Processor Affinity - Add Set Affinity to Context Menu

AtotehZ · Mar 20, 2013

Hello,

This is just what I need. I have to set cpu affinity for my program every time I launch it.

How can I add the batch scripts to each other? From 0-11 I need only want 4-11 to run the program. Otherwise it hangs.

Do I just open them in an editor and add them to each other in one batch?

Hello Atoteh,

Sure, you could add the contents of each .bat file into just one .bat file instead if you like.

So this:

Code:

@ECHO OFF
REG ADD "HKCR\exefile\shell\Run with CPU-4 Affinity" /ve /f
REG ADD "HKCR\exefile\shell\Run with CPU-4 Affinity\Command" /ve /t REG_SZ /d "cmd.exe /c start \"Run with CPU-4 Affinity\" /affinity 5 \"%%1\"" /f
REG ADD "HKCR\exefile\shell\Run with CPU-5 Affinity" /ve /f
REG ADD "HKCR\exefile\shell\Run with CPU-5 Affinity\Command" /ve /t REG_SZ /d "cmd.exe /c start \"Run with CPU-5 Affinity\" /affinity 6 \"%%1\"" /f
REG ADD "HKCR\exefile\shell\Run with CPU-6 Affinity" /ve /f
REG ADD "HKCR\exefile\shell\Run with CPU-6 Affinity\Command" /ve /t REG_SZ /d "cmd.exe /c start \"Run with CPU-6 Affinity\" /affinity 7 \"%%1\"" /f
REG ADD "HKCR\exefile\shell\Run with CPU-7 Affinity" /ve /f
REG ADD "HKCR\exefile\shell\Run with CPU-7 Affinity\Command" /ve /t REG_SZ /d "cmd.exe /c start \"Run with CPU-7 Affinity\" /affinity 8 \"%%1\"" /f
REG ADD "HKCR\exefile\shell\Run with CPU-8 Affinity" /ve /f
REG ADD "HKCR\exefile\shell\Run with CPU-8 Affinity\Command" /ve /t REG_SZ /d "cmd.exe /c start \"Run with CPU-8 Affinity\" /affinity 9 \"%%1\"" /f
REG ADD "HKCR\exefile\shell\Run with CPU-9 Affinity" /ve /f
REG ADD "HKCR\exefile\shell\Run with CPU-9 Affinity\Command" /ve /t REG_SZ /d "cmd.exe /c start \"Run with CPU-9 Affinity\" /affinity 10 \"%%1\"" /f
REG ADD "HKCR\exefile\shell\Run with CPU-10 Affinity" /ve /f
REG ADD "HKCR\exefile\shell\Run with CPU-10 Affinity\Command" /ve /t REG_SZ /d "cmd.exe /c start \"Run with CPU-10 Affinity\" /affinity 11 \"%%1\"" /f
REG ADD "HKCR\exefile\shell\Run with CPU-11 Affinity" /ve /f
REG ADD "HKCR\exefile\shell\Run with CPU-11 Affinity\Command" /ve /t REG_SZ /d "cmd.exe /c start \"Run with CPU-11 Affinity\" /affinity 12 \"%%1\"" /f

..would result in my CPU affinity being set to CPU- 0 to 3 off and CPU- 4 to 11 on?

Can this be done for a specific *.exe only? I mean, can I still let other processes run on CPU- 0 to 3? Is there a way to clean it up a bit? Maybe 2 strings that sets the affinity of all instead of 16, 2 for each processor core.

I know how to add to the registry at the same time as I launch the program, but I don't know how to make the removal batch run automatically when I close the program. How is that done?

***UPDATE***
I found a solution that fits my problem better. I will let the rest of my question stay though, maybe others can get use of that.

This command line sets the CPU affinity for the program as you start it:
C:\Windows\System32\cmd.exe /C start "" /affinity XX "*PATH OF PROGRAM*"

XX = The hexadecimal number for the logical processors you want to use.

1 = use CPU 0
2 = use CPU 1
3 = use CPU 1 and 0
4 = use CPU 2 ...
9 = use CPU 3 and 0
A = use CPU 3 and 1 ...
F = use CPU 3, 2, 1 and 0

If you have a lot of CPUs to choose from you might wanna use binary numbers and convert it to hexadecimal afterwards.

1 = use CPU 0
10 = use CPU 1
100 = use CPU 2
...
100000000000 = use CPU 11
110 = use 1 and 2
101010101010 = use CPU 11, 9, 7, 5, 3 and 1

The placement of a certain digit represents a certain processor. The value of that digit represents if the processor is to be on or off.

You can convert it here:

Hope I helped a little in return for your time

hmm what about making casscade context menu with this content ?, could smone explain me why my context menu dont reveal when i get mose on exe and move over entry ive created by code below

Code:

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie]
@=""
"SubCommands"="cpu0123;cpu123;cpu23;cpu2;cpu3"
"Icon"="%windir%\\System32\\SetupApi.Dll,21"
"MUIVerb"="Koligacja procesorów"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu0123]
@="CPU - 0,1,2,3"
"icon"="%windir%\\System32\\NetCenter.Dll,12"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu0123\command]
@="cmd.exe /c start \"rdzenie\" /affinity f \"%1\""
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu123]
@="CPU - 1,2,3"
"icon"="%windir%\\System32\\NetCenter.Dll,11"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu123\command]
@="cmd.exe /c start \"rdzenie\" /affinity e \"%1\""
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu23]
@="CPU - 2,3"
"icon"="%windir%\\System32\\NetCenter.Dll,10"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu23\command]
@="cmd.exe /c start \"rdzenie\" /affinity c \"%1\""
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu3]
@="CPU - 3"
"icon"="%windir%\\System32\\NetCenter.Dll,8"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu3\command]
@="cmd.exe /c start \"rdzenie\" /affinity 8 \"%1\""
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu2]
@="CPU - 2"
"icon"="%windir%\\System32\\NetCenter.Dll,8"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu2\command]
@="cmd.exe /c start \"rdzenie\" /affinity 4 \"%1\""

@ belowed files works, but only on exe files, what to add to make it possible on liks to exe files ( content menu shows on lnk to exe but nothing happens ;P)

Code:

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie]
@=""
"SubCommands"=""
"Icon"="%windir%\\System32\\SetupApi.Dll,21"
"MUIVerb"="Koligacja procesorów"
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie\Shell]
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie\Shell\cpu0123]
"muiverb"="CPU - 0,1,2,3"
"icon"="%windir%\\System32\\NetCenter.Dll,12"
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie\Shell\cpu0123\command]
@="start "Koligacja CPU - 1,2,3" /affinity E %1 & pause"

Brink · Oct 4, 2016

Hello kkmks,

This should work for you instead. You just had the command incorrect a bit.

Code:

Windows Registry Editor Version 5.00
 
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie]
@=""
"SubCommands"=""
"Icon"="%windir%\\System32\\SetupApi.Dll,21"
"MUIVerb"="Koligacja procesorów"
 
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie\Shell\cpu0123]
"muiverb"="CPU - 0,1,2,3"
"icon"="%windir%\\System32\\NetCenter.Dll,12"
 
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie\Shell\cpu0123\command]
@="cmd /c start \"Koligacja CPU - 1,2,3\" /affinity E \"%1\""

yeah it works on exe files, but it won work on shortcuts ;'(thats wahts makes me all the problem here ;P
who run program directly from original exe ;P
what is strange that your original non cascade files works fine even with lnk

Brink · Oct 4, 2016

What I posted worked on a shortcut of notepad.exe for me.

As a test, create a new shortcut of notepad.exe to see if it works for you as well.

deleted685 · Oct 4, 2016

nope win 7 x 64 dont respond ;P but thx 4 trying

Brink · Oct 4, 2016

Ok. Let's strip it back down to a non cascading context menu to see how it works for you with this below.

Code:

Windows Registry Editor Version 5.00
 
[-HKEY_CLASSES_ROOT\exefile\shell\rdzenie]
 
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie]
@="Koligacja procesorów"
"Icon"="%windir%\\System32\\SetupApi.Dll,21"
 
[HKEY_CLASSES_ROOT\exefile\shell\rdzenie\command]
@="cmd.exe /c start \"Run with CPU-0 Affinity\" /affinity E \"%1\""

deleted685 · Oct 4, 2016

as said earlier non cascade works great

but im planning ot add 10 variants so ...
im trying right now to make some files in windir to run for now batch but probably will try to use vbs or maybe powershell to catch just runned process

Brink · Oct 4, 2016

Yep, I know. I just wanted to verify if it was an issue with the current command or something else.

deleted685 · Oct 4, 2016

hmm could it work with exefile extensions and links ?[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\cpu123\command] ???

Brink · Oct 4, 2016

No. It would need to only be on application file types instead.

As a test, download and merge the .reg file for the listed .lnk item in the tutorial below to restore its default associations and registry entries to see if that may help.

Default File Type Associations - Restore

deleted685 · Oct 5, 2016

hmm ive checked the reg files and dont apply whole, beacuse of my additional keys inside some nvxxxxxx keys, but lets go to sum all up:
after comparison my registry with file iv looked that i ve been mising of:

Code:

[HKEY_CLASSES_ROOT\InternetShortcut]
"IsShortcut"=""

additionally im not sure that ive checked belowed strings precisely what are inside:

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Icons]
"29"=-

[-HKEY_CLASSES_ROOT\SystemFileAssociations\.lnk]

[HKEY_CLASSES_ROOT\SystemFileAssociations\.lnk]
"FileOperationPrompt"="prop:System.ItemTypeText;System.FileOwner;System.Author;System.Title;System.Subject;System.Comment;System.DateModified;System.Link.TargetParsingPath"
"FullDetails"="prop:System.PropGroup.Description;System.ItemTypeText"

BUT EVERYTHING START TO WORK AFTER APPLY BELOW REG FILES, so it seems that ive trapped myself making much mods to my os

(shred to much)

Code:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\InternetShortcut]
"IsShortcut"=""

[HKEY_CLASSES_ROOT\piffile]
"IsShortcut"=""

[HKEY_CLASSES_ROOT\WSHFile]
"IsShortcut"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Icons]
"29"=-

[-HKEY_CLASSES_ROOT\SystemFileAssociations\.lnk]

[HKEY_CLASSES_ROOT\SystemFileAssociations\.lnk]
"FileOperationPrompt"="prop:System.ItemTypeText;System.FileOwner;System.Author;System.Title;System.Subject;System.Comment;System.DateModified;System.Link.TargetParsingPath"
"FullDetails"="prop:System.PropGroup.Description;System.ItemTypeText"

So thx for advises everything is working now

( good taht i have copy of code here ;P)
Personally im thinking ( why i dont make backup and checked it ;P <facepalm>) that \SystemFileAssociations structure was the point of problem

later when im done with my things ill check on similar one machine and post precisely which registry keys does the thing

Brink · Oct 5, 2016

Great news. I had a suspicion that something was off with your .lnk registry entries. :party:

Those are also part of setting .lnk back to default, and are safe if wanted.

Sorry for relive the post and sorry for my English again. This option about affinity works in Windows 7, at least to me, if I choose run application with 2 cores, it works, but in Windows 10 1709 doesn't work ... There are any way to solve? It's a very interesting option and useful for me.

Greetings and thanks.

Brink · Apr 23, 2018

Hello Triceratops, and welcome to Seven Forums.

It would be best to ask about Windows 10 at our sister site www.tenforums.com instead.

Thanks for welcome and for responding.

It's a pitty, :sarc:

, i don't know why, but now it doesn't work in Windows 7 for all cores, only CPU-0 works correctly.

I will ask at tenforums. Thank you.

Triceratops · Apr 23, 2018

Aaaahhh, i've got (I think) that it works thanks to your info and the video of this link of forum, hahaha:

How to access screen without Task Manager? - Windows 7 Help Forums

It's a long process but I think that I solve it.

If I get to create the reg file (for 4 cores, my processor has 4), I post it here if you want and you think that it's suitable.

Greetings.

PD: I don't know if my English is understandable.
