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
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
- 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.

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, ...).
