Interactive benchmark comparison between a VAX 11/780 and a VAX 11/782

Description: In this paper, we present the results of a benchmark comparison between a single processor VAX 11/780 and a dual processor VAX 11/782. Using the VMS Monitor utility and available accounting data, we first parameterized the workload on the VAX 11/782. We developed synthetic scripts that matched both the current workload parameters and also generated four forecasted workloads. Using a remote terminal emulator (RTE), we submitted interactive user commands from the scripts to the single and dual processor VAXs. Response times were then measured as a function of script category and VAX model.

Evaluation of DEC`s GIGAswitch for distributed parallel computing

Description: One of Sandia`s research efforts is to reduce the end-to-end communication delay in a parallel-distributed computing environment. GIGAswitch is DEC`s implementation of a gigabit local area network based on switched FDDI technology. Using the GIGAswitch, the authors intend to minimize the medium access latency suffered by shared-medium FDDI technology. Experimental results show that the GIGAswitch adds 16.5 microseconds of switching and bridging delay to an end-to-end communication. Although the added latency causes a 1.8% throughput degradation and a 5% line efficiency degradation, the availability of dedicated bandwidth is much more than what is available to a workstation on a shared medium. For example, ten directly connected workstations each would have a dedicated bandwidth of 95 Mbps, but if they were sharing the FDDI bandwidth, each would have 10% of the total bandwidth, i.e., less than 10 Mbps. In addition, they have found that when there is no output port contention, the switch`s aggregate bandwidth will scale up to multiples of its port bandwidth. However, with output port contention, the throughput and latency performance suffered significantly. Their mathematical and simulation models indicate that the GIGAswitch line efficiency could be as low as 63% when there are nine input ports contending for the same output port. The data indicate that the delay introduced by contention at the server workstation is 50 times that introduced by the GIGAswitch. The authors conclude that the GIGAswitch meets the performance requirements of today`s high-end workstations and that the switched FDDI technology provides an alternative that utilizes existing workstation interfaces while increasing the aggregate bandwidth. However, because the speed of workstations is increasing by a factor of 2 every 1.5 years, the switched FDDI technology is only good as an interim solution.

The new SPI: More refined and integrated system checks

Description: Current research and development at Lawrence Livermore National Laboratory will soon provide the system/security administrator a new set of tools ranging from monitors and intrusion detection to sensitive information detectors. However, the full potential of both existing and future tools will not be realized until a complimentary set of utilities has been integrated into a single computer security workbench in which the results from one process can be used as input to another. The Security Profile Inspector (SPI), a UNIX and VMS security profiler, has taken the first step toward providing this integration. This is accomplished by using an interpreted query language which allows specific, general, and even recursive queries of system configuration information. The new SPI is extremely flexible, so that users can easily tailor existing checks for their system or even add new checks. Similarly, other tools can ask specific questions, for example limiting their inquiries to a single user or a list of users which meet certain criteria. Furthermore, the query language was designed to support multiple architectures and operating systems and to ease the transition of tools to new platforms.

The console password feature for DEC workstations

Description: New VAXstations and all DECstations offer a ``hardware`` password feature that, when enabled, restricts unauthorized access to your system console terminal when turned on or restarted. VAXstation 3100s shipped after July, 1989 offer this feature. A description of this feature should be part of the Hardware User Guide for your workstation; however, some of the early systems did not document this security enhancement. This document is based on the author`s investigation as well as information provided by the Digital Equipment Corporation.

MPRINT: VAX printing made simple

Description: Users with stand-alone personal computers and personal printers usually find printing simple, but on a VAX computer or VAX cluster there may be many printers of different types located in different areas. The print queues set up for these printers may require different form qualifiers and may not all be able to print all documents. This article describes the basic steps a VAX system manager should take in setting up and managing print queues on a VAX and tells how to access these queues from a VAX, Unix, Macintosh, or DOS Computer. It gives a basic overview, but includes several helpful items that are obscure or completely undocumented. Following this overview, there is a description of a Fortran program, MPRINT, written to simplify printing for users. The MPRINT program simplifies the choice of printers and print forms for users of VAX print queues by allowing them to select from a one line per queue menu. The menu includes queue descriptions and only lists printers which can correctly print the specified file. MPRINT selects the correct form to use based on file type and maximum record length of the file. MPRINT may be useful at your site, and provides examples of a number of system services. MPRINT includes routines to do a user open of a file and get information from the File and Record Access Blocks (FAB and RAB), and a routine to obtain information about print queues. There are also routines to parse a file name, detab a character buffer, and trim trailing nulls and blanks from a character string.

Computer workstation speeds

Description: This report compares the performance of several computers. Some of the machines are discontinued, and some are anticipated, but most are currently installed at Sandia Laboratories. All the computers are personal workstations or departmental servers, except for comparison, one is a Cray C90 mainframe supercomputer (not owned by the Laboratories). A few of the computers have multiple processors, but parallelism is not tested. The time to run three programs is reported for every computer. Unlike many benchmarks, these are complete application programs. They were written and are used at Sandia Laboratories. Also SPECmarks are reported for many computers. These are industry standard performance ratings. They are in general agreement with the speeds of running the Sandia programs. This report concludes with some background material and notes about specific manufacturers.

Software for device-independent graphical input

Description: A three-level model and a graphics software structure based on the model that was developed with the goal of making graphical applications independent of the input devices are described. The software structure makes graphical applications independent of the input devices in a manner similar to the way the SIGGRAPH CORE proposal makes them independent of the output devices. A second goal was to provide a convenient means for application programmers to specify the user-input language for their applications. The software consists of an input handler and a table-driven parser. The input handler manages a CORE-like event queue, changing input events into terminal symbols and making their terminal symbols available to the parser in a uniform manner. It also removes most device dependencies. The parser is table driven from a Backus-Naur form (BNF) grammer that specifies the user-input language. The lower level grammar rules remove the remaining device dependencies from the input, and the higher level grammar rules specify legal sentences in the user-input language. Implementation of this software is on a table-top minicomputer. Experience with retrofitting existing applications indicates that one can find a grammar that removes essentially all the device dependencies from the application proper.

Remote procedure execution software for distributed systems

Description: Remote Procedure Execution facilitates the construction of distributed software systems, spanning computers of various types. Programmers who use the RPX package specify subroutine calls which are to be executed on a remote computer. RPX is used to generate code for dummy routines which transmit input parameters and receive output parameters, as well as a main program which receives procedure call requests, calls the requested procedure, and returns the result. The package automatically performs datatype conversions and uses an appropriate connection oriented protocol. Supported operating systems/processors are VMS(VAX), UNIX(MIPS R2000, R3000) and Software Components Group's pSOS (680x0). Connection oriented protocols are supported over Ethernet (TCP/IP) and RS232 (a package of our own design). 2 refs., 2 figs.

Portable database driven control system for SPEAR

Description: The new computer control system software for SPEAR is presented as a transfer from the PEP system. Features of the target ring (SPEAR) such as symmetries, magnet groupings, etc., are all contained in a design file which is read by both people and computer. People use it as documentation; a program reads it to generate the database structure, which becomes the center of communication for all the software. Geometric information, such as element positions and lengths, and CAMAC I/O routing information is entered into the database as it is developed. Since application processes refer only to the database and since they do so only in generic terms, almost all of this software (representing more then fifteen man years) is transferred with few changes. Operator console menus (touchpanels) are also transferred with only superficial changes for the same reasons. The system is modular: the CAMAC I/O software is all in one process; the menu control software is a process; the ring optics model and the orbit model are separate processes, each of which runs concurrently with about 15 others in the multiprogramming environment of the VAX/VMS operating system. 10 refs., 1 fig.
