Setting Processor Affinity

[IanQ]

Is there a way via batch to set a program's processor affinity so that
the program starts up using whatever cpu I want? I was kind of hoping
the 'start' command would allow this, but it only sets priority.

ie: I want via batch to have Firefox start up using only cpu 1.

I searched and searched and came across a little program called
affinity.exe, but what I don't like is that this app leaves it's
command window open after loading the app I wanted loaded, meaning if
I execute what I stated above, I get Firefox open, but also am stuck
with a command window that needs to be closed manually.

Thx

Can you use affinity.exe in a batch file and use the EXIT keyword as the last
line?

[IanQ]

Nope, the batch command window closes, but the command window for Affinity.exe stays open.

  Can you use affinity.exe in a batch file and use the EXIT keyword as the last
  line?

I thought this might be possible using rundll32 and kernel32.dll, but now I
don't think so because you would need launch the process, open a handle to
the running process, then make the affinity change.  Trying to make the
affinity change with just the PID does not work.  It can be done this way in
VBA, but probably not with batch commands.

I would search for an alternative to affinity.exe; I remember seeing others.
Here's one:

Well, xcpu does indeed set affinity without leaving a command window open, only problem with it is that it starts the application minimized.

Getting closer!

Untested:

xcpu –a 1 –p 3 –c start "" /max "d:\lightwave\programs\lightwav.exe"


Another option is to use something like cmdow.exe to maximise the window after
it has been started.

[IanQ]

Great idea, one change as don't need the double quotes:

xcpu -a 1 -p 3 -c start /max "d:\lightwave\programs\lightwav.exe"

So to have it start with the window size as Normal, it's as simple as:

xcpu -a 1 -p 3 -c start "d:\lightwave\programs\lightwav.exe"

Thanks again!

Here's another:

This one limits a process to the first processor:

Set default processor affinity for an application:

Am I missing something,

Is it not as straight forward as the following line in your batch

cmd /c affinity firefox

Nope, still leaves the command window open until the firefox app is closed.

xcpu does the trick, plus offers up priority scheduling should I ever need need it, whereas affinity.exe only set affinity.
