                         Resource Evaluation

Abstract

  In the spirit of RFC # 369, Evaluation of ARPANET resources, a new
  test group was organized at UCSB to take a detailed look at specific
  network resources and develop initial site dependent and function
  dependent MINIMAN's (Concise User Manuals).  As the group was again
  composed of novices, initial effort revolved about basic procedural
  indoctrination.  In the period between January and March 1973 a
  number of resources were investigated with varying degrees of
  success, as to availability, proper usage, sample problem solutions,
  and access to help and documentation.  Included in this paper are a
  summary of the projects undertaken, initial suggestions at MINIMAN
  composition, and suggestions for future test groups.  As these groups
  are attempting to perform a useful function for the ARPANET
  community, comments and suggestions are requested.  Copies of the
  reports described herein are available on request from the Computer
  Systems Laboratory at UCSB.

Resources Investigated by the Group

  I.  APL

     APL was investigated primarily at MULTICS.  UCSD was also
     scheduled for evaluation but not carried out.  APL at MULTICS was
     used to solve a few trivial problems.  Most effort revolved about
     the difficult task of obtaining any available documentation.  The
     octal codes for APL characters were obtained and mapped into the
     OLS keyboard.  A side goal of the project, the comparison of APL
     with OLS, was begun but progressed very little.

  II.  Basic

     Basic was investigated at a number of TENEX sites.  Differences
     between sites were pointed out and necessary file manipulation
     commands were documented.  An integration problem was written at
     one site, sent via FTP to another site, and then run again to show
     comparative execution times and compatability.  Non-PDP/10 sites
     were investigated but no report was submitted.

  III.  TSO

     IBM's Time Sharing option was exercised at UCLA-CCN.  Interesting
     results were obtained regarding cost and execution time.
     Available commands were documented and a PL/1 program was written
     and executed.

  IV.  MIT-MATHLAB

     This, the most successful of the projects, involved documentation
     of help, file manipulation, and MACSYMA access and an original
     research project in resource sharing.  A recursive problem in
     pattern recognition and a triple integration were solved to
     demonstrate MACSYMA generated expressions into user programs on
     the OLS.  More information on this project is forthcoming.

  V.  Local User Guide

     A first pass network users manual was completed for UCSB users.
     In it are described console access and settings, character
     mappings, current servers, users and TIPs, and error conditions.
     Following minor revisions this guide will be distributed to local
     users.

  VI.  Local IMLAC Access to Network

     Access to network graphics programs was attempted with a local
     IMLAC.  Due to the non-uniformity of network IMLACs very little
     success was obtained.  However, a program to access SRI-ARC's NLS
     was compiled and loaded from NIC and attempts were made to iron
     out the bugs.  In addition a project was begun to maintain an
     IMLAC library and compiler locally for network usage.  As in the
     other projects, basic operating procedures were documented.

  VII.  Harvard Graphics

     Several attempts were made to learn of availability of graphics
     access to organic molecule synthesis programs but no response
     could be generated.  This project was eventually abandoned.

MINIMAN Composition

  As mentioned in a previous report, concise manuals are needed for
  network resources so that uniniated users may gain basic familiarity
  with foreign systems.  In addition, manuals which describe specific
  network wide functions, such as Fortran compilors, are needed if
  resource sharing is to become a real trait of the ARPANET.  For the
  resources evaluated, each group member submitted two reports

  analagous to the two types of MINIMANS needed in the network.  The
  headings and format of the reports will be included here to stimulate
  future discussion on MINIMAN composition.

  REPORT # 1: Online Help for [a specific host computer]

        I.  Connection, Login, and Optimal TELNET Settings

       II.  Help Files

      III.  Job Status

       IV.  Time of Day

        V.  Time/Money  Used/Left

       VI.  Interpersonal Communications

            A. Console Linking

            B. Location of Users

            C. Mail Facilities

            D. Access to Operator and/or Consultants

      VII.  Warnings or Unfriendly User Behavior

     VIII.  Useful References and Documentation

  REPORT #2: How to Use [a specific resource]

        I.  Table of Contents

       II.  Access and Usage (or How to Start and Stop)

      III.  Editing Commands and File Structures

       IV.  Documentation, Location, and Cost

        V.  Sample Solutions and Significant Problems

       VI.  Appendices

            A. Special Characters and Terminal Settings

            B. Similarities and Differences from Site to Site

Future Test Groups

  A number of projects are envisioned for future resource evaluators
  and include:

  1. Complete evaluation of APL at MULTICS and UCSD with comparison to
     the On-Line System (OLS).

  2. Investigate BASIC in depth, network wide.

  3. Evaluate other symbolic manipulation programs such as REDUCE.

  4. Summarize all games available in the network.

  5. Find and evaluate specific application programs such as ZOG or the
     weather data base at CCA.

  The projects undertaken will be determined in part by local
  interests.  But a serious effort is being made for reports to
  accompany each evaluation.

Conclusion

  Good results have been obtained from the two test groups thus far.
  Although composed of novices, as far as network familiarity is
  concerned, the groups have been able to produce data and reports
  which benefit the network community.  The reports run the gambit from
  poor to excellent, but even the poorer ones have generated results by
  motivating more knowledgeable system personnel to find time to write
  the report in the "right" way.  All data and reports compiled by
  these groups are available to interested network users.  In addition,
  any information or documentation or manuals which might fit into the
  framework of the MINIMAN is requested from the network community.  As
  this information begins to be collected, the network may truly start
  to become a resource sharing network.
