History and Notes

Average CPU usage:
Displays the elapsed time and the average CPU usage for both CPU cores.
To reset the average CPU usage, double click on the elapsed time in the interface.

CPU Usage Graph and Tray colors:
To change these colors, right mouse click on the CPU usage graph in the main program interface.

Exit Program:
Right mouse click on tray icon or the very upper-right corner of interface for a menu.

Explorer.exe Note:
Setting the CPU affinity of the Windows "Explorer.exe" file may effect the CPU affinity of other programs you start afterwards!

Favorites/Auto Set CPU Affinity:
Favorites allow you to set the CPU affinity to a group of programs automatically on the fly, or with a click of a button.

Add a favorite:
Select the affinity in one of the CPU affinity check boxes (0,1, or 0+1), then do one of the following three options.

1) Select one or more file names from the programs list and click the "Add Fav" button.

2) Click the "Add" button to browse for a single file on the local computer (.Exe, .Scr, and .Lnk shortcuts).

3) Drag and drop multiple (.Exe and .Scr) files from a Windows explorer folder on the local computer into the Favorites list.

Note: When adding favorites and "Auto Set Affinity" is enabled the files affinity will also be set if the file is running.

Favorites are prefixed with a "*" character in the programs list.

Manually changing the affinity of a file in the program list is ignored if it's a favorite, but only if Auto Set Affinity is enabled.

Same named files are not allowed in the favorite list. If multiple copies of the same program are running and the CPU affinity is set from favorites (Set Now or Auto) those files will all be set to the same CPU affinity setting!

To change the CPU affinity setting of a favorite, highlight one or more favorites and right mouse click for a menu.

To disable a favorite, set the favorites affinity to "0+1". Affinity is only applied if it needs to be changed.

Your favorites are saved to the file "MyFavAff.idx" on exit.

File icons/Cache folder/Clear Cache:
Icons for files in the Program and Favorite lists are saved to the sub-folder "cache".
If a file has no icon then a picture of a small computer is used instead.

If you don't want the program to cache icons for the program list, uncheck the option "Cache Icons" in Options,

To delete all cached file icons (except for favorites) open Options and click "Clear Cache", you will then be asked if it is OK to proceed.

Get and Set Priority:
Select one file in the Programs list, then right mouse click to open the Priority menu.

Hiding file names in program list:
Allows you to hide files names that you don't want to adjust (protect from changes) or normally see in the programs list.

To hide files, select one or more file names in the programs list and click the "Hide" button.

To un-hide, enable the "Show All" check box, select one or more file names and click the "Un-Hide" button.

Note: You can not hide a file name if it is in your favorite list.

When "Show All" is enabled, file names that are marked as hidden are prefixed with the "<" character.

File names you mark as hidden are saved to the text file "Ignore_List.txt" on exit. You can edit this file with Notepad to manually add or remove file names, use one file name per line. You must exit GnS Affinity before editing the file! Download a sample Ignore List.

High Priority:
When your PC is under heavy work loads GnS Affinity may be slow to respond, enable this option if needed.

Limitations/Known Issues:
1) Supports file names up to 34 characters long.

2) When GnS Affinity is open on the desktop and a program is launched there may be a short delay before the programs real icon is displayed.

3) Program Usage Graphs may close unexpectedly. i.e. Child windows, Window handles that change, etc,

4) The elapsed time in main interface will be incorrect when the PC clock is changed manually or on day light savings change.

Options:
To open, click "Options" button or right mouse click on the very top-left of the title bar where it reads, "Get and Set CPU Affinity".

To change the interface or text color,
Click on a color box and/or adjust the Red(R), Green(G), Blue(B) & brightness controls.
Click Apply to save.
Click Undo to load your last saved colors.

Program Usage Graph:
Displays the total CPU usage of a program in a small graph.
To open a graph, double click on a file name in the programs list.

Right mouse click on the graph for options...
Graph Time is the time it takes to fill the graph from right to left.
1 minute - Updates graph every 600ms (Default setting).

5 minute - Updates graph every 3 seconds.

Note: Graphs auto close when the executable they are monitoring exit, unless they are windowless types.

Allows you to reset your user settings such as the color, size, position of the program to the default values.
This does not remove your favorites or file names you have marked as hidden.

To reset settings, open Options and click on "Delete User Settings", you will then be asked if it is OK to proceed.

Settings are saved to the the registry at "HKEY_CURRENT_USER\Software\VB and VBA Program Settings\Edgemeal\Get and Set CPU Affinity".

This program allows you to start and stop Windows XP services manually or a group of services using profiles.
