Short: UNIX-like task scheduler (V1.20)
Author: petrin@megabaud.fi (Petri Nordlund)
Uploader: petrin@megabaud.fi (Petri Nordlund)
Version: 1.20
Type: util/misc
Requires: AmigaDos 2.04
Replaces: util/misc/Executive.lha
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%.
----------------------------------------------------------------------
The most notable changes in this release are:
- 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.

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