### Affinity and Priority

NTDEV
1

Does anyone know how - or know an app I can buy - that will do the
following:

I have several programs that I use for FPGA design at FLE. These
programs are quite memory/processor intensive.

I would like to automatically link the task name of the program (such as
par.exe) with a specific processor affinity and priority. That way, when
I launch the program - windows will automatically map it to the right
processor and at the right priority.

Changing these settings can literally shave 20-30 minutes of compilation
time for some of our designs.

Thanks

You can use the start command in cmd.exe to assign priority. You should
be able to create an app which will assign affinity at run time(task
manager can do it).

Thanks! Here I am thinking drivers and fancy code…just a batch file
will do for me.

You do not need to set affinity, Windows will do this itself. You can set
the priority using Task Manager.

Affinity is inherited by the thread from the process when a new thread
is created. It is inherited by a child process from the parent process
when a new process is created. If there is no parent process, then the
affinity is set to be “all processors”.

Steve

I've just come across a utility from Intel which may help. WinTestCPUID.exe
allows you to select a processor and spawn an exe, and it comes with full
source code.
