Executive brings real multitasking to AmigaOS. Executive is a UNIX-like
process scheduler for Amiga. It also has plenty of other features
previously available only in larger operating systems.
Executive improves the responsiveness of your Amiga. One CPU intensive
application no longer causes the whole system to crawl. You can start many
CPU intensive applications and the system still feels as if it would be
The Executive package also includes many useful client programs that let
you control tasks and monitor what is 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
Lets say you are printing a document from a word processor. You can't do
much else while the document is being printed. This isn't multitasking.
With Executive you could also do some heavy rendering and C-compiling in
the background at the same time. You could surf the web with your favorite
browser without even noticing all these programs running in the background.
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. Some important features of the server:
- precise (1/1000 seconds) CPU usage timing
- six different scheduling algorithms
- load averages
- process identifiers
- process group identifiers
- focus - task with active window gets more CPU time
- MultiUser support
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
Dashboard The mother of all meters
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 shell and Workbench programs
Top Display information about top CPU tasks
Uptime Display system uptime and load averages
Executive is fully compatible with all Amiga computers running AmigaOS
release 2.04 or newer.
Executive is the highest rated item of shareware CU Amiga magazine has ever
awarded at 98%. Executive V2.00 got 97% from the same magazine, and it was
ranked as "the best shareware utility ever."
- This version fixes two very important bugs
AmigaOS 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 URL of the page 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 many other currencies.
