Will an old application run on a dual-core PC?

[sansannah]

I use a software application which the manufacturer no longer supports. It was built six years ago and the manufacturer's literature said, at the time, that the application could "take advantage of multiple CPU machines running Windows NT/2000". I have been using the application very successfully for the past three years on a PC with one processor, running Windows XP Pro SP2 but, I want to purchase a new, dual-core PC shortly, on which I hope to install the application. My question is, will this application work successfully on a dual-core PC and, can I assume that this application is a multi-threaded one, since it was originally designed to take advantage of multiple CPU machines?

yes.

So which application is that? Who knows, someone might be still running that same software in his dualcore system. It's easier for us to answer if you write more specific. And yes, I'm very curious so as other people Welcome to the forums.

Welcome and yeah, even if for some reason it cant taake advantage of both cores (should be able to though). You can force it to run on one core via the task manager.

Thanks for the replies, everyone. I have just discovered today, Monday, from the software manufacturer's representative, whom I managed to locate in the UK, that the application is multi-threaded and is being used on both dual-core and multi-cpu machines successfully. However, it was interesting to learn that it is possible to force an application to work on one core using the Task Manager.

You set the CPU affinity to force it run on a single CPU.

Or a more comprehensive answer would be,

You can set the CPu affinity to force it to run on a single CPU...

...By pressing Ctrl-Alt-Del, going to the Processes tab, right clicking the process you want to set, selecting 'CPU affinity' and unticking one of the CPU's.

As a result of the replies that I received to this thread, my understanding of this subject has substantially improved. I've been to the Processes tab, as recommended by Richie P and I can now see how a single-threaded application could be forced to run, either on a single CPU or a single core. Brilliant and thanks to everyone!!!
