The last four FORUMs ( or should it be FORA? ) have been produced to our new monthly schedule and the last two have included some statistics. However, as with most such newsletters it is difficult to know whether the information inserted is of the right kind or pitched at the right level. It is tempting to assume that "no comment" implies perfection, but it could be an indication of something less! Since most of you, the users, have access to one of our systems which provides POST facilities to User Interface, we would like to hear from you on the subject, even if it is a mere "It's all right".
In addition we believe it would be helpful to publish letters from users. In order to do that, of course, we have to receive some! Again, automatic means of communicating with us are available and can be used for such a purpose. Our level of service in general can only be improved if our main method of contacting all our users is a two-way process.
2. CHANGES AT RAL
Dr G H Stafford CBE FRS relinquished his post as Director General of the Rutherford and Appleton Laboratories on 30 September 1981. With the completion of the merging of the two Laboratories, the RAL will in future be known as the Rutherford Appleton Laboratory. Dr G Manning will be the Director and Professor J T Houghton has been appointed as the Deputy Director with the title Director Appleton. Within the RAL there are now Associate Directors, each responsible for areas of work funded by the various SERC Boards. Professor Houghton will be responsible for the programmes funded by the Astronomy, Space and Radio Board within the Laboratory. Dr D B Thomas will be responsible for those of the Engineering Board and Dr J J Thresher for those of the Nuclear Physics Board. For the time being Dr Manning will be responsible for the programmes of the Science Board and for the Laboratory's technical services, including computing.
These changes have come into effect from the beginning of October 1981. They principally affect the manner in which communication between the RAL and the Central Office is handled. Users of the computing facilities managed by RAL, whether IBM MVT batch, IBM CMS, or SERC ICF, should continue to deal with the Computing Division as hitherto.
3. CENTRAL COMPUTER PROCUREMENT
FORUM 14 gave a brief note on the Computer Review Working Party Report and its recommendations for the replacement of the Central Computers at Rutherford Appleton Laboratory. An Operational Requirement has now been produced for the central computer replacement plan. Essentially it proposes:
- An IBM-compatible system which can handle at least the batch load currently run on both our 3607195s. This would enable the 360/195s to be replaced and in time a move made to manufacturer-supported Operating Software (MVS).
- An IBM-compatible system to replace the 3032 by a product which is at least 1.5 times the power and which is upgradeable. This would enable the front-end service to be extended and MVS development to begin.
The SERC Central Computing Committee has agreed that an invitation to tender, based on this requirement, should be issued as soon as possible. Although the Five Year Forward Look makes no significant finance available until April 1983, the replacement programme will be brought forward if any funds can be made available before this time.
A development plan for the transition to the MVS system will be produced early next year and this will begin as soon as suitable hardware can be installed.
4. IBM VS FORTRAN PROGRAM
The IBM VS Fortran Compiler (Release 1.0) has been installed on CMS. This compiler contains support for the ANSI Fortran standard known as Fortran 77-The compiler contains an option to indicate deviations from the ANSI standard and also has the capability of compiling programs written in the Fortran 66 standard (set compiler option LANGLV(66)).
As the compiler requires a very large amount of virtual storage, it can only be run in the CMSBATCH virtual machine at present. It is hoped to be able to run the compiler in users' own machines eventually, after some software modification has taken place.
To invoke the VS Fortran compiler use the BATCH EXEC as follows:
BATCH fn (FORTVS
See HELP BATCH for full details of the BATCH EXEC. Details of the compiler options available can be found in HELP FORTVS. A new system library containing I/O routines etc must be connected to your machine at LOAD time. This library is called VFORTLIB. It is connected to a user machine via GLOBAL TXTLIB VFORTLIB CMSLIB etc and must be used instead of the old Fortran library FORTLIB. Note that the libraries are not interchangeable. Additional libraries such as NAGLIB and RHELIB etc can be used in their present form.
A complete set of reference documentation for this compiler and library is available in the Program Advisory Office. Compilation messages are prefixed with the code IFX and are considered to be self-explanatory. Library messages are prefixed with the code IFY and are again self-explanatory in most cases.
The compiler as delivered by IBM does not support any optimisation levels (NOOPTIMIZE only permitted). It is expected that a compiler supporting at least some of the optimisation levels will be available during the last quarter of 1981.
A list of suspected bugs discovered by CERN and RAL in this compiler can be found by issuing the command NEWS FORTVS.
The compiler and library have been tested under MVT at RAL and found to work but the compiler required a large region. It is not designed for running under MVT. Consequently it has been decided not to provide this compiler under MVT at the moment, particularly as it contains no optimisation levels. It may be possible under MVT to license the library only if users consider this a requirement.
5. EXTRACT FROM MINUTES OF PRIME USER MEETING HELD AT ATLAS CENTRE 3/9/81
A meeting of user representatives was held at RAL on 3 September 1981 and the following items from the minutes may be of interest to readers.
Reorganisation of the IGF
A new committee structure has been implemented. The Central Computing Committee is now responsible for all hardware on all machines while the Engineering Committee handles all application software. C W Trowbridge is the RAL representative. UMIST is now in charge of PRIME User Support Services.
UMIST have now taken over Central Support for PRIME computers. All queries at each site are entered into a local GRIPE file held in NEWS. The site manager provides first line support for these queries and UMIST access the GRIPE file weekly to answer unsolved problems. This method provides UMIST with an overall view of the types of problems arising, highlighting where improvements in documentation on the system could be made. A representative from UMIST is prepared to come out on call to a site and normally tries to visit each site at least twice a year. Documentation is now prepared by UMIST. They are currently writing PRIME manual version 5 and updating the HELP system which should be ready by the release of REV 18. UMIST are prepared to run courses for users, such as the Advanced Fortran course held at PAL in May. Information about courses are supplied ir, the UMIST newsletter. It is proposed that relevant items from the newsletter and details of courses should be inserted in FORUM in future.
Most sites now run a version of PRIMOS REV 17.3. REV 18 should be available in 2-3 months but is awaiting the manpower to test it. The most noticeable change will be the introduction of CPL -the new Command Processing Language to replace the Macro system. For the first year MACRO and CPL will run in parallel but MACRO will not be supported from REV 18. Documentation about CPL will be available to users on request and will replace the MACRO scheme in the manual.
A new filenaming convention will be introduced at REV 18 and documentation is available on request. There will be an increase in memory from 1 October for all PRIME 750s to 2 Mbytes and all PRIME UOOs and PRIME 550s will be increased to 0.75 Mbytes. SOFTWARE TOOLS will be purchased for any site requesting it. It runs with PRIMOS and has a screen editor for suitable terminals. It behaves like UNIX shell.
Batch jobs running on PRIME A and PRIME B at RAL and on UMIST PRIME will be charged at 0.8 of the current rate except overnight when the rate will remain at 0.1.
Three proposals for improving PRIME security were made.
- The command STATUS USERS will only be available when logged in.
- All users will automatically be given a password when issued with a username. A null password will not be allowed.
- Non-owners will have no file access by default.
Applications and Special Interest Groups
The eight Special Interest Groups are:
Electromagnetics, Finite Elements, Digital and Analogue Circuit Design, Central Engineering, Artificial Intelligence, Tools for Interactive Programming, Computer Aided Architecture Design and Time Series Analysis, which last may be set up.
Each group provides information and software packages about specialised topics.
There are two ways of obtaining PRIME documentation:
- By private purchase from PRIME. Any user wishing to purchase manuals from PRIME should tell his manager or documentation officer who can order from PRIME (the user meeting the cost) .
- Free from site manager. RAL produces photocopies of all manuals and sends to site managers on request.
PRIME User Group meetings are held twice a year, the next being in March at UMIST.
6. QUESTIONS RAISED AT CCR MEETING 13/7/81
- Q25. How do you make a comparison between an ELECTRIC AU and a CMS AU?
- A25.Subjectively we feel that the CMS service is "twice as good as" ELECTRIC and therefore we have introduced a factor of 2 between the respective AUs (1 CMS AU = 2x1 ELECTRIC AU). (M R Jane)
- Q26. Could the charging factor be reduced on public holidays? Could it be reduced after 5pm?
- A26. The charging factor is reduced on public holidays. The charging factor is not static and may be varied in the light of experience. (M R Jane)
- Q27. In installations where there is a mix between internally and externally funded people do you seek to sell as much time as possible?
- A27. We are only permitted to sell spare time and are not allowed to act like a commercial bureau. (M R Jane)
- Q28. Our AUs run out every week. What can we do about it?
- A28. By the beginning of September when we begin policing these allocations, we expect (in collaboration with Category Representatives and users) to have got them reasonably correct. Any errors will be investigated immediately. Problems which indicate inadequate allocations should be addressed to your Category Representative. (M R Jane)
- Q29. Is there a minimum allocation of AUs per week?
- A29. Yes. CMS AUs are allocated per H week accounting period. Minimum allocation for these is 0.5 AU. Any inadequacies should be taken up with the Category Representative. In future Grant Applications will have to request CMS and ELECTRIC allocations. This will mean a particular grant will have its own allocation subject to an annual minimum equivalent to 0.5 AU per Accounting Period. (M R Jane)
- Q30. Wasn't July/August a bad trial period to use when choosing time periods as this is a time of low usage?
- A30. The parameters in the algorithms for calculating the CMS and ELECTRIC allocation units are in no way hard and fast. They will be continually monitored and modified if necessary after giving adequate notice to users. (M R Jane)
- Q31. If users are allowed to login outside prime shift when their allocation is exhausted, how does this tie in with the charging algorithm?
- A31. They will still be charged. (M R Jane)
An Introductory Course to the IBM System which covers the MVT system (but not ELECTRIC), CMS, data management and graphics will be held on two occasions, provided there is sufficient demand. The dates are 16-19 November and 14-17 December, starting and finishing at lunchtime. Applications should be sent to Miss J E Barker, User Interface Group, Computing Division, Atlas Centre. Applicants should give their names, identifiers, date of first use of the system and indicate which dates are preferred and whether accomodation will be recuired.
