks and resource sharing in ERDA. Volume 3. Remote resource-sharing experience and findings

Description: The investigation focused on heterogeneous networks in which a variety of dissimilar computers and operating systems were interconnected nationwide. Homogeneous networks, such as MFE net and SACNET, were not considered since they could not be used for general purpose resource sharing. Issues of privacy and security are of concern in any network activity. However, consideration of privacy and security of sensitive data arise to a much lesser degree in unclassified scientific research than in areas involving personal or proprietary information. Therefore, the existing mechanisms at individual sites for protecting sensitive data were relied on, and no new protection mechanisms to prevent infringement of privacy and security were attempted. Further development of ERDA networking will need to incorporate additional mechanisms to prevent infringement of privacy. The investigation itself furnishes an excellent example of computational resource sharing through a heterogeneous network. More than twenty persons, representing seven ERDA computing sites, made extensive use of both ERDA and non-ERDA computers in coordinating, compiling, and formatting the data which constitute the bulk of this report. Volume 3 analyzes the benefits and barriers encountered in actual resource sharing experience, and provides case histories of typical applications.

Computer technology forecasting at the National Laboratories

Description: The DOE Office of ADP Management organized a group of scientists and computer professionals, mostly from their own national laboratories, to prepare an annually updated technology forecast to accompany the Department's five-year ADP Plan. The activities of the task force were originally reported in an informal presentation made at the ACM Conference in 1978. This presentation represents an update of that report. It also deals with the process of applying the results obtained at a particular computing center, Brookhaven National Laboratory. Computer technology forecasting is a difficult and hazardous endeavor, but it can reap considerable advantage. The forecast performed on an industry-wide basis can be applied to the particular needs of a given installation, and thus give installation managers considerable guidance in planning. A beneficial side effect of this process is that it forces installation managers, who might otherwise tend to preoccupy themselves with immediate problems, to focus on longer term goals and means to their ends.

Traditional computing center as a modern network node

Description: There is an obvious trend toward decentralization of computing power from the traditional, large computing center. Even so there remains a generous, but changing role for such centers to play. Their capabilities would then be complimentary to smaller, individualized facilities, so the user would benefit greatly from a general purpose, local network on which the large center represented a node. There is no network currently available that exhibits all the attributes of the ideal local for this environment. It can be approached, however, by combining several diverse products as network segments, which are interconnected via processor gateways. This is in fact the strategy being followed at Brookhaven National Laboratory, which has a computing environment typical of a large class of institutions. The attributes of the ideal network are presented. A brief discussion of the current state-of-the-art in networking is then given. Finally, the particulars of the Brookhaven implementation are offered as a case history.

Data telecommunications at the CSCF

Description: At Brookhaven National Laboratory data telecommunication for remote job entry, interactive time sharing, networking, graphics, and special purpose links became increasingly important--they now rival the more traditional over-the-counter traffic. The BNL Central Scientific Computing Facility (CSCF) responded to this need with a number of developments. The latest and most comprehensive of these is a ''front-end'' communications system built around MODCOMP II computers. To put this project into its proper framework, some historical background is presented describing predecessor systems, the development of specifications, and the factors considered in the decision to turn to MODCOMP. The hardware is based around dual MODCOMP II-233 processors with a specially developed link to the larger CSCF machines, two Control Data 6600 computers and one CDC 7600. The MODCOMP software is based upon an existing system developed by Chrysler Corporation, running under MAXCOM. On the Control Data side Scope 3.4/INTERCOM 4 is used as a basis. The developments and modifications, both hardware and software, necessary for these components to meet Brookhaven's specifications are described. Certain related special-purpose data link applications are described. Among them are a research project in national resource sharing networks using ARPANET, and a connection to the National Weather Service machines in Suitland, Maryland, using the bit-oriented protocol ADCCP. Future goals are briefly presented. 2 figures.

Department of Energy research in utilization of high-performance computers

Description: Department of Energy (DOE) and other Government research laboratories depend on high-performance computer systems to accomplish their programmatic goals. As the most powerful computer systems become available, they are acquired by these laboratories so that advances can be made in their disciplines. These advances are often the result of added sophistication to numerical models, the execution of which is made possible by high-performance computer systems. However, high-performance computer systems have become increasingly complex, and consequently it has become increasingly difficult to realize their potential performance. The result is a need for research on issues related to the utilization of these systems. This report gives a brief description of high-performance computers, and then addresses the use of and future needs for high-performance computers within DOE, the growing complexity of applications within DOE, and areas of high-performance computer systems warranting research. 1 figure.

Saturday Academay of Computing and Mathematics (SACAM) at the Oak Ridge National Laboratory

Description: To be part of the impending Information Age, our students and teachers must be trained in the use of computers, logic, and mathematics. The Saturday Academy of Computing and Mathematics (SACAM) represents one facet of Oak Ridge National Laboratory's (ORNL) response to meet the challenge. SACAM attempts to provide the area's best high school students with a creative program that illustrates how researchers are using computing and mathematics tools to help solve nationally recognized problems in virtually all scientific fields. Each SACAM program is designed as eight 3-hour sessions. Each session outlines a current scientific question or research area. Sessions are presented on a Saturday morning by a speaker team of two to four ORNL scientists (mentors) working in that particular field. Approximately four students and one teacher from each of ten area high schools attend the eight sessions. Session topics cover diverse problems such as climate modeling cryptography and cryptology, high-energy physics, human genome sequencing, and even the use of probability in locating people lost in a national forest. Evaluations from students, teachers, and speakers indicate that the program has been well received, and a tracking program is being undertaken to determine long-range benefits. An analysis of the program's successes and lessons learned is presented as well as resources required for the program.

Graphic artist in computerland

Description: The field of computer graphics is rapidly opening up to the graphic artist. It is not necessary to be a programming expert to enter this fascinating world. The capabilities of the medium are astounding: neon and metallic effects, translucent plastic and clear glass effects, sensitive 3-D shadings, limitless textures, and above all color. As with any medium, computer graphics has its advantages, such as speed, ease of form manipulation, and a variety of type fonts and alphabets. It also has its limitations, such as data input time, final output turnaround time, and not necessarily being the right medium for the job at hand. And finally, it is the time- and cost-saving characteristics of computer-generated visuals, opposed to original artwork, that make computer graphics a viable alternative. This paper focuses on parts of the computer graphics system in use at the Los Alamos National Laboratory to provide specific examples.

Delta-t protocol specification: working draft

Description: This document is one of a series describing protocols associated with the Livermore Interactive Network Communication System (LINCS) hierarchical architecture. At the heart of LINCS is its basic interprocess communication (LINCS-IPC) service. LINCS-IPC defines a reliable, flow controlled, full duplex, uninterpreted, labeled bit stream communication service. LINCS-IPC is level 4 in the LINCS architecture. Level 3 of LINCS is the Network layer defining an internetwork datagram type service. LINCS-IPC interfaces to User processes that utilize higher level syntactic and semantic conventions for process interaction. The transport service provided by the Delta-t protocol can be considered a sublayer of the LINCS-IPC layer. Delta-t augments the Network level service as required to support LINCS-IPC. This document specifies the services provided by the Delta-t protocol to support LINCS-IPC, the operation of Delta-t, and the services Delta-t requires of the Network level. This document was written to be self-contained but the reader will find it useful to have available for reference the LINCS-IPC and LINCS DeltaGram Network layer protocol specifications. Implementations are underway in Pascal for the PDP-11 running under RT11 and RX11, in BLISS for the VAX running under VMS, in MODEL for the CRAY-1 and CDC 7600 running under NLTSS and LTSS, and for the SEL 32/75 running under PORT.

DOE's Computer Incident Advisory Capability (CIAC)

Description: Computer security is essential in maintaining quality in the computing environment. Computer security incidents, however, are becoming more sophisticated. The DOE Computer Incident Advisory Capability (CIAC) team was formed primarily to assist DOE sites in responding to computer security incidents. Among CIAC's other responsibilities are gathering and distributing information to DOE sites, providing training workshops, coordinating with other agencies, response teams, and vendors, creating guidelines for incident handling, and developing software tools. CIAC has already provided considerable assistance to DOE sites faced with virus infections and worm and hacker attacks, has issued over 40 information bulletins, and has developed and presented a workshop on incident handling. CIAC's experience in helping sites has produced several lessons learned, including the need to follow effective procedures to avoid virus infections in small systems and the need for sound password management and system administration in networked systems. CIAC's activity and scope will expand in the future. 4 refs.
