                              DEC POP 11/70

    The DEC POP 11/70 is the primary computer resource used at ERLGB.
It provides services to administration, scientists, the Library
and other EPA branches; it is also the link to the NCC IBM.  It is central
to all data processing activity of the laboratory and is accessible from
virtually all locations on the Island.
    The Computer Resource Group staffs the POP 11/70 and
encourages EPA and contract employees to take advantage of the many
services it offers; whether it is adopting pre-existing programs or
developing new programs to suit a particular need.
    The following will show some of the options available for use.
    If further, more specific information is needed contact the System
Manager, Lin Donnalley.
                                   1-1

-------
A.  WHO HAS ACCESS TO THE SYSTEM?

    The POP 11/70 is available to all EPA and contract employees.
    An account is necessary before access to the computer is granted.
    An account may be established by seeing the System Manager,
    Lin Donnalley.  She will  give you a password to protect programs
    and data and will brief you on backups and security features which
    are followed to ensure the integrity of data collection and analysis,

        environment when conducting toxicity studies,  LOGIT
        linearizes the logistic sigmoid curve.

    d.  BIOFAC
        BIOFAC is a program that characterizes the rates  of uptake
        and clearance of chemicals in aquatic organisms.   It
        generates optimal estimates of the rate of constants from
        a set of sequential time-concentration data.   This program
        because of its size, is executed through the  NCC  IBM,
        using data acquired locally.

    NOTE:  The application programs stated above are  programs already
    written.  The POP 11/70 is not limited to running only these
    programs.  Programs can be written to serve almost any purpose.
    For further information see the System Manager, Lin Donnalley.

    chief.  The job request forms are for the initiators benefit,
    they allow an organized method for the POP 11/70 staff to
    ensure that the request was properly identified, authorized,
    accepted and performed.  The job request form may be obtained
    in the Computer Building, building 24.

4.  When a sign off message appears on the screen, please do so as
    quickly as possible.  Your cooperation in this effort will allow
    operations required for the shut down to begin and end in a
    minimum amount of time.  Work on the computer may then be resumed
    for all employees.
                               1-6

-------
                                 NCC IBM

    The IBM 3081 is provided for the EPA Laboratories by the National
Computer Center, (NCC), in Research Triangle Park in North Carolina.
Their mission is to aid EPA and contract employees in their administrative
and scientific duties in addition to the local support provided the DEC
PDP 11/70.
    Software packages such as SAS and input/output services are provided
which would otherwise not be available.   These will be listed with a
brief explanation of each in the section to follow.
    There is a charge to the laboratory for use of the IBM.  It should,
therefore, only be used when it has been determined that all other
resources of the laboratory cannot meet the user's needs.  The system
manager will assist you in this area should you have any questions.
                                   2-1

-------
A.  WHO HAS ACCESS TO THE SYSTEM?

    The IBM is connected to the laboratory through a phone line
    to the DEC POP 11/70.  This connection is activated when the
    number of jobs waiting to be sent reaches a minimum threshold
    or until a job has remained in queue for a minmum amount of
    time.  Any-EPA or contract employee with a current DEC account
    may access the IBM.  Please see the system manager, Lin Donnalley
    for job schedules and account information.

        It is available 24 hours a day except for the following:

        a.  Backups
            Monday         4:00p.m.  - 8:00p.m.

                          HEWLETT PACKARD  3357

    The Hewlett Packard multiprocessor offers a continuous real-time
facility necessary for many experimental applications.  This means data
doesn't wait for access to the processor.  Due to time-sharing utilization
and regular system shutdowns required for backups and preventive
maintenance, the DEC is not a primary resource for real-time processing
as it cannot guarantee return for additional information in a specified
amount of time.  The Hewlett Packard is also used extensively for data
collection and manipulation, and for archiving analytical data.

E.  NOTES TO USERS

1.   The Hewlett Packard provides the user with  raw data to identify
     individual data points which can provide a  more detailed analysis of
     the processed output.

2.   In the near future the Hewlett Packard will be linked to the DEC POP
     11/70, providing all of the advantages of the DEC including NCC  IBM,
     SAS, and National Communications Network with all EPA labs and
     locations.

3.   The Hewlett Packard runs 24 hours a day, and is always available for
     processing.  During back-ups data collections are continued.

                              TEKTRONIX 4051

    The Tektronix 4051, located in the Wetlab Computer Room, is
dedicated to monitoring water quality parameters.  These include raw
and filter seawater temperatures, raw, filter and control seawater
salinities, ph, dissolved oxygen and additionally, solar energy levels
striking the wetlab roof.
    This monitoring enables researchers to determine that desired water
quality levels are maintained for wetlab experiments which will not
effect data results and analysis.
    The system has been equipped with an uninterruptible power supply,
which has greatly increased dependability.  Future additions, as they
become possible, will reduce downtime even further.
    The following will provide additional  information regarding the
TEK 4051 and will direct you for further assistance.
