Multithreaded Tools

[jpc82]

I finally upgraded my computer to a Core2 Duo e6750 dual core processor. Now I am looking into all the tools out there that support multiple CPU's to speed things up. I downloaded AutoGK which comes with Xvid 1.2 SMP and I went into the options and selected 2 threads. Also, I see Lame now has Lame MT which supports multiple threads. Should I download that and replace the one AutoGK uses with it?

Also, are there any other threaded programs I should be looking into?

Thanks,

MeGUI supports multithreading with x.264 - possibly others, but I don't encode in anything else anymore. There is also an AVISynth-MT that is in a kind of 'beta' state that can be used with different applications. It looked too complicated to me, so I didn't get much from it.

You can try replacing the one that AutoGK came with. At worst, it won't work with it properly and you can go back to the older one.

Just to clarify a common (and therefore confusing) misconception:

Multithreaded doesn't mean optimum use of multiple cores. Nearly every Windows application developed in the last 10 years or so has been inherently multithreaded - as has Windows (since the early 1990's).

Multithreading is merely the tool provided by the operating system to allow sections of code to run in parallel on separate processors. Unfortunately, some software vendors are touting how wonderful their software is because it is multithreaded. That's no different than saying my car's engine is better because it has more than one cylinder. Or having an HD television but only watching SD material on it.

The key to the performance boost is that the software developer identifies those areas of code than can be run in a parallel fashion. e.g., counting from 1 to 10 can be done in parallel by counting from 1 to 9 in steps of 2 and from 2 to 10 in steps of 2. The effect is the same but faster. Not all parts of the application can be performed in parallel.

Sometimes the parallel version of the application runs slower than the non-parallel version. Writing effective parallel code requires much more effort, skill and testing by the developer.
