The System Area provides detailed information about the system settings of the current CYC® image, operations queues, and transcripts, as well as allowing the user to perform operations such as halting the CYC® image or loading CYC® patches.

System Settings

"Current machine" shows the machine the CYC® image is running on.

"Current image number" shows the particular image number (uniquely identified by the date the CYC® image was started up on this particular machine). For example,

	CLIO-1-19970505093744
means that the CYC® image was started up on Clio on May 5, 1997 at 9:37:44am.

"Image start time" displays the date and time the image was started and how long the image has been up and running.

"Current KB" lists the current version of the Knowledge Base, and will be updated when KB operations are loaded into the current CYC® image. Generally, a new CYC® image will be started up with a whole-number KB version (this number appears next to "KB" in the System Status frame at the bottom of the screen). Then, the number to the right of the decimal will match the total number of trancript operations that have been read (line #1 below). For example,

	93.1064
would usually mean that the current image was started up with KB 93, and a total of 1064 operations have been read (but not necessarily processed). To see how many operations have been processed, see the Operations Queues section below for an explanation.

"System and patch level" lists the current version of the SubL code, including the patch level. For example,

        41.19
means that the CYC® image is based on version 41 of the SubL code, and the patch level (number of updates to this version of the SubL code) is 19.

C, NT, LISP (LispWorks/Allegro) images: clicking on "here" in the tagline at the bottom of this section will halt the CYC® image; there is a safety confirmation built into this option, since unintentionally halting the CYC® image will most likely have undesired consequences. LISP (Genera) images are generally not halted using the HTML interface; instead, LISP (Genera) machines are controlled via the command line interface on the LISP machine, which is best left up to those familiar with the LISP (Genera) machines.

LISP (Genera) images: clicking on "here" in the tagline at the bottom of this section will load patches, effectively bringing the SubL code up-to-date for the CYC® image. Loading patches is part of the CYC® Agenda's job, though it is occasionally necessary or desirable to load them by hand. C, NT, and LISP (LispWorks/Allegro) images do not load patches, instead catching up when a new world is built at compile time.

Queue Information

This section offers a more detailed description of the operations queues that appear in the Agenda Status Bar. There are 3 queues,

broken up into 3 sections, starting at the top:
  1. Remote
  2. Local
  3. Auxiliary (will only appear if queue is non-empty)

Transcript Information

Depending on the communication status, operations processed by a CYC® image may be written out to a special file called a transcript file. For every image, there are two relevant kinds of transcript files:

To view the contents of either the Master or Local Transcript, simply click on the highlighted name. A word of caution: the master transcript can get a bit long, and so may take some time to load.

Below the name of the Master Transcript, the number of characters and estimated number of operations in the transcript are displayed. The actual number of operations read is listed as well.

Below the name of the Local Transcript, the number of operations in the file is listed.

If either transcript has 0 operations, it is empty.

Historical Information

At the bottom of the System Area, a summary of queue/transcript information is presented: For details on communication status settings and transcript files, see the CYC® Agenda and Transcripts Documentation.
