DESCRIPTION

     Executive is a UNIX-like task scheduler for Amiga. It also has
     plenty of other features previously available only in larger
     operating systems.

     Executive improves the responsiveness of your Amiga. No longer
     running a CPU intensive program causes the whole machine to slow
     down. You can start many CPU intensive programs and the machine
     still feels as fast as before.

     Executive also includes many useful client programs which let you
     control tasks and monitor what's going on in your system.

     The core of Executive is a scheduler that recalculates task
     priorities based on system load average and task's recent CPU usage.
     The scheduler will give high priority to interactive tasks and low
     priority to CPU intensive tasks.

     Executive is similar to Job Manager or Spy System, but it has more
     features than these two together, for example:

     - highly accurate (1/1000 seconds) CPU usage timing
     - 6 different scheduling algorithms
     - load averages
     - process identifiers
     - process group identifiers
     - accounting
     - focus - task with active window gets more CPU time
     - support for MultiUser

     Executive consists of a server and clients. The server is run
     in the background and it takes care of scheduling, CPU usage
     calculations and many other things. The client programs are:

       acct            Accounting daemon
       ALoad           Display load average or CPU usage
       ALoad3D         Display load averages in 3D
       Commander       General task manager
       ctp             Extended ChangeTaskPri
       kill            Extended Break
       lastcomm        List last commands executed
       Meter           Display system information
       nice            Run programs with lower scheduling priority
       ps              Process status displayer
       pstree          Display child-parent relationships
       renice          Renice a task
       sa              Display accounting statistics
       stat            Display some misc. information
       timer           Time CLI and Workbench programs
       top             Display information about top CPU tasks
       uptime          Display system uptime and load averages

     Executive doesn't use any illegal programming, it is fully compatible
     with all Amiga computers running AmigaDos release 2.04 or newer.

     Executive has been carefully designed to work with all kinds of
     configurations and care has been taken not to break any programming
     rules.

     It's not possible to give a full description of all Executive
     features here, so try it out. You don't want to use your Amiga
     without it.

     Executive is the highest rated item of shareware CU Amiga magazine
     has ever awarded at 98%.

NEW FEATURES

    - Meter, a new client for registered users. Meter displays all kinds
      of system information in a small, customizable window.

    - System is now scanned during installation for programs in the
      ExecutivePrefs Magic Wand list and these are added to the
      preferences file automatically. Existing preferences file is
      also updated.
  
    - Some changes were made to all schedulers. I have especially spent
      a lot of time improving the Queues-scheduler. The changes I have
      made make it the best scheduler in Executive. It's a real killer
      now (maybe I should rename it to "O.J."?)
  
    - There's now a Common problems -section in the docs.
  
    - Server now defaults to using CIA-B timer on 68020+ machines so the
      CIA-A timer is left free for programs that aren't wise enough to
      use CIA-B timer if CIA-A is reserved.

    - Many other improvements and bugfixes.
  
SPECIAL REQUIREMENTS

     AmigaDos 2.04 or newer is required to run Executive.

AVAILABILITY

     Any Aminet site, for example:

     ftp://ftp.luth.se/pub/aminet/util/misc/Executive.lha

     Executive has a WWW-page which has links to several Aminet
     sites and also some nice screenshots. The page URL is:

PRICE

     The freely redistributable version doesn't lack any crucial features
     so it can be used without registering. Registered users get
     process accounting, ALoad3D and Meter clients and 5 additional
     scheduling algorithms. Registration fee is $15 and it's also accepted
     in various other currencies.
