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%.


- Preliminary MUI V3 support

- A couple of very important bug fixes

- The Meter-client can now draw graphs

- Many other improvements and bugfixes.


AmigaDos 2.04 or newer is required to run Executive.


Any Aminet site, for example:

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


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
(10 GBP, 20 DEM, 70 FIM, ...).
