The obvious solution is to fix the application, or upgrade to a later
version that does synchronization and serialization properly.

Try starting CMD.EXE, setting it’s affinity, and then launching your app
from within that window.

Subject: [ntdev] How to disable dual cpu
automatically before launching an application

Hi,

I have an application that does not behave well when ran on
dual cpu
systems. I am looking for a simple workaround to disable one
cpu just prior
to lauching this application (ie: a batch file, or some
other trick).

I have considered other alternatives like:

  1. insert /onecpu in the boot.ini line => but this disables
    dual cpu for
    all app’s which is not desired.

  2. Start the app in question - do “ctrl-alt-del”, select the
    process, and
    right click to use the “set affinity” to disable one cpu =>
    does not work
    since the app is already started and damage is already done.

I would appreciate any suggestions.

Thanks!

Indeed, I don’t have the source code for this application, which was
released without knowing about this dual cpu issue. I am in contact with
the producer of this application to have them fix it - but, in the meantime
was looking for a workaround for the users who are already using it.

The “loader” program you recommend seems to be a good approach.

Thanks!
